Planning Issues for Self Contained Annexes

Originally written by Chris Hogan, updated by the editorial team on 16th August 2026

What counts as a self-contained annex?

A self-contained annex is an extension or outbuilding that includes its own living facilities. These are often built so that older relatives can stay close to family while keeping some independence. They also work well for grown-up children who want their own space, or for live-in carers and au pairs.

The appeal is obvious: everyone gets privacy, but help is nearby if needed. However, the planning and tax rules around annexes can be tricky. The main risk is that your annex gets classified as a separate dwelling rather than part of your existing home.

This distinction matters. A separate dwelling can mean a second council tax bill, different planning restrictions, and potential complications if you ever sell. Getting advice early, before you commit to building, will save time and money.

Planning permission considerations

Whether you need planning permission depends on several factors: the size of the annex, where it sits on your property, and how it relates to the main house.

Some annexes fall under permitted development rights, which allow certain building work without a full planning application. But permitted development has limits, and self-contained annexes often exceed them. If your annex has a separate entrance, its own kitchen and bathroom, and could function independently, you will almost certainly need to apply for planning permission.

When assessing your application, the local planning authority will consider how the annex will be used. They will want to know:

Who will live there and their relationship to the main household
Whether facilities like gardens and parking will be shared
How the annex connects to the main property

Planners tend to look more favourably on annexes that stay clearly linked to the main home. An internal connecting door, shared utility meters, or a condition tying occupancy to the main household can all help demonstrate that the annex is not a separate dwelling.

Some local authorities attach planning conditions preventing the annex from being sold or let separately. This protects against future subdivision of the property.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

Council tax and separate assessments

Here is where things get confusing. Planning and council tax are handled by different parts of the council, and they apply different tests.

The Valuation Office Agency assesses whether a property should be banded for council tax. Unlike planners, they do not consider who lives in the annex or their relationship to you. They look at the physical construction: does the annex have its own facilities? Could it be used independently?

If the answer is yes, the VOA may give the annex its own council tax band. This applies even if a planning condition says the annex cannot be occupied separately.

In some cases, annexes occupied by certain relatives may qualify for a council tax exemption or discount. The rules vary depending on circumstances, so check with your local council or visit GOV.UK for current guidance on council tax discounts and exemptions.

Getting the right advice

The rules in this area are not always consistent, and local authorities interpret them differently. What works in one borough may not apply in another.

Before you start, speak to your local planning department. Many councils offer a pre-application advice service where you can discuss your proposal informally and get a steer on likely issues. There is usually a fee, but it can prevent costly mistakes later.

You should also contact the council tax team separately to ask how they would likely view your proposed annex. They cannot give a definitive answer until the building exists, but they can explain how similar cases have been treated.

If your plans are complex, or if you are unsure how to present your application, consider getting help from a planning consultant or architect with experience in residential annexes. They can advise on design features that may help your case and handle the application process.

Taking time to understand these issues early will give you a clearer picture of what to expect and help avoid unwelcome surprises once building work is complete.

Why is there no follow up by local council as to possible mis use of letting out granny annexes.

The arrangement in my vicinity is to pretend there is a family member who will live in annex and then let out the annex and nothing is checked, unless a long suffering neighbour lets the council know

Annie 08/03/2021 at 5:31 pm

Hi we have a wide end of road plot (deadend), with a detached double garage to the left. We converted our detached double garage into an annexe in 2010 with change of use granted and building regs. no planning required as we did not increase the footprint. My son lives in it and I want to split the plot and give him title to secure his home for the future. Would that be possible?

Kitty 22/12/2020 at 8:57 am

There is NO mention of Building Control Requirements on this guidance - please do not assume if your annexe doesn’t need a planning app or it’s permitted development that you won’t need building control - you will, wherever new habitable accommodation or new bathrooms/kitchens etc are formed - regardless of the Annexe being integral to your house or self contained building in the garden, even if it’s a caravanesque shed arrangement on wheels - the drainage connection then requires notification

Welshman 22/11/2020 at 12:41 pm

Hi, we’ve knocked through a utility room into an office area to create a self contained annexe with its own entrance. While I’m aware we don’t need planning permission we’d like to create a small kitchen area with a sink. There seems to be some issues with this, it would be separated from the bathroom with a wall and door but not from the bedroom/lounge area. Any advice please???

Ang 18/11/2020 at 4:32 pm

We applied for a permitted development building to be erected in our garden at the side. I did seek advice from our ward councillor who told me that originally you would have to wait 3 years before you could separate the 2 buildings however she also informed that there was no timing to this regard and the NPPF has overuled it.
Does this mean that when the building work is complete we can move in and sell our original house. Many Thanks

GJ 09/11/2020 at 5:42 pm

I HAVE AN ANNEXE IN MY GARDEN THAT WAS BUILT BY THE PREVIOUS OWNERS WHICH HAS ANCILLARY USE WHEN THE PLANNING WAS APPROVED. THERE IS A KITCHEN AND SHOWER / WC ROOM IN THE ANNEXE.

I AM THINKING OF POSSIBLY AIRBNB NEXT SUMMER AND WANDERING IF I NEED ANY CONSENT FROM THE COUNCIL. PLEASE ADVISE AS WHEN LOOKING AT THE ONLINE ADVICE IT SEEMS THAT I DON'T NEED TO DO ANYTHING. (I THINK?)

LW101 23/10/2020 at 1:51 pm

Just wondering if anyone has converted their house into two living areas.
We have a disabled daughter at home with us and housing availability where we live is non existent for disabled.
I would like to convert the upstairs into a separate living area with kitchen minus a washing machine though.
Is this do-able and are their any restrictions ?

Jojo 20/08/2020 at 11:38 pm

I converted my stables and contacted them to my house in 2000. The property has been completely separate for 16 years and has all its own amenities except water which is shared.
I want to split them officially on the mortgage deeds and remortgage both sides.
Is this even doable? Do I need planning or is it to late now, 20years on from original build?
Many thanks.

Gringo 18/08/2020 at 7:10 pm

Hi, I’ve got a double garage on our property with a large garden adjacent. I’ve applied and successfully gained planning permission for an Annexe to be incorporated onto the end of the garage, we are going to have an elderly mother living in there, but may want to eventually turn this into an independent dwelling to rent out, I’m getting conflicting information about if this is at all possible? Is it correct that after 3years you can request the building to be deemed different to an annexe? Or can we apply for a change of use? Any views or ideas
Kind regards Gringo

Purno 16/08/2020 at 2:02 am

Hi,
I had an former double garage changed to an annexe in 2014 for my mother to move into but 6years on she now refuse to move into saying that she is happy where she is. Can I now let it out ?
It has it's own postal address and a lower band council.

Mig mog 06/07/2020 at 6:01 pm

My son has lost his job due to the ongoing corona virus and needs to raise some money for his mortgage Could I convert my garage for hi. To live in and he could then rent out his house to pay the mortgage ?

Tim 02/03/2020 at 7:33 pm

Hello,
I’ve rented out my summer house for 3 years to a family friend.
I want to declare it as a separate dwelling property because it has a small kitchen, en-suite & single bed.
My problem is, mostly the rent is paid in cash, so I don’t have any supporting evidence.
My house is a terraced house with side access to go the summer house.

I have two goals.
1) get permission from council to use it as a separate dwelling unit.
2) Extend the size of the summer house.
But first I need to get approval from council, that because I have rented out the summer house for 3 years now, it’s considered as a separate dwelling property.
It’s a London borough of Hounslow.
Please advise.

cam 27/11/2019 at 10:40 am

Hi there, I have an extension on my garage that was granted planning under permitted development as an " annexe ancillary to main house". I have since applied for business rates which I gat small business relief on to use on Airbnb which has been ongoing for the last 6 months or so. There has now been a letter for alleged breach of condition 4 in the granted planning, which includes letting out as a residential unit. Im not sure what the best way forward is, should I apply for a change of use to holiday let, or something else? I wish to continue with Airbnb for the foreseeable future. I have no issues with access or parking for guests and I live in a rural location with only one neighbour about 30 metres away, who has had no complaints with me. Also no parties are allowed by guests staying at the annexe. thanks I would appreciate any advice .

Al 03/11/2019 at 8:52 am

I want to move in with my sister and her family. To avoid over crowding we would like to build a selfcontained accommodation in the back garden we have been advised by a few log cabin companies that we can do this without planning permission if the building is classed as a mobile home but we would need to apply for a Certificate of Lawful Development as we are family members and will be using the main house utilities and occasionally spending time in the main house. Whilst researching this I have found conflicting information. What are you thoughts?

Mister H 07/10/2019 at 3:43 pm

Hi! Advice sought here.
I have a large detatched double garage which I would like to convert to an annex for my elderly mother-in-law. There would be no need to enlarge the building at all as it is perfectly big enough internally for the modifications I'd need to make. Would I (a) need local authority planning permission and, if so, (b) would I be likely to obtain such permission?
Thanks

Mister H 07/10/2019 at 3:38 pm

Hi!
Advice sought here please.
We have a large detached garage which I am considering whether to convert into an annex for my elderly mother-in-law. It already has a large rear window and side door together with both water and electricity supplies and is large enough to convert for a wet room, kitchenette, bedroom and living space. Would I need planning permission for this convertion (no need for any further exterior building work) and, if so, am I likely to be successful with such an application.

chipper123 16/08/2019 at 4:14 pm

Hi,

i have a detached annex on a large plot , the council the did a change of use with the planners they refused application as they wanted proof of seperate bills ansd own supply to the annexe i e own electric and water meter, as currently on sub meters, so 4 years have pass now so i decided can i build onto with no planning needed for new extension 8 metres Detached property? as its on a large plot

VJB 31/07/2019 at 12:17 pm

Hi, we currently live in my parents in law (large) garden; in a 3 bed one storey wooden annexe. It is fully functional with bedrooms, lounge, kitchen, bathroom etc and we pay our own council tax. As this is classed as it’s own property, would the likely hood of us being able to extend by going upstairs be greater? I know planning permission would still be required, but I just wondered whether paying council tax gives us a greater chance?

Cazza 03/07/2019 at 7:51 am

I bought a house with an annex, two separate addresses 3 and 3a my mother lives in 3a and it is a separate council tax. What I wanted to know is can I somehow change it back to one address meaning one council tax. At the moment we don’t pay because my mother is a dependent of me and over 65 but in the future I would like it to be one address. What can I do please ???

Pinkie 11/04/2019 at 6:39 pm

We had a large stable block which was given permission to convert to large 5 bedroom dwelling. We did this and then blocked couple of the doorways off so our son, daughter in law and 3 grand children could live there. The council came and checked it and said that as my son had got his own kitchen, they would be charging him his own full council tax, as well as our full council tax. We have both been paying this since we moved in 2006. I have now read that since 2014, a discount of 50% can be claimed for an annexe, provided that it is used by a relative of the person living in the main home, which it is. My only query I have is that is their part of the house classed as an annexe?

BDeyes 10/04/2019 at 6:57 pm

Can I build annexe to live in then sell main house in uk

BDeyes 10/04/2019 at 6:53 pm

I cannot afford to live in my 3bedroom bungalow,can I build granny annexe in large garden, move in then sell bungalow

EMG 04/04/2019 at 2:41 pm

We have a derelict former servants' quarters in our back yard. Our house was built in the 1750s and the derelict servants' house was accommodation for the servants of the main house (ie our house). The derelict house was lived in until the 1980s when it was closed as unfit.

We are restoring the derelict house and have built a small extension off it. We did not apply for planning as the extension is smaller than the permitted development limit.

The restored house is intended for elderly parent in the next few years but in the meantime, we would use it for visitors and for self-catering holiday lets in the summer.

The only access to the restored house from the road is through the grounds of the main house. There is no separate access to it from the road.

Would the restored house be considered a totally separate dwelling (with its own postal number) or would it be considered ancillary to the main house?

If considered ancillary, would the small extension require planning permission?

This last question seems to find no answers on the web.

Kim 27/03/2019 at 1:59 pm

Hi there,
We have a 3 bed property with a big garden we would like to build a type of one story building sort of a annex but only with sleeping and bathroom facilities.
The reason for this as we would like to extend our family and our teenagers would like their own space. Would we need planning for a single story either log/brick building with just a bedroom and bathroom at the bottom of our garden?
Thank you

Mermanda 31/08/2018 at 8:29 am

Hi,

My partner's mother has agreed that we can build a 2 bed wooden cabin in her garden. It will be a single storey unit but will be used as permanent accommodation for 2 adults and a child. The plan is to be around as carers for her as and when she requires.

Would this need planning permission?

Thanks

AJ120 18/08/2018 at 9:41 am

Hi, I have been reading through all the questions and answers which is very interesting and useful. We are in the process of buying a house which has an integral double garage with bedrooms above it which was all part of the original build of the property. We want to convert the garage into an on suite bedroom and kitchen diner for my mother who is recently widowed. She would like her own front door separate from the main front door and she will also have a lounge area which is part of the existing living area of the house. As far as I can tell we do not need planning permission, but do need change of usage and building regs for the work. Would this fall into the category for separate council as do you think? ( my mum is aged over 65 so as far as I can tell even if it does it would be exempt for her).? Thank you in advance.

Lizzy 23/05/2018 at 4:21 pm

We’ve found a property which has Planning conditions attached to it. The planning conditions state that “The dwelling shall be used for single family occupancy Qaeda not split for use as two or more separate dwelling units”. We understand that the main property and the annexe both have separate postal addresses and utilities at this time. Does this constitute a breech of planning permissions. If so what would need to be done to rectify the situation? Thanks

ExtensionBuild Editor 23/05/2018 at 3:49 pm

This would probably be considered a self contained annexe and you will be required to pay separate/additional council tax. Talk to your planning officer about what planning permission might be required in your area (they will give you advice for free, but obviously if you do need permission you will have to pay the application fees).

Blink 23/05/2018 at 7:39 am

Hi, I have a 3 bed bungalow which I am planning to extend into loft and rear to rent out with a separate entrance into converted loft (via stairs) with 3 beds/baths , an open kitchen with a lounge. Reading upon your other blogs, it is understood there might be 2 council taxes to pay as a 2nd kitchen installing upstairs. I want to keep one single main entrance to the property with 2 separate doors from the porch accessing the ground and top portions.

Can you please advice what type of planning permission is required to make this build and rent the upstairs as a single unit or independent rooms while landlords living in the ground portion?

And what other mandatory things that are to be considered in this scenario?

What are these type of extensions called - a separate dwelling or a self contained annexe or separate flat?

Appreciate your genuine and swift response as it is very important to know before time runs out.

ExtensionBuild Editor 22/05/2018 at 3:49 pm

He may need planning permission for this as it's going to slept in/used individually rather than used as a an additional family room. Check with the council tax as each area seeems to vary the rules slightly.

soph 16/05/2018 at 8:03 pm

Hi there, my brother owns his own home and already has planning permission to extend the living space and kitchen, he also has a garage at the bottom of the garden that he either wants to convert into a self contained living space for me and my son or knock it down and build a "granny annexe" for us, we would only have space for bedrooms, small living space and a toilet/sink and will be using the main house kitchen to cook, bathroom to shower and main living space during the day. Would getting planning permission for this affect the planning permission already in place for the extension? And would I have to pay council tax even though he wouldn't be able to rent it out on its own as it won't technically have a bathroom and won't have a kitchen?

ExtensionBuild Editor 04/04/2018 at 11:30 am

If you are going to be adding facilities like a bathroom or kitchen, you may need planning for change of use. The easiest thing to do is ask your planning officer, they will give you advice on this free of charge.

Linda 01/04/2018 at 2:45 pm

Hi we have recently built a double garage with home office over and obtained the relevant planning permission. I am now thinking it won’t be used much and is so big we could convert to living accommodation for my daughter on her return from uni. Do I need to get planning permission again for change of use from home office to living quarters ? I am also thinking I might be able to rent it out with air b n b. Would this also be an issue ?

Anna 07/03/2018 at 8:22 pm

Hi. I would like to get some advise on the following. I have a basement thst is converted into an annex with kitchen, bathroom, living area with a shared door to the utility room with the house and it also has its entrance. The sbared door also leads to the kitchen via staircase. I have planning permission but the council has just send me a letter that they want a site visit to see that the annex is used ancillary to the main dwelling and not independently. What does this mean? Does it matter who lives there? Thanks.

ExtensionBuild Editor 05/03/2018 at 12:51 pm

Usually if it can't be "let" separately (i.e no kitchen) then you wouldn't have to pay Council tax. Building control permission is usually only needed for structural changes etc. Bricking up your external door might not be an option because of building control, but if there's an open arch way/ or double french doors etc into the bit they are classing as an annex. Then no kitchen or bedroom, it's quite clear that you aren't using it as such. It might be worth asking a valuation or planning consultant for specific help.

Overtaxed? 02/03/2018 at 11:27 am

Hi, To clarify we are trying to find out what modifications we can make (if any) so that VOA don't think we have an annexe. Hopefully we can make these without planning but not sure if we need building control.
Thanks

ExtensionBuild Editor 28/02/2018 at 1:58 pm

Is this a question for council tax purposes? Planning? Building Control? Sorry it's a bit unclear.

Overtaxed? 27/02/2018 at 11:11 am

Hi,
We have an area of our house that has an external door and a doorway from the kitchen. Upon purchasing the kitchen doorway was locked and bricked up, both door and bricks have been removed. The area was a kitchen/bathroom/bedroom & lounge. We thought we could convert to Utility/Cloakroom/Study/Snug but council think otherwise. What do we need to do to make the conversion in the eyes of the council. They will not tell us and will not even answer questions such as "what if I brick up the back door?" Any advice would be appreciated thanks.

Marian 04/01/2018 at 5:47 pm

Hi ive just bought a house and want to build an annex in the garden but have no idea where to start. Can you please help and advise me. Thank you

Kim 22/12/2017 at 10:53 pm

Hi there ive recently bought a house that the previous owner said that one part of her barn had planning on it for a annex im wanting to turn it into a annex but dont no where to start could you help me with this.

Kez 19/12/2017 at 11:30 pm

We are thinking of converting a part of our house into a self contained studio flat to rent out but we have no idea where to start?

woodlandwonderer 22/11/2017 at 9:52 am

Hi there, just looking for some advice please...
My family and I have been living in a self contained annex on my in-law's land for over a year now and we're thinking we would quite like to extend the annex in the next year or so. One of the issues is that technically my in-laws live i a flat, it's a large house split into two. My question is, would we need to get planning permission to extend?
Thanks in advance!

Hopeful 20/10/2017 at 4:34 pm

Does anyone know if councils allow the build of a granny annex in the garden of a council property? It is a very large garden and would not infringe on anyone's privacy.

ExtensionBuild Editor 17/10/2017 at 11:39 am

You will need to check with your planning department if it's now used for residential purposes as that constitutes a change of use. If an annex or outbuilding is self-contained with its own living area as
well as cooking and washing facilities/toilet even if it shares common services with a main building, is still liable for council tax. So you will need to pay separate council tax on the coverted barn. Discounts may be applicable if your father is a pensioner etc

ExtensionBuild Editor 17/10/2017 at 11:15 am

You should contact your local plannign authority about this. In general, no more than 50% of the area of land around the original house should be taken up by other buildings. You will need planning permission for any change of use (eg if these buildings were for residential use rather an simple a garden office etc).

Reb 16/10/2017 at 12:13 pm

Hi,

I wonder if you could advise me, we recently moved into my father's house and converted his garage/barn into a place for him (kitchen/bath/bed) it is separate to the house but runs off all our supplies so we pay the bills.

He built it over 20 years ago and I'm pretty sure never got any planning. What should we do? and is he aloud to live there? Also we are obviously paying council tax for the house, but do we need to do anything more Council Tax?

Very much appreciate your feedback and thoughts

Thanks

tonyuk 16/10/2017 at 11:44 am

Hi

I am planning to buy a property for buy to let, it has good size garden where you can build 2 annex 20 x14ft size, but then there will be very small part of garden left.

Can you please let me know how much garden you have to leave for house if you build annex?

Thanks

Sid 15/10/2017 at 9:08 am

Hi, my wife and I are considering building a annex/bungalow/what ever other name you can think of, for her disabled mum. It would just be bedroom, shower room, and lounge kitchen. My garden is a good 30m long so I have the room. What do you think is best? Because we would be caring for her also.
Thank you

Giggsy 13/10/2017 at 6:15 pm

If I build a self-contained annexe for rental. What is the minimum area, and does it have to have a garden ?
Thanks for any help

ExtensionBuild Editor 13/10/2017 at 11:38 am

Yes this would need permission if you plan on living in it. If you contact the planning department of your local council, they will be able to tell you how to apply.

Gabyfallonos 12/10/2017 at 2:19 am

Me and my partner are interested in building a ‘log cabin’ in his childhood home garden, which is quite long and fitting for it. The whole do you need/don’t you need planning permission is really confusing! It’s purpose is to allow us to live together and save for a family home so I’m guessing it would require some type of permission how would I go about this?

ExtensionBuild Editor 06/10/2017 at 2:29 pm

It's likely that this would be considered change of use and are creating a direct access that we assume wasn't there previously. Your planning officer will be able to tell you (free of charge) whether or not you need to apply for planning permission.

Simes 04/10/2017 at 4:12 pm

We have horse stabling at the bottom of our garden and use the fields behind to graze horses.

Our existing drive way from the front of the house terminates at an old prefab garage (at one side of the house)

Would we need Planning to remove this garage (it is not original to house) and extend our drive to the stables (about 100 metres down the bottom of garden)

We live in a semi rural/urban area in Maidstone

Cannot find any information about this on the web.

Andrew 25/08/2017 at 10:59 am

Hi, I am in the process of buying a property which has a detached annex. It's previously been described as an annex in 2014 when it was sold to the current vendors but on the current description it's a garden studio! My question is do I need planning permission to knock the "studio" down and build a new annex (for my parents to live) or should I add to the existing building? Thanks

ExtensionBuild Editor 08/08/2017 at 12:55 pm

Contact your planning department and find out whether you need to apply for "change of use" permission.

JAY 06/08/2017 at 12:05 pm

Hi, i bought a property in 1998 with a seperate detached brick built bungalow, seperate kitchen and bathroom that was previously converted in 1986 to a "granny annexe" . We have always had to pay seperate council tax on it, although weve mainly used it only for the kids. I wished to rent it out to my oldest son, or sell it to him as he has just been made homeless from a long term let in Brighton, yet Ive been informed by the council I cannot charge rent on it, due to the fact its use is ancillary to the home, and its a granny annexe, regardless of the fact we pay rent on it. We are looking at selling it as a seperate dwelling to him now but how easy is it to split it from the deeds and what type of change of use do i need to obtain?

ExtensionBuild Editor 04/08/2017 at 2:53 pm

The Council tax rule can refer to properties that can be "let" as a separated entity not just "sold" separately. The fact that the annexe shares common services, or cannot be sold on its own does not prevent it being self-contained. Council tax is most likely payable. The occupier of the annexe is usually responsible for payment, but if the annexe is unoccupied, the owner of the main house is repsonsible. There are certain exemptions and you should contact your council to find out more about these, but sometimes they can include an exemption if the annexe is unoccupied there is an exemption (Class T) available if it cannot be let separately from the main dwelling without breaching planning conditions. (An exemption also applied if a dependent person aged 65 or more is living there).

Lynda 02/08/2017 at 10:20 pm

Hi my mother passed 4 weeks ago she lived in an extension that we had built on the side of the house we also had a bedroom built with en suite above the extension me my husband and 3 children live in the main house my daughter will eventually be moving into the extension which is not detached and has a connecting door the ext has a bathroom bedroom kitchen and living area. We have received a council tax bill demanding a payment which is dated from the date mum died. We could never sell it as a separate building as it is an extension which is written all over the plans which were approved in 2004 will we need to rip all the rooms out? I am so disgusted as a care home would have cost the council thousands please advise

Elle 09/07/2017 at 3:10 pm

We have bought a property with our son, every thing done correctly with deed of trust in place. Included in the property is a detached coach house with planning permission already in place to demolish and build a three bedroom town house. How do we proceed with removing it from the title deeds of the main property , will the mortgage company object and will it affect the value when and if separated . Sorry confused?

Aaaa 22/03/2017 at 6:01 pm

So... this is a minefield isn't it? Anyway you do this the council will just want to find money. Our story is a little different, we built a small two bed cottage 15 years ago, because we worked away and to ensure my parents lived in a reasonably comfortable home we asked them to live there (at no cost) when we finally decided to settle down we went to our council to ask to build an extension which would allow us to live next door to my parents and not ask them to go into care, effectively we would end up being their carers - doing what you do to look after your parents (isn't this what the government wants? taking the burden away from social care????). Anyway the extension would mean the second bedroom would be a bedroom for our son (or possibly ours). We were told by the council that it can not be classed as two dwellings, we had to knock a door through the building so we all lived together..... ok.
Revenues man came hounding, intimidating, did not say who he was and what he wanted whilst building works was still under way,
We share the same oil, same electric, same water, we did leave their kitchen in to give them some bit of independence, however whether the kitchen was there or not they would class it as two separate dwellings (revenues office) aaaaaaa.
I was then told to write a letter to say that the new extension was an annex as we would get a discount - now they say there will be no discount as my parents will continue to live in the original building whilst we live in the extension (same size but more modern which suits our taste) oh my gosh...... I'm sorry, but what do we do, I feel aggrieved to think we have to pay two council tax bands when they specifically told us we could not class it as two dwellings, we have no rent from my parents even though they live in our house which we built rent free and we are looking after them so they do not go into social housing - is this fair?? I feel sick, working hard to save all of our life, living somewhere to care for my parents but having to pay another set of rates - we live in the country so have no services such as bus or street lights etc.
Why can't the orgiginal house be classed as the annex as it's now a one bedroom home to house two 84 year olds???? Even a 50% reduction would make a little difference - unbelievable.

It is not clear at all! It's pretty disgusting.

Hi there,

I am planning to do side extension i.e., already a living room exists and want to extend at the rear of the living room by 3m(with a separate bathroom and kitchen). I know that a planning permission and building reqs are required for the side extensions. But can you please advise me with this plan how can I make this bit as legal thing and don't want to get into trouble with the council guys?

Thanks,
Sid

We are making plans to extend our house by one room off the kitchen which would be used as an extra living room/ snug as our main living room is on the middle floor, but if my 90 year old Grandad needed extra help then this would quickly be converted to his living area with a wet room added on into the garage. Would we need planning permission and would this effect our council tax?? he would have direct access to our kitchen but we would fit a kitchen sink/ kettle/ microwave. Any advice would be greatly appreciated

Sophie 09/01/2017 at 8:20 pm

Thanks. Yes council tax was charged 6 months so we are paying 2 council taxes. Nothing was said about did you get planning but obviously that was the next step to find out. My husband friend is saying if we take the kitchen out I.e the cooker and extractor it should be ok. But it still has separate entrance and kitchen units etc.... don't know what we should do I think best thing is to.leave and see what they say they are coming tomorrow.

ExtensionBuild Editor 09/01/2017 at 2:35 pm

The council's planning department will be able to tell you what the options are. You may have to apply retrospectively for planning permission and await the decision before either carrying on as before or reinstating the building to its previous state. Your council tax will also be affected by this.

Sophie 07/01/2017 at 9:18 pm

We bought a house with an extention in place. We blocked off the walls and turned it into a self contained unit to rent out with separate kitchen, bathroom and entrance from the back. We did not apply for planning permission as we really didn't know but now someone from council coming to inspect. What will happen from this could we now be able to apply for planning permission without taking it out? Any advice or guidance will help.

sue 29/12/2016 at 11:07 pm

i am thinking of buying a house with an attached garage and a door into a 20foot by 8foot extension which at present is used as an office. it could be made into a mini flat with shower room and bed in garage area and small kitchen and living space in the extension area. what are planning implications and would it be liable for a separate council ta. thanks. sue

ExtensionBuild Editor 20/09/2016 at 2:13 pm

We can't advise on specific individual planning case where we don't have the full details. You may be better seeking the advice of a planning consultant.

Rosh 18/09/2016 at 11:23 pm

I have recently applied planning permission to use my outbuilding as a annex but council refused the planning permission. They were saying it is separate unit not a annex as I had a electric hub installed before. It was already removed and reapplied for planning. The council again change my planning heading from Habitable Use to self contained unit. Can you please advise me how do I approach. I am truly stressed.

ExtensionBuild Editor 15/09/2016 at 12:47 pm

Clearly the council is reluctant to provide planning permission for this. You should contact social services and ask them what the alternatives are to keep your mother safe and cared for. They may be able to support your case or offer some alternative suggsetions.

I'm at my wits end in N Ireland I have a stand alone double garage My mum and dad are elderly mum has went into a wheelchair full time and there house isn't suitable They would need to start knocking lots of walls down as corridors to every room are not wide enough for wheelchair and in most rooms the wheelchair could not be turned
Hence we thought if we made the garage into a bedroom lounge shower room and small kitchen mum could use her wheelchair plus we would be at hand to help as both parents are not to well
The architect put in a change of use and small extension but have not joined it to the house as no 1 it would take up a lot of space trying to join it as it couldn't be squared off plus if it was joined it would mean half the house mum could use and the other half wouldn't be wheel chair friendly plus it's nice to have your own space
The planning asked for medical reasons and why we couldn't build up so I got them letters from doctors ministers etc who said it was getting dangerous for mum as she was falling without her chair and reason why we can't build up is because there is no where in the hall we could put stirs never mind a wheel chair lift and now they have come back saying why does it have to be in your house that care is given and can you prove it a hardship if we were turned down
I don't know where to turn to and in fact what more I can do. We are not asking the government for any money they are willing to use the sale of the house the extension is looking into our own property at the back garden
Can anyone tell me where I can turn to or what else I can do. I'm totally gutted it has been going on a year and I think plans keep moving the goal posts I haven't told mum and dad yet as I know they are depressed waiting for the planning to come through myself and my husband are having to travel 10mile round trip daily to do things for them

ExtensionBuild Editor 16/06/2016 at 12:57 pm

It might be expensive, but a planning consultant can often help in situations like this. They no how to handle planning committees, often know the rules inside and out, they'll probably be acquainted with the planning officers and can negotiate acceptable amendments etc for you. It seems strange that in general, rules on extensions have been relaxed to enable more people to stay where they are (less demand on the housing stock), yet your council is clamping down.

Dan 15/06/2016 at 10:48 am

We've applied for an L shaped extension to the side/rear of our semi detached house (with shared drive way) to accommodate a disabled bedroom and bathroom for my elderly father. We have been told by Harrow council that this will be declined as they want to stop developments like this, even though one immediate neighbour has one and another two doors away.

We have proposed a larger door to the front of the extension (bottom of the shared drive way that will face that the street) to accommodate wheel chair access, but we have been told that there are multiple issues relating to the size, the door and other stuff which they have not yet told us until the determination is made in mid July. How best can we handle this? I know medical grounds do not impact planning decisions, but it seems unfair that the neighbour did theirs in 2002 and 2007 respectively.

I am in the process of trying to obtain the annexe from my family. It is a wing of a grade 2+ building, and is currently rented out. Council tax has been paid stove the conversion 8 years ago. Is a change is use likely to go ahead, or will asking draw unnecessary attention to the fact that it is being rented out. I want it to be classed as a separate dwelling

Roxie 17/09/2015 at 4:13 pm

We viewed a perfect bungalow that is for up for sale and put an offer in for the asking price but was then told that the loft area that is split into a master bedroom and bathroom did not have planning permission. We withdrew the offer and now wonder what are the implications if we did try to buy this property? Could we get permission or building control sign off in retrospect?

ExtensionBuild Editor 08/09/2015 at 12:22 pm

Apply to your planning office for a "change of use" permission.

Sam 07/09/2015 at 4:26 pm

I have an outbuilding that has a Planning consent (issued in March 12) to be used as home office Gym. It has a kitchen (with gas cooker etc) and shower facilities. a Building control Certificate has been obtained for this development. I pay council tax and also have annual gas safety / Electric certificates.
I also have a letter from the neighbourhood services stating the property could be let out.

I would now like use it as a separate unit and (officially) rent it out.
Could you please advice what Planning permissions should I seek ?

katy 23/01/2013 at 9:41 am

We have two annexes built about 9 years ago and have rented them out for the last 9 years. council tax has been paid on them for the last 5/6 years. now my neighbour has complained to the council & we are waiting for the enforcement officer to inspect.The official wording in our permission to convert to residential is that they have to be used as ancilliary to the main house and for the owners/occupants therein & for a permantly employed groom. We are an equestrian yard and both the tenants keep their horses here, share the driveway and all the facilities.Do you think we are in breach and what do you think the chances are to change the wording on the permission so that we can continue to rent them out?

jules 15/08/2012 at 10:50 am

I too am in the same position as the two comments above but as yet have never paid council tax for the annex. Ours is a complete seperate entity, not joined on, it is a two bedroomed bungelow with bathroom, kitchen and lounge/diner.

We woud like to get permission to seperate the two and sell it as a standalone property. Originally the council said they would never let us? but they also said they would never let us convert it but we too it to appeal and won! what would be the chance of getting permission and how would we go about it?

rosh 07/08/2012 at 5:53 pm
