Shed Conversion

[smallzz]

Hey all,

Has anyone here attempted a shed conversion to be an extension to the house? We have 3 (all joined) brick sheds and a coal shed in our 50's Semi, The sheds run alongside but extend out into the back garden. They've got a concrete flat roof which is waterproof and the buildings are damp free and structurally sound. Ideally we want to extend it to past the side door of our house and use a current area which has a semi built wall up on it.

I know a bit about DIY so some of it should be quite easy and the electrical stuff I'd rather pay to get done than do myself. I do have a few questions though which I'm hoping some people could help with.

Do you need planning permission to repurpose an already standing building (attached to the house) that wont affect the neighbours as its below the height of their house?

Would it be easy to extend the concrete roof with other materials or would it be best to have the whole roof replaced?

Check with your local planning office first - that's where I would start - no point in messing around with stuff till you know whether you need planning permission/building warrant etc.

Also if your going to use it as an actual room/extension - I would seriously consider a builder/firm of some kind. Walls/roof may look fine to you or I, but whether they could support additional weight/walls etc is another story.

Assume it’s ex council?

Assume it’s ex council?

I'm guessing so. It's been privately owned for about 20 years I believe.

Will. Check with the council then.

Yeah might get a professional in for advice.

This would fall under permitted development i.e. you don't need planning for it, just BC sign off.

I think they've just relaxed rules further as well...

This is a very simple response to a complicated quesion. Whilst extensions to dwellings can be "permitted development" there is no where near enough information provided by the OP to know whether what he wants to do would or would not be lawful.

Class A, Part 1, Schedule 2 of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) grants permisison to alter a dwelling and includes an extension that would "consume" your existing outbuildings. The development would need to comply with the condiitons and limitations of Class A to ensure that the development did not require express planning permission from your Local Planning Authority (LPA). You also need to ensure that Class A has not been removed from the land by your LPA.

Only last week I visited a woman (I am a LPA Planning Enforcement Officer) who had wrongly carried out work to her property that required permission. When I asked her, "did you seek any professional advice?" her response was, "I read on a internet forum that I didn't need planning permisison".

Many Council's offer different levels of advice and if not there are plenty of independent planning advisors who will help you for a fee.

And then people wonder why they are having to fork out a few hundred quid for indemnity insurance when they sell good post

Granted, but it still would likely fall under permitted development rules.

The referred temporary legislation referred to has been made permanent: http://www.legislation.gov.uk/uksi/2019/907/note/made :

Regulation 4 makes permanent the existing temporary right to enlarge a dwellinghouse by up to 8 metres in the case of a detached dwellinghouse or by 6 metres in the case of any other dwellinghouse, as permitted by Class A of Part 1 of Schedule 2 to the Order. It removes the time limiting date of 30th May 2019, as well as conditions which required development to be completed by that date.

And, to be quite frank, it's already built, so it's not an extension is it? OP has used the word extension, but actually, it's already as existing and all it sounds like he wants to do is convert into more useable space. I doubt that realistically needs anything beyond BC.

Probs best not to argue with a planning officer - you are still making assumptions and whilst you have likelihood on your side, assumptions none the less. There are a great number of further things that will be considered before permitted development rights are granted. I guess that based on the info provided, it is unwise to make assertions one way or the other regardless of the likelihood as mentioned.

It's impossible to be certain what the OP is intending to do without the benefit of viewing plans. To suggest or advise that the work benefits from permission without knowing the full details is, frankly irresponsible. Twice it's been mentioned that the legislation has recently been changed however frankly that's a relatively small (all be it helpful to home owners) amendment to legislation that has been amended several times since it came into force in 2015.

Class A, Part 1, Schedule 2 only covers extensions, alterations and other improvements to the dwelling house. It's not clear whether the changes the OP wants to make are solely to the dwelling, outbuildings or whether there is an alteration to the roof of the dwelling.

The legislation is both a blessing and a curse. On one hand it provides land owners with a variety of permission that is "deemed" to be approved without going to their LPA. The downside is that you need to be sure that you understand the legislation. If you are concerned then you can go to your council and have them, through the process of applying for a lawful develpoment certificate, to confirm that what you want to do is lawful which to some extent makes the "deemed" approval somewhat pointless.

If anyone is thinking about selling their house and is worried that a potential purchasers will question the lawfulness of development on their land I would always recommend that they consider this long before selling. It is incredibly frustrating when we as an LPA receive correspondence from sellers solictors asking for lawful devlelopment certificates at the last minute of sales and then disapointing them when they find out the application process is 8 weeks.

Below, contained within a "spoiler" so not to clog up the thread is the precise legisaltion (original, you have to read it conjunction with the numerous amendments) that grants various permissions to home owners (the wider legislation covers a variety of land and property but for the purpose of this thread we are talking only about Part 1, dwellings)

As I said before I don't doubt your intentions to be helpful but it is misleading to suggest that something id lawful based on such limited information. I cannot count the number of times that I have been out on site and owners/developers have quoted part of the legislation confident that the development is lawful only to assess the developmetn point out to them that they have either missed something or misunderstood the legislation.

Yes, but from the information he has given (admittedly limited) he hasn't once said he'll be extending what exists and simply bringing what are attached "out buildings" into a more usable space i.e. they already are in use as stores or whatever and have extant permission to be there having been built with the original property.

In my eyes, it's no different that refurbing an existing premises...

The OP said:

"Has anyone here attempted a shed conversion to be an extension to the house?"

Now I read that in conjunction with the rest of the post to mean that he has several outbuilding in close proximity to the dwelling and wishes to attach them to the dwelling. If I am mistaken I am sure the OP will clarify this.

If I am correct in my assumption then Class A, Part 1, Schedule 2 of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended) [henceforth simply the GPDO] and its conditions and limitations will apply. If not and the intention is to not "attach" them to the dwelling then Class E, Part 1, Schedule 2 of the GPDO applies.

Regarding your second paragraph be very careful in assuming that "refurbing" does not require planning permission.

Briefly:

Planning 101

The very first question in any planning question should be "has development, as defined by Section 55 of the Town and Country Planning Act 1990 (as amended), occured".

Section 55 2, (a):

(2)The following operations or uses of land shall not be taken for the purposes of this Act to involve development of the land—

(a)the carrying out for the maintenance, improvement or other alteration of any building of works which—

(i)affect only the interior of the building, or

(ii)do not materially affect the external appearance of the building,

and are not works for making good war damage or works begun after 5th December 1968 for the alteration of a building by providing additional space in it underground;​

What this means is that if you are internally "refurbishing" a building there is no devleopment and therefore no permisison required.

If however you are making changes to the external appearance of the building the Section 55 1 applies.

Section 55 1

(1)Subject to the following provisions of this section, in this Act, except where the context otherwise requires, “development,” means the carrying out of building, engineering, mining or other operations in, on, over or under land, or the making of any material change in the use of any buildings or other land.

(1A) For the purposes of this Act “ building operations ” includes—

(a)demolition of buildings;

(b)rebuilding;

(c)structural alterations of or additions to buildings; and

(d)other operations normally undertaken by a person carrying on business as a builder​

Therefore external "refurbishment" is almost certainly development and will need permission. Depending on the specifics of the development, it might benefit from permission by virtue of the The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). If the development does not comply with the Order then express planning permission is required from the LPA.

Thank you for all of the help.

To clarify the outhouses are attached by only the roof to the house currently. The outhouse walls form an L shape with a walk way between the house and the sheds to the back garden which is covered by the concrete roof. There is also a little alcove with a wall half the height of the shed walls which would be the furthest point out of the extension which would need the roof extended by 4 foot. The rest of the sheds would be simply knocking down internal walls and putting walls where the current "doorway" minus the door exists. All 3 outbuildings are all joined currently.

We're the only ones in the street that haven't converted it so it seems like a was of needed space.

Any questions feel free to ask and I really appreciate all of the help.

This is one of those instances where a diagram is worth 1000 words.

In all seriousness go and ask your local planning authority for advice, they well be able to resolve this relatively quickly and unambiguously.

Getting planning permission isn't expensive, trying to sort it out in retrospect is. Given every other house on the street has been done its unlikely a similar project would be refused if its required.

You then have to deal with all the regs if you want to make it a habitable space. All the electrics etc. will also need to be certificated.

You'll need to ensure the internal walls are not supporting the roof, they may well be.

Unless you know 100% what your doing you really should be getting a pro in for this.

Yeah I'm going to get a contractor in to take a look and give me a quote and go from there.

To make them legal living space may well prove challenging as you will have to comply with building regulations for insulation and the like as they are not currently part of the house. It could prove cheaper to knock them down and start over.

First step for me would be to sort planning even if you are convinced it’s permitted development draw it up and submit it to be sure. You can do the drawings yourself they don’t need to be amazing do all it will cost is the submission.

Then get some builders round to quote and be ready for it to cost significantly more than you think in your head it invariably will.

Hello

"To clarify the outhouses are attached by only the roof to the house currently."​

Okay, the above statment clarifies that the buildings are attached to the dwelling.

"which would need the roof extended by 4 foot."

&

"putting walls where the current "doorway" minus the door exists."​

these statments suggest a material change to the external appearance to the building and therefore the work you intend to do will be development. If you want to do the work and not require express planning permission from your LPA you will need to ensure that the work complies with Class A, Part 1, Schedule 2 of The Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). You will also need to ensure that no previous planning permission granted and implemented removed by way of an imposed condition Class A.

Good advice here, working from plans (or in my case often literally on site with an extension or building) is much easier than a description.

Many LPAs will be helpful but you may need to pay for some of their services or seek independent (and paid for) advice.

And as suggested above it's not just planning you will probably need Buildign Regulations approval but can't help you there as that is seperate legislation from planning and I know next to nothign about Building Regs.
