Building an extension to rear of house

canhefixit

I just want to see if what I have read I have understood correctly, can I build a rear extension without needing planning permission as long as the whole extension is less than 40sq meters altogether? I would have to have 20sq meters on ground floor and the same on first floor?

So if I was planning on extending do I even have to notify the planning office at all or if its under the 40sq meters can I work away? also do I have to get the final works checked by building control or someone from planning?

Cheers

Not just as simple as that as there are conditions that need to be adhered to - see here

Just to add that IF your proposed extension is classed as exempted development then you do not have to submit a commencement notice but the works will have to carried out in accordance with Building Regulations and to this end you should engage a professional to both design, inspect and certify the works upon completion.

From your response "IF your proposed extension is classed as exempted development", how dp you mean if? do I have to seek permisson or put forward plans with specs etc and then will be given the go ahead or not?

What im thinking is using an architect or a builer to design the extension to how we want and to spec and to meet the regs, after that I thought I could then build away is that not the case?

Thanks

Your proposed extension will only be exempt if it meets the conditions I linked to. As an example you havent said in your post if your house is detached or semi-d or terraced nor have you indicated the area of open space remaining. Those have a big bearing on your proposal so that is why the word IF was used.

The house is a detached 2 storey property on a 1 acre site, there is a drive around the whole house about 2.5 meters wide of tarmac, past that is just garden all around, loosing the drive all around the house is not a problem as there is a separate garage anyhow, I can go as far as I need into the garden as the house is almost centred within the site so plenty of ground to play with, there are no roads or lanes behind the house just fields.

This is where confusion can arise at times as there is no "one size fits all" and I even recall cases where planning staff give out the wrong information. As an example if your house had been a semi-D or terraced then 12 sq. metres is the max you can build at first floor level under the exemptions.

Anyhow if you stick to the conditions then your extension will be exempt from planning. But just to repeat that it will not be exempt from the building regs though and this is why I said you should get a professional, arch/arch tech/engineer, involved to make sure that the works when completed will comply with all statutory regs.

Further down the road you may be glad to have availed of this advice.
