Building Regs for a Garden Shed?

psarinuk

Hi,

I've a 3 bed mid trerrace house that has recently had a single storey rear extension.

I am now planning to put a 7m by 3m CONCRETE SHED at the bottom of my garden (across the whole 7 metre width).

I think I don't need planning permission based on the following:
1. The size of shed plus house (with extension) is no more than 50% of size of land.
2. Since I am building on the rear garden boundary, the max height is 2.5 meters (the top of mono pitch roof).

Regarding, building regulations, I am a bit confused:
Building Regulations
If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed of substantially non-combustible materials.

The shed is 7m by 3m = 21 sq meters, however, it would have no sleeping accomodation and would be built from 100mm 7N/ 7.3N concrete blocks, along with a UPVC door and 2 UPVC windows.
Do I conform to substantially non-combustible materials? Is there any way I can improve on this front?

Thanks in advance..

I've often found the Planning Portal (Govt guide to PP issues) useful. If I recall rightly, they have an interactive slideshow which takes you through the various rules.

Might be worth having a look to see whether it answers your questions.

What is the proposed roof construction? Timber by any chance?

111KAB,
It would be a mono pitch tiled roof, same as my recent single storey rear extension. The tiles would be matching to the rest of house.
Thanks.

The point I was making is that the tiles are most likely laid on timber mono trusses/rafters and the timber is combustible. Whilst the wall construction may protect your neighbours from a possible internal fire the roof construction may not hence one of the reasons for the 1.0m gap to the boundary.

I take your point but some timber has to be used even in a flat roof. Compare this to total timber sheds which my neighbours have and I think the materials I use are substantially non-combustible?
