Brick shed planning permission

Phone up your local council's planning department. They'll tell you for free.

Look it up on your own council website, some have information on there. Different councils have different rules.

not an expert but that sounds like an extension to me. what you use the space for is your choice. But what happens in future if someone wants to put a door in from the main house or build on top of it? I suggest you may need 2 metre footings.

Always good to check, however my understanding is that this would be classed as an out building and therefore no permission will be needed. Only if you had direct access to the house would it become an extension.

Sadly there is no universal answer here - you need to consult your local planning office.
I can tell you my dad built a "shed" - it was made from breeze block and plumbed! He clad the outside and when the inspector came out he ticked the box as from the outside it looked like a garden shed!Probably not the best picture, but the wall at the red arrow is actually a side wall of that "shed", my dad decided to use that wall as part of the building to save having to build a second wall. So the shed is actually not rectangular...

As others have said look at your local authority's website - might need building regs though?

ok thanks for all the help
