I don’t wish to circumvent any rules and will carryout all necessary regulations, just need a better understanding of what is and isn’t deemed acceptable without the need for planning but compliant with building control.

That’s all sounds good just out of interest what would make it non incidental to the house in other words to be seen as separate dwelling?

Hi, it’s in Devon.

OK so this is making sense 30 sqm or larger requires building control regs and from a planning perspective no more than 50% of the curtilage. My plan is for an internal space of 30sqm double pitched roof to 4meters , 2.5 m to the eaves and 2m from the boundary using non combustible cladding ie steel. Will a timber frame be acceptable sitting on insulated concrete pad? The room will primarily be used as a craft room studio but with occasional sleeping for guests using a wall bed. I will be adding a small sower room and separate composting loo. I imagine this will need further building regs ? Any pointers and advice would be welcomed.

Sorry just to add it will be 2meters from any boundary and timber construction on insulated concrete pad.

Thanks for that so building control says 30 square meters max otherwise? Is there a max re. permitted development on the planning side?

Hi all, This is my first post so bear with me. Planning a garden room and looking into permitted development rules as I don’t want to go through planning. With regards to dimensions am I correct in thinking that you can go to a max of 30sq meters internally without planning or is that a building control matter?
