G'day folks,
As I understand BR, if you build an outbuilding of 15-30m2 within 1m of of the boundary,
Then you are required to build the structure of primarily non-combustable materials to avoid needing a visit from your local BCO.
Question the first:
What is measured to the boundary to determine the position and it's subsequent effect on construction/BR requirement?
Is it boundary to the wall? To the roof overhang?
To the guttering? (i.e. The closest actual part of the building)
The specifics I understand is that the m2 size is the floorspace within the external walls,
It is straight-forward to make non-combustable walls, i.e. Brick and.block.
Question the second:
How do you make a non-combustable roof?
I think I've read somewhere that to make a conventional timber construction flat-roof considered non-combustable by BR, that it needs inches of crushed limestone - quite extreme construction.
I've also seen a fair few sectional garages with steel structure supporting cement fibre boards - this certainly won't light, is it therefore considered non-combustable?
What about a wooden structure supporting concrete tiles or such? Is that non-combustable?
A wooden structure supporting cement boards?
Question the third:
If a combustable (e.g wood and felt) roof if fitted, and BR involved, do they just check the fire barriers to prevent the roof catching or does the whole building then fall under BR control?
Yours,
Confused from Essex.
