Maximising Useable Height in Block & Brick Garden Room

[Kalibre46]

When i built mine, I used a kind of home made SIPS system that i made and pre treated befor assembly. Then all i needed to do was mastic the joints and screw edge batten over them, as the panels were secured from inside. It was a tight squeeze but worked. The problem you have however is size. anything over 15m2 has to conform to the non-combustible rule.

Thanks. The size definitely brings in some challenges.

I've heard this, but wasn't sure if this was an official written or unwritten rule, or simply down to the individual building control officer being prgamatic. Any ideas? I'd hate to commit to a design building this advantage in only to find they say no.

It's an official rule. If you're concerned, you can have the arguments all up front by applying for a lawful development certificate. After that they can't complain.

I didn't know that this existed, very interesting! I will have to do some digging (figuratively and literally).

Or just apply for planning and then no need to worry about anything.

Such a large building at under 2.5m will have a awkwardly low ceiling if nothing else. Remember for proportion the ceiling height should increase with room size.
