Can anyone help here please.
I've decided to do my own plans and have got through planning ok but have a couple of exceptions on building regs. Would appreciate any help.
We are building a flat roof extension to lounge about 4M square.
1.Ventilation.
a) method of acieving cross ventilation to flatroof void for a cold roof.
b)minimum 8000mm2 of background ventilation is reqd ??
clarify how reqd levels of ventilation are to be maintained in lounge.
2. preventing cold bridging at flat roof eaves.
3. Energy efficient lighting please specify type.
4. method of preventing cold bridging at masonry abutment between new and existing walls.
Thanks for help
