i know all bout fitting the joists etc , i dont need velux windows , and as its a dormer , on a bungalow , with 2 large double windows front and rear , that sorts external fire regs,

ive been reading the regs etc , on all the building work needed , ive no trusses ,


so you reckon that a loft is a bigger job than an external brick extension ???
im no pro builder , but can do enough , just not had a massive experiance in loft conversion


do they use any steel rsj's for the dormers ??

and about 20k is the norm then ???
