They are the building regs side of an architects. Been established for years, and planning side was perfect. Building control picked up a mass of mistakes, relating to insulation, fire, etc, they didn't give me a list, just said there were thirteen mistakes. Theses are now resolved, but where he told me I had to have gas boilers, I'm fine with electric, and was told I needed it to be timber framed, which is only 100x50mm, which no one even wanted to built, turns out I'm fine with brick and block, which is what I wanted. Just can't trust what he says.
