The bulk of work on a loft conversion is structural, and a structural engineer is better for that work than an architect, if one can be found who does loft conversions.
| Dormer windows give a lot of extra space | Regulations that I have heard of so far: | You need a fire escape window on a 3rd floor (Velux do them) | there needs to be a 2m clearance from the top stair to the ceiling above. | Doors on the 3rd floor need to fire proof. (Special doors available with | wired glass or at least a coat of fireproof paint on a bog standard one)
AIUI all doors onto the staircase need to be fire resistant.
| If u are putting more than one habitable room (bedr or study etc, not bath) | , there needs to be a fire escape on the outside.
External fire escapes are generally unacceptable

A separate ring circuit, if it is required, is one of the easiest parts of the job and will not need a qualified electrician (in Scotland, the BCO may require to see a certificate as part of the Building Warrant application).
