Stud partition walls, floor joists, roof timbers and door linings, the structural carpentry that everything else is built on.
First fix is the structural carpentry stage, the stud walls, floor joists, roof timbers and door linings that go in before plastering starts.
Get this stage right and everything that follows, from a plumb wall to a door that hangs properly, is straightforward. Get it wrong and every later trade ends up fighting the same problem.
Non-structural and load-bearing partitions, built plumb and true.
Timber floor structures ready for insulation and floorboards.
Openings framed to the right size before the door goes in.
Structural timberwork for extensions, dormers and loft conversions.
