Carpentry runs through a build like a spine: the trusses that shape the roof, the studwork that divides the rooms, the doors and skirting that finish them, and the fitted pieces that make a house feel bespoke. It is one trade wearing four hats, and the quality of each hat shows for decades.
Mitchell & Andrew Building Services carries carpentry and joinery through every stage across Truro projects, and this is what each layer involves.
Structural: the frame that shapes everything
The photograph on this page is carpentry at its most structural: trussed rafters landing on a timber frame, the roof's geometry set in an afternoon. Structural carpentry, floor joists, roof structures, steel-and-timber marriages, is engineering executed in wood, cut and fixed to drawings rather than eye.
Precision here is compound interest: a frame square and level makes every later trade faster and every finish straighter. The spirit level used on day ten saves the scribing plane on day ninety.
- Trusses, joists and frames set the building's geometry.
- Fixed to engineered drawings, not instinct.
- Early squareness pays every later trade.
First fix: rooms take shape
First fix carpentry happens while the building is still bones: stud walls framing the room plan, door linings set plumb, floors decked, window boards fitted, and the noggins and backing that later fixtures will secretly rely on, radiators, rails, wall-hung furniture all hang on wood placed now.
The invisible discipline is thinking ahead: a noggin behind future grab rails, backing where the television will hang, access panels framed where services will need reaching. Mitchell & Andrew Building Services first-fixes with the finished room in mind, because retrofitting backing into closed walls is misery.
- Studwork, linings, decking: the room's skeleton.
- Everything plumb and level before boarding hides it.
- Noggins today where fixtures hang tomorrow.
Second fix: the visible centimetres
Second fix is where carpentry becomes what owners actually see: doors hung to even margins, skirting and architrave mitred tight, window boards and thresholds finished, stairs balustraded. These are the centimetres people run their eyes and fingers along for the life of the house.
The standard is unforgiving because the sightlines are long: a hallway shows every door margin at once. Gaps caulked into submission read as exactly that; joinery cut right reads as calm.
The bespoke layer
Beyond the standard fit sits the layer that makes houses individual: alcove cupboards and shelving built to the room's real dimensions, panelling and wainscot, window seats, understairs storage that uses every awkward centimetre. Off-the-shelf furniture ignores old walls; bespoke joinery is scribed to them.
This is also where builder and joiner being the same firm pays: the alcove unit lands on studwork placed for it, cabling arrives inside it pre-planned, and decoration follows as one sequence. Bespoke work bolted onto a finished room costs more and fits worse than bespoke work grown inside the build.

Questions customers ask
What is the difference between first fix and second fix carpentry?
First fix is the hidden structure before plastering: studwork, linings, floors, backing. Second fix is the visible finish after: doors, skirting, architrave, stairs parts. Both are the same trade at different reveal levels.
Can you build fitted furniture into old alcoves?
Yes, and scribing to the real walls is the entire point: bespoke units follow the room's true lines where flat-pack fights them. Alcove cupboards and shelving are the classic case.
Why does door margin evenness matter so much?
Because hallway sightlines show every door at once and hands touch doors daily: uneven margins broadcast rushed work forever. Even margins are the quiet signature of careful carpentry.
Frame square, first fix thoughtful, second fix tight, bespoke where the house deserves it: carpentry done as one continuous craft is what quality feels like underhand.
