01 — What we do

We put the
structure up.

Every building has a stage where it is nothing but timber and sky. That is the part we do — the frame, the roof, the studwork and the cladding that everything after us is fixed to. Get it right and the rest of the trades walk straight on.

02 — What we take on

The schedule.

Whole roofs, first and second fix, or a team on your programme for as long as the structural work runs. We work for builders, developers and homeowners.

01

Hand cut roofs

Cut and pitched on site — hips, valleys, dormers and anything a truss won't do. Marlow, Radlett, Rickmansworth.

02

Truss roofs

Set out, craned in, braced and decked. Full plots and terraces, to programme.

Truss roof run
03

First fix

Joists, studwork, floors, roof structure and everything that has to be right before it's covered in.

First fix joists and floor structure
04

Second fix

Doors, linings, skirting, architrave, stairs — back on site once the plasterer is out.

Second fix openings and linings
05

Cladding

Timber and composite cladding, battened and fixed over breather membrane.

07

Loft conversions

Start to finish — structure, dormers, Velux, insulation, stairs and second fix.

03 — Roofs

Hand cut,
or trussed.

Two different jobs, and we do both. Which one suits depends on the shape of the roof, the access and what the drawings ask for — happy to tell you which way we'd go.

Hand cut

Every rafter marked out and cut on site. It's the slower way and it takes a carpenter who can set out a roof properly, but it will follow any shape a building throws at it — hips, valleys, unequal spans, tying into something that's already there.

Trussed

Designed off the drawings, delivered to site and craned in. Far quicker over a plot or a terrace, and the right answer when the roof is a straightforward shape and the programme is tight. Set out, braced, decked and left ready.
