A portfolio you can walk through
Every project below was designed, managed and finished in-house. A few recent completions across the region.
Chiltern Ridge
Glazed kitchen extension
A six-metre rear extension with a roof lantern and full-width bi-folds, opening a dark galley kitchen onto the garden.

A full kitchen strip-out and rebuild: inky shaker units, a honed stone island and concealed services, all set in two weeks.
Henley Hill
Dormer loft suite
A dark unused attic turned into a light-flooded master suite with twin rooflights, a dormer and a compact en-suite.
Beaconsfield
Full re-roof & dormer
A failing roof stripped back and rebuilt with clay tiles, new flashings, a matched dormer and warm copper rainwater goods.
How we work
A build without surprises
The same five steps on every job, from a thirty-minute call to the day we hand back your keys.
Consultation
We visit, measure and listen. You leave with an honest view of what is possible and a rough budget band.
Design & quote
Drawings, a fixed written quote and a dated programme. No provisional sums hiding in the small print.
Approvals
We handle planning, building control and structural calcs, so the paperwork never stalls your start date.
Build & finish
One site manager, a clean site and weekly updates. Snags are closed before we call it done.
Our promise
Backed in writing, not words
Peace of mind is part of the price. Every project carries the same protections, set out before you sign.
Ten-year structural warranty
Insurance-backed cover on every structural element we build, transferable if you sell.
Fixed-price contracts
The number we quote is the number you pay, barring changes you ask for in writing.
Dated programme
A completion date in the contract, with a credit if an in-house delay pushes it back.
Accredited trades
Gas Safe, NICEIC and FMB-registered trades on every project, references on request.
