RESIDENTIAL / LOFT CONVERSIONS

Turn the roof space into the best room in the house.

Dormer, hip-to-gable and rooflight loft conversions — a new bedroom, en-suite or studio, designed to work with your roof and built without the drama.

01 — IS THIS YOU?
  • “We need another bedroom without moving house.”
  • “Is our roof even tall enough?”
  • “We want a proper suite, not a cramped box room.”
02 — WHAT’S INVOLVED

The head height and the roof type decide the design: a rooflight conversion where the volume already exists, a dormer where it doesn't, hip-to-gable where the roof shape allows more. Most loft conversions fall under Permitted Development — we survey, tell you straight whether yours converts, and design to make the stair land properly rather than eating a bedroom below.

Fire regulations, structural design and building control are all part of the package — and the same team builds it.

03 — WHY SET SQUARE
  • We survey and tell you honestly whether it converts before you spend anything.
  • The stair position — the thing that makes or breaks a loft — is designed, not improvised.
  • Structure, fire strategy and building control handled in-house with the build.
04 — PROOF

Our residential case studies are being written up. In the meantime, the commercial and heritage projects show how we work when it’s genuinely difficult — the same care applies to a kitchen extension.

05 — QUESTIONS WE’RE ASKED
Will my loft convert?

Most will; head height and roof type decide the design. We survey and tell you straight — including when the answer is no.

Dormer or rooflight?

It depends on the space you need and the planning position. We'll show you both options at design stage with honest costs for each.

Do I need planning permission?

Usually not — most loft conversions fall under Permitted Development, within limits on volume and appearance. We confirm your position before any work starts.
