Rooflight (Velux)
No change to the roofline — windows sit flush in the existing slope. The most affordable route, if you already have the head height.

What we build
Types of loft conversion
Dormer
A box built out of the roof slope to create real head height and usable floor area. The most common way to get a proper bedroom up there.
Hip-to-gable
Squares off a hipped roof to unlock volume that's otherwise wasted. Common on semis and end-terraces.
Structure, stairs & fire safety
Steels, floor build-up, a compliant staircase and a certified escape route. This is the part the wrong builder skips.
Straightforward to work with
How a SwiftBrick project works
1. Plans, or no plans yet
2. Site assessment & detailed quote
3. Professional build, personally managed
4. Building Control sign-off & handover
Site assessment & detailed quote. Every quote is based on a personal site visit from Luke and a proper look at your plans. No vague estimates, no surprise extras. If there's a realistic possibility of additional cost, it's flagged upfront — not sprung on you halfway through.
Professional build, personally managed. Your project is managed on site by a Chartered professional, supported by a hand-picked team of experienced tradespeople. You get a direct number. The job runs to programme — or you're told why.
Building Control sign-off & handover. We don't call a job finished until Building Control has signed it off. You get a full debrief, the documentation, and an insurance-backed guarantee.
No plans yet? Luke offers a paid pre-construction site visit and consultation for a nominal fee — feasibility and honest advice before you commit serious money.
Good to know
Common questions
Do I need planning permission?
Many loft conversions are permitted development, but dormers and hip-to-gable alterations can need permission depending on volume and location. We'll tell you before you spend money on drawings.
Does it need Building Control sign-off?
Always. Structure, fire escape, insulation and staircase geometry all have to be certified. It isn't optional, and it's what protects you when you come to sell.
What does a loft conversion cost?
We price loft conversions at £1,800–£2,600 per m². A rooflight conversion typically starts around £25,000. Dormer and hip-to-gable conversions run higher because of the structural work involved. You get a fixed written quotation after a site visit — not a range.
Do I have enough head height?
As a rule of thumb you want around 2.2m from floor to ridge before conversion. It's the first thing Luke measures — and if it doesn't work, you'll be told straight away.
How long does it take?
Most conversions run six to ten weeks, depending on type and complexity.
