That dark space above your landing is a bedroom waiting to happen.
Rear dormers, hip-to-gables and mansards across South East London. You see every line of the price before you sign, and the person who surveys your loft is the person who runs the build.
âI survey every loft myself and Iâm on site every week of the build.â

See your loft, and what it costs, before anyone visits.
Pick your house and the loft you have in mind. The drawing redraws your roof, and the price splits into every line we would charge you for. Guide prices include VAT, design fees and Building Control.
Moving for one more bedroom costs money you never see again.
Stamp duty, agents and solicitors add nothing to your next home. A loft puts the same money into the house you already love. Compare the two with your own numbers.
- Higher price of the new home£0
- Stamp duty on the new home£0
- Estate agent to sell yours (1.5% + VAT)£0
- Solicitors, surveys and removals£5,000
- Midpoint of your loft guide price, VAT included£0
Orange is money spent on moving that stays with HMRC, agents and solicitors. Stamp duty uses the standard rates for England from 1 April 2025 for someone moving home. Agent and legal costs are typical figures, not quotes. This is a rough comparison, not financial advice.
Nine weeks from dust to daylight.
Drag across the photo. On the left, a loft as we usually find it: loose boards, bare brick and old pipework. On the right, the same footprint once it is a room.
- New steel beams and floor joists, signed off by a structural engineer
- Insulated to current Building Regulations, so it is warm in winter
- Fire doors, mains smoke alarms and a proper staircase
Finished lofts
From first visit to keys back, in six steps.
Free survey
Tom measures your head height, checks the roof structure and looks at where the stairs can land. You get a fixed, itemised quote within three working days.
Day 1Drawings and engineering
Our architectural designer draws the loft, and a structural engineer specifies the steels. You sign off the layout before anything is ordered.
Weeks 1â3Permissions and neighbours
We apply for a Lawful Development Certificate or planning permission, appoint Building Control and serve party wall notices. We knock on your neighboursâ doors first.
Weeks 3â10The build
Scaffold goes up and most of the work happens from outside, so you live at home. The ceiling below is only opened in the last fortnight to fit the stairs. Every Friday you get photos of the week and an updated payment tracker.
6â11 weeksSign-off
Building Control inspect at each stage. You receive the completion certificate, electrical certificate and your 10-year insurance-backed guarantee.
Final weekAftercare
We come back at six months to fix any settlement cracks in the plaster, free. Most clients never need us, but the visit is booked anyway.

What you pay for, and when you pay it.
Loft quotes are hard to compare because builders leave things out. Here is everything inside our price, and a payment schedule that never puts you ahead of the work.
Included in every quote
Stage payments
| Stage | Share |
|---|
The deposit is 5%, never a third up front. The final 10% is only due once Building Control have issued your completion certificate.
Not included: moving furniture and decorating the rest of the house. If a party wall surveyor is needed, their fee is quoted separately.

âWe stayed in the house the whole time. The scaffold went up on a Monday and by the Friday the roof was already open from outside. The stairs were the only messy week, and they told us exactly which week it would be.â
âThree other quotes were vague about Building Control and party wall. Haldenâs had both as separate lines with the actual fees. The final bill matched the quote to the pound.â
âTom spotted that our old purlin was split before anyone else did and sorted it in the design. Our daughter has the best room in the house now and the neighbours keep asking for his number.â
