What we build
Our conversion services
Double garage
Convert all of it, or split it — half living space, half storage. Big enough for an open-plan family room or two smaller rooms.
Double garage conversionsHome office
Built for eight-hour days, not fair-weather use: insulation, heating, wired data and enough sockets to never think about it again.
Garage to home officeBedroom & annexe
Guest room, teenager's escape or an en-suite space for a relative — including the escape windows and fire separation the regs demand.
Garage to bedroom or annexe
Local knowledge
Built for Aylesbury's new estates
The integral garages on Kingsbrook, Berryfields, Buckingham Park and Fairford Leys share a secret everyone on those estates already knows: they're too small for a modern car. Most sit unused — a cold box holding bikes, boxes and the lawnmower, attached to houses where a family could genuinely use another room.
Converting one usually falls under permitted development, so no planning application is needed. But — and this is the part most builders won't tell you — some estates carry restrictive covenants in the deeds that say the garage must stay a garage, no matter what planning rules allow.
So we check both, for every enquiry, before we quote: your estate's covenant position and your home's permitted development status. If there's a snag, you'll know before you've spent a penny — and you'll know the route through it, because there usually is one.
Why we lead with the awkward stuff
A conversion that skips these checks can stall mid-build or surface when you sell. Telling you about covenants up front occasionally costs us a job. It's also why the jobs we do take on finish clean.
The process
From first visit to completion certificate
- Survey & covenant / PD check
We measure up, check floor levels and damp, and confirm your covenant position and permitted development status — before anything else.
- Fixed quote
An itemised written price covering drawings, materials, labour and fees. The number you sign is the number you pay.
- Building control application
We submit the application and deal with every inspection — you don't chase anyone.
- The build
Door infilled with matched brickwork, floor brought up level, insulation, electrics, heating, plaster and decoration — typically 2–3 weeks on site.
- Completion certificate
Building control signs the room off as habitable space. That certificate is what protects the value of the work when you sell.
The question everyone whispers
Does converting the garage lose value?
Almost never — as long as off-street parking remains. Most Aylesbury homes keep their driveway, and buyers value a warm extra room over cold storage. Where the garage is your only off-street space, we'll say so before you spend anything.

Where we work
Our service area
We convert garages across Aylesbury and the villages around it — Wendover, Princes Risborough, Stoke Mandeville, Aston Clinton, Haddenham and Weston Turville. Working within a short radius is deliberate: it's how we know which estates carry covenants, which streets have tight parking, and what local building control expects at each inspection. If you're just outside these areas, ask — the diary sometimes allows it.
Straight answers
Frequently asked questions
How much does a garage conversion cost in Aylesbury?
A single garage conversion to a dry room typically costs £12,500 – £17,500 around Aylesbury; add plumbing and it's £15,500 – £21,000. A double runs £19,500 – £32,000. Every quote we issue is fixed and itemised — drawings, building control fees and making-good included, no provisional sums.
Do I need planning permission?
Usually not — around nine in ten garage conversions are internal works covered by permitted development. The exceptions are conservation areas, listed buildings, flats, and estates where the original planning consent removed permitted development rights. We confirm your home's status as part of the free survey.
My estate has a covenant saying the garage must stay a garage. Is that the end of it?
No — but it can't be ignored either, because planning permission doesn't override a covenant. Most developers will consent to a well-designed conversion via an application and sometimes an admin fee; where consent isn't practical, an indemnity policy often covers the risk. We map the route for your deed before any work starts.
Are building regulations still required if planning isn't?
Yes, always. A habitable room must meet the regulations for structure, fire safety, insulation, ventilation, damp-proofing and electrics. Every project we do is inspected and signed off by building control, and you receive the completion certificate — the document your buyer's solicitor will ask for.
How long does it take?
Typically 2–3 weeks on site for a single garage, a little longer where we're adding plumbing or converting a double. Building control approval runs ahead of the start date, so the on-site programme is short and predictable — we'll give you the exact schedule with your quote.
