Which garage conversion is right for your home?
Start with how you want to use the room and what you still need to store. At a site visit, we assess the existing floor, walls, roof, access and services before agreeing a practical specification.
Partial garage conversion
A separate usable room while retaining part of the garage for bikes, tools or household storage.

Built to Last.
We're not a call centre with subcontractors. JB Garage Conversions is a hands-on team of skilled tradespeople who take personal pride in every conversion we complete.
Full Project Management
From planning checks to final snag — we handle everything so you don't have to.
Transparent Pricing
No hidden costs. We provide a detailed written quote before any work starts.
Building Regulations Managed
Garage conversions into habitable space normally require building-regulations approval. We can prepare the application and coordinate inspections where included in your quote — you pay council or registered building-control fees directly.
Minimal Disruption
We work efficiently and cleanly, respecting your home and your family's routine.
Ten-Year Business Guarantee
Our ten-year guarantee is provided by our own business, not an insurer. Ask for the written coverage, conditions and exclusions with your quotation.
Clear Written Contracts
We provide a clear written contract for your protection — setting out our commitment to complete the project, with a defined schedule and payment structure.

Our case studies show the existing garages, construction stages and finished spaces. Use them to discuss the layout and finish you would like—not as a promise that every garage needs the same work.
Chelmsford partial conversion
A useful new room with storage retained in the remaining garage.
