Garage Conversions
Garage Conversions in Hertfordshire, Bedfordshire & Cambridgeshire
If your garage is used for storage rather than the car, it’s wasted living space. LJT Construction has been converting garages into playrooms, home offices, gyms and extra bedrooms across Hitchin, Bedford, Cambridge and the surrounding areas for almost 20 years. Every garage conversion is designed and built by our own team.
Garage Conversion Specialists
A garage conversion is one of the most cost-effective ways to add usable living space, because most of the structure — walls, roof and foundations — is already there. Whether you want a playroom, a home office, a gym, or an extra bedroom, we handle the insulation, damp-proofing, flooring and finishing needed to turn a cold storage space into a proper room, from design through to the final coat of paint. If the garage needs to stay a garage, a loft conversion is often the next best way to add a room.
Types of Garage Conversion
Full Conversions
Converting the entire garage footprint into a single room — a playroom, snug, or home office — with the existing garage door replaced by matching brickwork and a window.
Partial Conversions
Garage-to-Bedroom Conversions
Adding an extra bedroom, often with an en-suite, by fully insulating and reconfiguring the space — useful for growing families or creating a ground-floor bedroom for accessibility.
Home Office and Gym Conversions
Fitting out the garage with proper insulation, power and lighting for a dedicated space to work or train from home, away from the noise of the rest of the house.

Do You Need Planning Permission?
Most garage conversions don’t require planning permission, since they typically don’t change the building’s footprint or roofline, provided the work is internal and the garage isn’t separate from the main house. Building Regulations approval is always required, particularly for insulation, damp-proofing, fire safety and electrics. We’ll assess your property at the free survey stage and handle any applications on your behalf. For the official rules, see the Planning Portal guidance on garage conversions.
FREQUENTLY ASKED QUESTIONS
How long does a garage conversion take?
Most garage conversions take 3 to 6 weeks, depending on the size and whether plumbing or an en-suite is involved. We’ll give you a clear timeline before work begins.
Will the converted room be cold like the garage was?
No — a proper conversion fully insulates the floor, walls and roof, so the finished room performs like the rest of your house, not like a garage with a rug in it.
Do I lose parking if I convert my garage?
You lose the garage as covered parking, though the driveway in front typically remains usable. If off-street parking is a concern, we’re happy to talk through the trade-offs at the survey stage.
How much does a garage conversion cost?
Cost depends on the size of the garage and how the new space will be used — a simple playroom costs less than a bedroom with an en-suite. We provide a detailed, no-obligation quote after a free site survey.
