Not sure how much a garage conversion should cost? You’re not alone. Google it, and you'll get answers ranging from £5,000 to £20,000, which isn’t very helpful when you’re trying to plan.
At Space Conversions, we believe in giving people a straight answer. This guide explains what goes into the cost of converting your garage, why quotes vary, and what to look out for when comparing prices.
What’s Included in a Basic Garage Conversion?
A standard conversion turns your garage into a liveable, regs-compliant room. That usually includes:
Full insulation and ventilation
New windows and wall where the garage door was
Flooring, electrics, plastering, and heating
Fire-rated internal access door
Certification to meet building regs
Our ‘Standard’ package starts from £12,500, fully itemised and fixed-fee.
What Can Affect the Garage Conversion Cost?
Not all garages are equal. Here’s what can increase (or decrease) your quote:
Whether the garage is integrated, detached, or part of a new build
Whether internal access needs to be created
The size and condition of the structure
Plumbing or partitioning requirements
Specification and finish levels
What’s Not Usually Included?
Some quotes won’t cover things like:
Planning permission (if required)
Painting and decorating
Custom fixtures like built-in storage or en-suites
At Space Conversions, we tell you exactly what’s included up front, and we’ll flag any add-ons during your free survey.
