From home offices to granny annexes, Wren Builders Ltd turns unused garages into warm, genuinely usable rooms — done properly, from insulation up.
Vetted & VAT registered
Fully insulated to current standards
No-obligation quotes
Based at Penstraze since 2016
Every conversion starts with the same solid groundwork — insulation, damp-proofing and Building Regs compliance — then we shape the room around how you'll actually use it.
A look at the standard of finish we build to — real Wren Builders jobs, not stock photography.
Harry visits in person to assess your garage's construction, discuss what you want the space to become, and talk through what's realistic.
You get a straightforward, no-obligation quote — no vague allowances, no surprises further down the line.
Floor, walls and roof brought up to current standards first, then first-fix electrics, plumbing and finishing.
A finished room you can actually use, with everything explained before we shake hands and leave you to enjoy it.

Costs depend on the size of the garage, its current construction, and what the room will be used for — a home office conversion is typically simpler than an annexe with its own bathroom and kitchenette. We provide a free, no-obligation estimate after seeing the garage in person.
Most garage conversions fall under permitted development rights, provided you're not extending the building's footprint. Building Regulations approval is still required for any change of use, since the space needs to meet current standards for insulation, fire safety and ventilation.
