Garage Conversion Types

What we convert your garage into

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.

FAQs

Garage conversion questions, answered

How much does a garage conversion cost in Truro?

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.

Do I need planning permission for a garage conversion?

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.

Do you cover areas outside Truro?

Yes — we cover Truro and a wide area of Cornwall including Falmouth, Redruth, Newquay, St Austell and the villages in between. See our full areas covered page, or give us a call to check.

Is Wren Builders Ltd a registered company?

Yes. Wren Builders Ltd is VAT registered and has been trading since 2016, with a full Checkatrade profile showing our vetting checks, reviews and company details.
