Your Questions, Answered.
We know that planning a home conversion or renovation can raise lots of questions. To help make things clearer, we’ve put together some of the most common queries our customers ask.
What kind of spaces do you convert?
We transform garages, lofts, conservatories, and spare rooms into functional spaces like offices, playrooms, gyms, or guest suites.
Do you offer free quotes?
Yes, we provide free, no-obligation quotes following a quick site visit and chat about your plans.
Will my project meet building regulations?
Absolutely. All work meets UK building regulations, and we can manage approvals for you.
Do I need planning permission?
In most cases, no. Many conversions fall under permitted development — we’ll confirm this for your home.
How long does a conversion take?
Garage conversions usually take 2–4 weeks; lofts 4–8. We’ll give you a clear timeline before work begins.
