FAQs – Garage Conversions

Do I need planning permission to convert my garage?
In most cases, no — garage conversions fall under permitted development rights. We’ll advise you if any specific permissions are needed for your property.

Will the new room be warm enough?
Yes — we fully insulate walls, floors and ceilings to meet modern standards, making the space comfortable all year round.

Can you add windows and doors?
Absolutely — we can replace the garage door with a wall and window, or install new doors as part of the layout.

‍How long does a garage conversion take?
Most garage conversions take between 3 and 6 weeks depending on the size and specification.

‍Can you still leave some storage space?
Yes — we can design partial conversions to keep part of the garage for storage if needed.
