What can you turn your garage into?
A garage full of bikes and boxes is often the easiest extra room in the house. The walls, roof and foundations are already there, so you gain living space without building outwards or losing garden.
Home Office
A quiet, insulated workspace away from the main living areas.
Utility & Boot Room
Often combined with a downstairs WC.
Playroom or Gym
Or a cinema room, with proper soundproofing.
WHAT AFFECTS THE COST?
Every garage is different, so we price each conversion individually after a free survey. You get a fixed, itemised written quote, with no surprises once work starts. The main things that shape it are:
Integral or detached
Detached garages often need more insulation, new services and sometimes planning permission.
Single or Double
The size of the space and how it’s split into rooms.
Floors & Walls
Floors usually need raising and insulating, and damp or weak walls add work.
Plumbing
Adding a WC, shower room or utility means new drainage and water supply.
Knocking Through
Opening into the house may need a steel beam and structural calculations.
Finishing & Fittings
Flooring, joinery, lighting and furniture, chosen in our showroom.
Do you need planning permission for a garage conversion?
Usually no. Converting an integral or attached garage is normally covered by permitted development, as long as the work is internal and the outside of the house doesn’t change much.
You will need planning permission if:
- your house is in a conservation area or is listed
- permitted development rights were removed when your estate was built
- you’re extending the footprint or changing the roofline
Building regulations approval
Building regulations cover insulation, foundations for the new front wall, damp-proofing, ventilation, fire safety and escape windows. We submit and manage the application, and hand you the completion certificate you’ll need when you sell.

Garage conversion FAQs
How long does a garage conversion take?
Most single garage conversions take [6–10] weeks on site, plus [2–4] weeks beforehand for design and building control.
Do you need planning permission for a garage conversion?
Usually not. Converting an integral or attached garage is normally covered by permitted development, as long as the work is internal and the outside of the house doesn't change much. Planning permission is needed if your house is in a conservation area or is listed, if permitted development rights were removed when your estate was built, or if you're extending the footprint or changing the roofline. Building regulations approval is always required.
Does a garage conversion add value?
Usually, because you add a habitable room without building an extension. On some streets parking matters more to buyers, and we'll tell you honestly if we think a conversion is the wrong move.
Can I stay in the house during the work?
Yes. Most of the work is contained in the garage, and the knock-through into the house is usually done in the final weeks.
Is my garage floor and wall suitable?
Most are. We check the floor level, damp and foundations at survey. Floors usually need raising and insulating to meet building regulations.
Do you convert detached garages?
Yes, into home offices, gyms, studios or annexes. If it's going to be a bedroom or annexe, planning permission is more likely to be needed.
How much does a garage conversion cost?
It depends on the size of the garage, the condition of the floor and walls, and whether you're adding plumbing or knocking through into the house. We give a fixed, itemised quote after a free survey.
Do I need an architect for a garage conversion?
You need drawings for building regulations. Our in-house architectural services team produces these as part of the project, so you don't need to appoint anyone separately.
Is a garage conversion or an extension better?
A garage conversion is usually quicker and less disruptive because the walls and roof already exist. An extension gives you more space overall but takes longer and more often needs planning permission. We can design and quote for both so you can compare.
