Garage Conversion in London
Convert your unused garage into a bedroom, home office, playroom, utility room or additional living space. Garage conversions are one of the most cost-effective ways to add usable floor area to your home — typically without planning permission.
Why a garage conversion makes sense
The average integral garage in London sits unused for years while families struggle for space. Converting it to a habitable room costs a fraction of an extension — because the structure is already there. You are adding insulation, a new floor, internal lining, windows, M&E connections, and a door from the house. That's it.
Depending on size, specification, and any structural changes required.
From mobilisation to completion on a standard integral garage conversion.
Integral garage conversions are typically PD — no planning application needed.
What a garage conversion typically includes
Note: all second-fix materials (flooring, light fittings, sanitary ware if adding WC) are client-supplied unless otherwise agreed.
Popular garage conversion uses
Ground floor bedroom
Ideal for elderly relatives, accessibility requirements, or simply creating an additional bedroom without a loft conversion. A ground floor double bedroom with en-suite is fully achievable in most single garages.
Home office
A dedicated, separate home office with proper insulation, power, internet connection, and natural light is one of the most popular post-pandemic garage conversion uses. More effective than working from a spare room.
Playroom / hobby room
A converted garage makes an excellent playroom or hobby space — kept separate from the main living areas, with its own access, easy-clean flooring and good storage.
Utility / boot room extension
Connecting the garage to the kitchen to create a utility room, boot room, larder or laundry space. Often combined with a structural opening into the house.
Gym or wellness room
A home gym requires proper flooring, good ventilation, and adequate power provision. A converted garage is the most practical solution — separate from the main house, robust enough for equipment.
Annexe or additional living space
With the addition of a bathroom and kitchenette, a detached or large integral garage can become a self-contained annexe — subject to planning for change of use in some cases.
Planning permission for garage conversions
Converting an integral garage (attached to the house) to habitable use is typically permitted development — no planning application required. However, planning permission may be needed if: your property is in a conservation area; the conversion changes the external appearance significantly; you are in an area where the original permitted development right has been removed. We check planning status before every project.
