Converting a garage in Kensington & Chelsea
In England, converting a garage into habitable space will normally need approval under the Building Regulations. Planning permission is not usually needed if the work is internal and does not enlarge the building, but some homes have had permitted development rights removed, and new estates, conservation areas and listed buildings can have extra rules. Check with Royal Borough of Kensington and Chelsea before you start.

Why people in Kensington & Chelsea are converting their garage
More room without moving
A garage conversion adds a usable room to the home you already have, without the cost and upheaval of moving.
Uses space you already own
The walls, roof and base are already there, so a conversion can be less disruptive than building an extension.
A room for any use
Home office, bedroom, playroom, gym, utility room or a space for an older relative: the layout can suit how your household lives.
Warm, dry and comfortable
Floors, walls and the old garage door opening are insulated and damp-proofed, so the room is comfortable all year.
Built to the regulations
Conversions are normally inspected by building control, and a completion certificate shows the work meets the standards.
Managed by one builder
A vetted, accredited builder can coordinate the structural, electrical, plumbing and finishing work, with a clear quote up front.

Garage conversion questions in Kensington & Chelsea
Do I need planning permission to convert a garage in Kensington & Chelsea?
Often not, when the work is entirely internal. But it depends on your property: some homes have a planning condition that keeps the garage or its parking, and conservation areas, listed buildings and flats have extra rules. Ask Royal Borough of Kensington and Chelsea before you start, and consider a lawful development certificate if you want proof.
Will I need Building Regulations approval?
Normally, yes: turning a garage into a habitable room is controlled work. Building Regulations approval covers things like the structure, the new infill wall, floor and wall insulation, damp-proofing, ventilation, fire safety and electrics. Your builder should explain who applies and when inspections happen.
What happens to the garage door?
It is usually removed and the opening is filled with an insulated wall, often with a new window, so the room looks like part of the house. External changes may need planning permission, which is another reason to check with the council first.
Where will I park?
Think about this before you commit. If the garage is your only off-street space, work out where the car will go, and whether a driveway can still be used, because a planning condition or local parking rules may be involved.
Can I rent out or live separately in the converted garage?
Creating a separate home, even for family, can need planning permission whatever work is carried out, and a self-contained annexe has its own rules. Tell your builder and the council what you intend before design begins.
