Single-storey, double-storey, rear, side-return or wrap-around. An extension is the surest way to get the kitchen-diner or extra bedroom a growing family needs without the cost and upheaval of moving in West London. Convert Extend designs and builds the whole thing, tied properly into the existing house and matched to the original brick.
Scope scales with the project, but these areas are the spine of any house extensions job with Convert Extend.
The classic rear extension that turns a cramped galley kitchen into an open-plan kitchen-diner, usually with bifolds or sliders onto the garden and rooflights overhead.
West London Victorian terraces hide a useful strip of dead space down the side return. Filling it in, often wrapping round the back, transforms the ground floor footprint.
Where you need a bedroom and bathroom as well as ground-floor space, a two-storey extension delivers both in one build, with the upper floor tied into the existing roof.
Removing the back wall to open the new space into the old needs proper structural steel and building control sign-off. We design the openings so the finished room flows as one.
It depends on size, ground conditions and finish, but most West London rear extensions land in a predictable range per square metre. We give you a clear written quote after the site visit, not a vague figure over the phone.
Smaller rear extensions often fall under permitted development, but conservation areas, larger footprints and two-storey work usually need full planning. We handle the drawings and the application either way.
A single-storey rear extension typically takes 12 to 16 weeks from breaking ground to handover. Two-storey and wrap-around builds run longer. You get a programme with dates up front.
