Interior design & build · South East London
Interior design and build in South East London, under one roof.
We design kitchens, lofts, gardens and whole houses across South East London, then build them with our own team.
A design studio that builds
Most designers hand the drawings to someone else. Most builders never see the drawings. We do both, so the proportions, light and details that make a room feel right survive all the way to the last coat of paint.
One conversation, one contract, one team answerable for both the drawings and the finish.Nothing gets lost in the handover, because there isn't one.
Our specialism
Specialist kitchens, drawn and built by one team.
Kitchens are what we do most.We plan the room around the light and the way you cook.We make the larders and runs in our own workshop, and do the steels, plumbing, electrics and decoration ourselves.
Our other specialism
Bathrooms that are still right in ten years.
The part of a bathroom that decides whether it lasts is the part you never see.That means where the services run, how the room is tanked and how it is ventilated.We draw that first and tile last, and the plumbing and the electrics are done by our own people rather than a subcontractor.
Who does the work
Drawn in-house. Built by our own trades.
The studio draws it; our own builders, carpenters, plumbers, electricians, plasterers and decorators build it.One team, one foreman, one number to call.

Two alcoves, one wall of books
Full-height shelving either side of a restored fireplace, wired for reading lamps, painted to disappear into the wall.
Commercial interiors
Spaces that trade well, finished like a home.
Cafés, shops and small offices designed to bring people in and make them stay.The same team builds them, so the drawings survive the programme.

“They treated our little terrace like it was a magazine job.Every skirting, every hinge.And the kitchen came in on the number Colin gave us in week one.”
“We’d had three builders round.Colin was the only one who asked how we wanted the room to feel.Budget came second.”
“The shelves look like they were always there.Friends ask whether they were original to the house.”
