A single-storey rear extension is the classic way to give a Holland Park house the bright, garden-facing ground floor it was never built with — usually a kitchen-dining room that opens to the outside. It adds genuine living space without touching the street elevation, which is part of why it works so well in a protected area.
Because most of Holland Park is in a conservation area, permitted-development rights are restricted, so a rear extension needs a planning application and a design that respects the original rear elevation and the neighbours’ daylight and outlook. The depth, the roof form and the glazing all have to be judged against RBKC’s expectations.
We design the extension to suit the house and the garden, win the consent, engineer the structure and the opening back into the house, and build it through to a finished room — one contract from drawings to handover.
In a conservation area a rear extension is a planning exercise as much as a building one.
Conservation-area restrictions mean the extension needs a planning application, not permitted development.
Daylight, outlook and overlooking to neighbours shape the depth and the design.
The roof form, rooflights and glazed doors decide how light and how well-judged the room is.
Connecting the extension to the house means a structural opening, engineered and party-walled.
