GS Renovation designs and builds extensions across Knightsbridge, working with the Georgian and Regency townhouses and mansion blocks that define SW7. With more than 30 years in the Royal Borough of Kensington and Chelsea, we handle groundworks, steel, roofing and full fit-out, and manage the planning and party wall side that comes with a conservation-area address.
Rear and side-return extensions in Knightsbridge
Many Knightsbridge houses have a rear closet wing and a narrow side return that can be infilled to widen the kitchen and bring in light. We start with foundations and groundworks suited to the ground conditions, then form new openings with steel beams sized by a structural engineer and signed off by building control. The roof, glazing and drainage are built to match the proportions of a period property rather than fight against them.
Because these homes are typically listed or within a conservation area, an extension in SW7 is far more likely to need a full planning application to the Royal Borough than to fall under permitted development. We are always honest about which route applies to your specific house, and we shape the design around what the council is likely to accept, so you are not chasing a scheme that will never be approved.
Planning and party walls in the Royal Borough
Whether an extension is permitted development or needs planning permission depends on the property, and in Knightsbridge the answer usually leans towards a formal application, especially where the house is listed or the elevation faces the street. We help you understand the difference between planning permission, which governs what you may build, and building regulations, which govern how it is built, so the two are never confused as the project progresses.
Extensions here almost always trigger party wall matters, because you are digging foundations near a neighbour or building up against a shared boundary in a tightly packed SW7 terrace. You serve the correct notices, work to the engineer's design and keep building control involved from foundations to completion. From first fix through to the final coat of paint, one team handles the full fit-out so the new space is finished to the standard of the house.
