From new openings to underpinning, GS Renovation carries out structural alterations across Holland Park's W11 villas and period terraces. With over 30 years of building experience in the Royal Borough of Kensington and Chelsea, we form supported openings, replace tired joists and strengthen foundations, always to a structural engineer's design and signed off under the Building Regulations.
Structural alterations for Holland Park's period homes
Holland Park's bay-fronted Victorian and Edwardian terraces present a familiar set of structural jobs: widening a doorway between rooms, forming a new supported opening into the side return, or replacing floor joists softened by decades of damp beneath the closet wing. Each one changes how load travels through the building, so we start with an engineer's assessment rather than guesswork about what the existing structure is quietly holding up.
Where a fresh opening is cut into a supporting wall, a correctly sized steel beam carries the masonry above and bears onto padstones at each end. Replacement joists are specified to span the room and match the existing floor levels. Every alteration is temporarily propped, taken apart in controlled stages and reassembled so the load path is continuous and sound before we ever release the supports.
Underpinning and consents in the Royal Borough
Some W11 properties, particularly older villas near Holland Park itself, show settlement or need deeper foundations before a basement or extension. We underpin in short, engineer-designed sequential bays so the building stays supported throughout, pouring each section before moving to the next. It is patient, methodical work, and in a densely built street it demands care for the neighbouring foundations as well as your own.
Structural alterations are controlled under the Building Regulations, so the Royal Borough of Kensington and Chelsea's building control inspects and certifies the work, not a planning department. Where the alteration touches a shared party wall or affects an adjoining foundation, the Party Wall Act applies and we serve notice first. Planning consent is only relevant for external changes on listed buildings or within a conservation area.
