GS Renovation carries out structural alterations throughout Hounslow, working on the Victorian and Edwardian terraced stock that fills Chiswick, Brentford and Isleworth. Across 30-plus years in TW3, TW4, TW5, TW7, TW8 and W4 we have formed new openings, replaced tired joists, underpinned settled walls and installed supported openings, always to an engineer's design and signed off under the Building Regulations.
Structural alterations for Hounslow period homes
The bay-fronted terraces and Edwardian villas around Osterley Park and Syon Park often need more than a single knock-through. We form new openings between a kitchen and the rear closet wing, replace joists softened by decades of damp, and install supported openings where a doorway is widened into a genuine structural span. Each of these is designed by a structural engineer, not guessed at on site.
Older homes near the river at Brentford sometimes show signs of movement, and here underpinning may be the honest answer. Where foundations have settled we work to the engineer's scheme, excavating and pouring in sequenced bays so the wall is never undermined. Every steel we introduce bears onto padstones sized for the load, propped temporarily and released only once the new support is fully bedded.
Consents and sign-off across Hounslow
Internal structural alterations are controlled under the Building Regulations rather than planning, so Hounslow Council's building control is the body that inspects and certifies the work. Planning permission only enters the picture for exterior changes in a conservation area or to a listed building, which matters near Chiswick House, so we tell you plainly which route your project actually needs before you spend on the wrong application.
Where an alteration touches the party wall shared with a neighbouring TW7 or W4 home, the Party Wall Act applies and we serve the required notice in advance. We coordinate the engineer's calculations, the notices and the building control inspections as one package, book each stage at the right moment and hand over the completion certificate at the end.
