GS Renovation carries out structural alterations across Twickenham, from new openings and supported doorways to replacement joists and underpinning. The area's Victorian and Edwardian terraces, with their rear closet wings and side returns, throw up all sorts of structural puzzles, and 30+ years of experience in TW1 means we have solved most of them before.
Structural alterations for Twickenham homes
Whether you want a wider opening between two rooms, a replacement lintel over a new doorway or fresh joists under a sagging floor, each alteration in a Twickenham terrace starts with our structural engineer establishing what is being carried. New openings in solid brick walls are formed with a steel beam or lintel sized for the span, bearing onto padstones and propped while the work is done.
Older TW1 properties near the river sometimes show movement in original foundations, and where an engineer confirms it, underpinning deepens and strengthens the footings in carefully sequenced bays. Tired Victorian floor joists, especially in rear closet wings, are replaced or strengthened to modern spans. Every alteration is designed first, then built to that design, so nothing is left to guesswork.
Consents and sign-off in Twickenham
Structural alterations are governed by the Building Regulations, so Richmond Council's building control inspects the beams, lintels or underpinning at the key stages and issues the completion certificate. This is separate from planning permission, which only applies to exterior work in a conservation area or to a listed building. We make that distinction clear from the outset so you know exactly what is needed.
Where an alteration affects the party wall shared with a neighbouring Twickenham house, whether cutting in a beam or underpinning near the boundary, the Party Wall Act applies and we serve the correct notices in good time. Coordinating the engineer, the notices and building control under one roof keeps the job moving and spares you chasing separate trades around TW1.
