From new openings to replacement joists and supported spans, GS Renovation carries out structural alterations throughout Soho and W1. Working in the area's bay-fronted Victorian and Edwardian terraces, with their rear closet wings and side returns, our team brings 30-plus years of structural experience to homes and upper-floor apartments across Westminster.
Structural alterations across Soho's terraces
The Victorian and Edwardian terraces around Soho throw up a broad range of structural work. Homeowners ask us to form new openings between rooms, widen a doorway into a supported opening, replace tired or overloaded floor joists in the closet wing, and occasionally underpin foundations where settlement has appeared over a century and a half of use. Each of these needs its own engineered solution rather than a one-size-fits-all approach.
We begin with a structural engineer who inspects the property, works out the loads and specifies the fix. A new opening gets a steel lintel or beam bearing onto padstones; replacement joists are sized for the span and grade; underpinning is designed and poured in sequenced bays so the wall above stays supported. Temporary propping holds everything in place until the permanent support is in and load-tested.
Consents and sign-off in Westminster
Because Soho's terraces share their flank and spine walls with the buildings either side, alterations that touch a shared wall, cut into it for a beam bearing or excavate alongside a neighbour's foundation for underpinning are notifiable under the Party Wall Act. We prepare and serve the notices on the adjoining owners in good time, which keeps relations calm and stops disputes stalling the works in a densely built W1 street.
Structural alterations inside the home are controlled under the Building Regulations, so Westminster City Council's building control inspects and certifies the steelwork, bearings, joists and any underpinning. Planning permission only enters the picture for exterior alterations in a conservation area or to a listed building. We coordinate the engineer, the party wall process and the building control inspections together, giving you one point of contact for the whole alteration.
