Structural alterations in Putney call for a builder who understands SW15's Victorian and Edwardian stock. GS Renovation forms new openings, replaces failing joists, underpins weak foundations and installs supported openings across the neighbourhood's bay-fronted terraces and riverside homes. With 30+ years of structural experience, we design each alteration around an engineer's calculations and get it signed off properly.
Structural alterations for Putney's period homes
The side return and rear closet wing common to Putney terraces are where most structural alterations happen: a new steel-framed opening into a side-return extension, a wider doorway between kitchen and dining space, or a replacement lintel over a tired opening. Each new opening needs an engineer to size the beam or lintel, and each needs padstones and temporary propping while the masonry above is unloaded and the steel is set.
Older Putney homes also throw up joist and foundation work. Bouncing floors near the bays or over the closet wing often mean undersized or rotten joists that we replace and correctly bear. Where movement or a nearby tree has affected the shallow Victorian footings, we underpin in short, hit-and-miss bays to an engineer's design, taking the foundation down to firm bearing without undermining the wall above.
Engineered and certified in Wandsworth
Supported openings, replacement joists and underpinning are all controlled work under the Building Regulations, so Wandsworth Council's building control inspects the key stages and issues the completion certificate. We handle the notice and the inspection bookings, exposing padstones, bearings and underpinning bays for the inspector at the right moment. Internal structural alterations do not need planning permission; that only applies to exterior changes in a conservation area or on a listed building.
Because Putney's terraces are joined to their neighbours, alterations that touch the shared party wall, cutting in a beam, underpinning up to the boundary or forming an opening in it, are notifiable under the Party Wall Act. We flag which parts of your project trigger the Act, serve notice on the adjoining owner, and coordinate the schedule of condition so both households are protected before the first prop goes up.
