From new openings to replacement joists and supported spans, GS Renovation carries out structural alterations throughout Wallington's Victorian and Edwardian terraces. Over 30 years working across SM6 and neighbouring Carshalton and Sutton, we have handled the awkward closet wings, side returns and tired timber that these period homes throw up, always with an engineer's design behind the work.
Structural alterations for Wallington's period homes
The terraces around Wallington and towards Cheam share common quirks: rear closet wings that homeowners want opened up, side returns waiting to be brought into the kitchen, and original floor joists that have sagged or been notched by generations of pipework. Each alteration, whether a new supported opening or a run of replacement joists, needs an engineer to confirm sizes and bearings before we cut into anything.
New openings are formed with a correctly sized steel beam bearing onto padstones, temporary props holding the structure while we work, and staged demolition so loads are never left unsupported. Replacement joists are specified to span and grade, and where ground movement or an inadequate footing is found, underpinning is designed to stabilise and support before the alteration above it goes ahead.
Consents and building control in Wallington
Internal structural alterations in Wallington are governed by the Building Regulations, so Sutton Council's building control inspects the beams, bearings and any underpinning and issues the completion certificate. This is not a planning matter. Planning or listed-building consent only comes into play for exterior changes in a conservation area or to a listed building, and we will tell you clearly if your address falls into that category.
Because these SM6 terraces share a party wall and often shared chimney stacks with the neighbours, many alterations are notifiable under the Party Wall Act. You serve the notices, coordinate any award, and keep a record for your files. From the engineer's drawings to the final sign-off, you deal with one team that owns the whole process.
