GS Renovation carries out structural alterations across Balham, the sort of work bay-fronted Victorian and Edwardian terraces so often need: new openings, replacement joists, supported openings and underpinning. With over 30 years in SW12, we handle the engineering, the Party Wall Act and Wandsworth Council building control as one coordinated job.
Structural work for Balham's period stock
Balham's terraces were built with rear closet wings and side returns, and over a century of settlement, damp and past alterations means no two need quite the same fix. We form new openings between the closet wing and the main house, replace tired or overloaded floor joists, and install supported openings where a wall is coming out but a beam must carry what sits above. Every element starts with an engineer's assessment.
Underpinning comes up here too, usually where a rear addition or a bay has moved, or where a basement is being deepened. We work to the engineer's design, excavate and pour in sequenced bays so the structure is never undermined, and keep Wandsworth Council building control involved at each stage so the completed work is properly certified.
Engineer and party wall across Balham
Because SW12 terraces are packed tightly against their neighbours, almost any structural alteration touches shared ground. New beams often bear into the party wall, and underpinning near the boundary is notifiable, so we serve the correct Party Wall Act notices before work begins rather than treating it as an afterthought. That keeps relations with the neighbour steady and your project on the right side of the law.
Steel beams are sized by the structural engineer, bear onto padstones and go in with temporary propping and staged demolition, never rushed. We book building control inspections at the points the inspector needs to see, from bearings to underpinning bays, and hand over the completion certificate at the end so your Balham home has a clean structural record.
