GS Renovation carries out structural alterations throughout Surbiton, from new openings and replacement joists to supported openings and underpinning in the bay-fronted Victorian and Edwardian terraces of KT6. With over 30 years of building experience near Richmond Park and the Thames, we handle the engineering, the neighbours and Kingston building control on one job.
Structural alterations for Surbiton period homes
The rear closet wings and side returns typical of Surbiton's terraces are often where owners want change, whether that is a wider opening into a rear extension, a new door punched through a solid wall or joists replaced where a century of use has left them springy. Each of these is a structural alteration, and each begins with an engineer specifying the beam, lintel or timber sizes for the loads involved.
New openings need a steel or concrete lintel, or an RSJ where the span is wide, bearing onto padstones at each side. Replacement joists must match the depth and spacing the floor requires. Where old foundations have moved, underpinning deepens them in short sequenced sections so the wall is never undermined. We prop, work in stages and never rush a load off its support.
Consents and sign-off around Surbiton
Almost every structural alteration in a Surbiton terrace touches the party wall shared with the neighbour, whether it is a beam bearing, a new opening near the boundary or excavation for underpinning. All of these are notifiable under the Party Wall Act, so we serve the correct notice on the adjoining owner and, for excavation work, provide the details they are entitled to see before we dig.
This is Building Regulations work, overseen by Kingston Council's building control rather than the planning department, so no planning permission is needed for internal structural changes. Planning only comes into play for exterior alterations in a conservation area or to a listed building. We book the building control inspections at the right stages and keep the engineer's calculations on site for the inspector.
