From new openings and replacement joists to supported openings and underpinning, GS Renovation carries out structural alterations across Barnes and SW13. Working on the area's bay-fronted Victorian and Edwardian terraces for over 30 years, we understand how these period homes are put together and design alterations that respect the original structure while opening it up for modern living.
Structural alterations for Barnes period homes
Barnes terraces were built with load-bearing masonry walls, timber floor joists and rear closet wings, and each of those elements has to be respected when you alter them. Forming a new opening in a spine wall, replacing joists that have sagged or spanning a wide steel all begin with a structural engineer's calculations, so the new arrangement carries the loads exactly as the original did.
Underpinning is sometimes needed where an SW13 property near the Thames has settled or where you are lowering a floor to gain head height. We excavate and pour in controlled sections beneath the existing footings, working to the engineer's sequence so the house stays supported throughout. Whatever the alteration, every steel bears onto padstones and every change is designed before a single brick is disturbed.
Party wall and consent in Barnes
Most structural alterations in Barnes touch the party wall shared with the house next door, whether you are cutting a new opening, bearing a beam into it or underpinning alongside it. That makes the work notifiable under the Party Wall Act, so you serve notice on the neighbour and agree the details before starting. Getting this right early avoids disputes and keeps a tightly built terrace's neighbours onside.
The structural work itself is signed off by Richmond Council under the Building Regulations, not by the planning department. We arrange building control, book the inspections at the key stages and provide the completion certificate at the end. Only exterior changes in one of Barnes's conservation areas need planning consent, so an internal alteration stays a building control matter that we manage from start to finish.
