From new openings to replacement joists and underpinning, GS Renovation carries out structural alterations throughout Brixton's Victorian and Edwardian terraces. With over 30 years working across SW2 and the wider Lambeth stock, We build supported openings to the engineer's design that let these period homes work for modern living while staying structurally sound.
Structural alterations across Brixton's period stock
Brixton's terraces come with quirks that shape every alteration: rear closet wings, side returns and original softwood joists that can sag or have been notched over the decades. Whether you want a wider opening between two reception rooms, a supported opening into a side-return extension or replacement joists across a tired floor, we start with a structural engineer assessing what is there and what the change demands.
Every supported opening is formed with a steel beam sized to its loads, bearing onto padstones, with the masonry above needled and propped while the steel is set. Underpinning to stabilise settled foundations, common where these SW2 homes sit on London clay, is designed by the engineer and dug in short, sequenced bays so the terrace stays supported throughout.
Engineering and consents in SW2
Because Brixton's terraces share party walls with the houses either side, many alterations, new beam bearings, chimney work or underpinning near the boundary, are notifiable under the Party Wall Act, so you serve notice on the affected neighbours before we start. We coordinate the surveys and schedules of condition so the paperwork is settled well ahead of the build.
Structural alterations fall under the Building Regulations, so Lambeth Council's building control, or an approved inspector, reviews the engineer's calculations and inspects the work at key stages. We manage that from first drawing to final certificate, so your beams, joists or underpinning are formally signed off and documented for when you come to sell.
