GS Renovation carries out structural alterations throughout Deptford, from new openings in Georgian spine walls to replacement joists and underpinning in the older SE8 stock. With more than 30 years of building experience across the Lewisham area, we plan every alteration around an engineer's design and get it signed off correctly.
Structural alterations for Deptford period homes
The Georgian and Regency townhouses around Deptford present a full range of structural work: forming supported openings between reception rooms, replacing tired or overloaded joists, and creating new doorways through solid brick. Many of these SE8 properties are listed or in a conservation area, so we begin with a structural engineer's assessment and, where the exterior is touched, check what consent Lewisham Council requires.
New openings are formed with a correctly sized beam bearing onto padstones, propped temporarily while the masonry above is removed in stages. Where original joists have sagged or been notched over the decades, we design replacements to modern spans. Underpinning, where settlement or a basement dig demands it, is carried out in engineered bays to keep the building stable throughout.
Engineered design and building control in SE8
Every structural alteration we make in Deptford starts with calculations. The engineer specifies the steel sections, padstone sizes and any underpinning sequence, and that design becomes the basis for the works. This matters in tall, closely built SE8 terraces where a change on one floor affects the loads carried right down to the foundations.
Structural alterations are notifiable under the Building Regulations, so Lewisham building control inspects the propping, the bearings and the finished work before sign-off. Where an opening, beam or underpinning affects the shared party wall with the adjoining Deptford house, the Party Wall Act applies and notice is served on the neighbour. We manage the engineer, the notices and every inspection.
