GS Renovation carries out structural alterations across Charlton's Victorian and Edwardian terraces, from new door openings in the spine wall to replacement joists and underpinning. With 30+ years working in SE7 near Greenwich Park, Blackheath and the O2, we design, prop and build supported openings that building control signs off with confidence.
Structural alterations across Charlton homes
Charlton's bay-fronted terraces come with familiar structural quirks: rear closet wings tacked onto the back, side returns crying out to be filled in, and original joists that have sagged or been notched over the decades. Whether you want a new supported opening between kitchen and dining room or a wider run of steel to carry a rear extension, we start with a structural engineer's design tailored to what your house is actually built from.
For supported openings we size and install steel beams on padstones, prop the loads temporarily, then rebuild the masonry above once the steel is bearing. Where floors have failed we fit replacement joists to the correct span and grade, and where foundations have moved on Charlton's clay we underpin in sequenced bays so the ground is never left unsupported beneath your walls.
Engineering and sign-off in SE7
Any alteration that touches a wall shared with the neighbour, or a party wall the beam bears into, is notifiable under the Party Wall Act. In SE7's tight terraced streets that is common, so we serve the correct notices early and record the condition of the adjoining property before we lift a tool. It keeps relations with neighbours calm and your position protected.
Structural alterations are governed by the Building Regulations, so the Royal Borough of Greenwich building control inspects the works and issues the completion certificate. Only exterior changes in a conservation area or to a listed building would need planning consent as well. We coordinate the engineer, the notices and every inspection so the paperwork matches the steel that is actually in your house.
