Structural Alterations Bexley

GS Renovation carries out structural alterations throughout Bexley, working on the 1930s semi-detached and interwar houses that fill Bexleyheath, Sidcup and Welling. Over 30-plus years across DA5, DA15 and SE2 we have formed new openings, replaced tired joists, underpinned settled foundations and installed supported openings, each one designed by a structural engineer and signed off by building control.

Structural work on Bexley's interwar houses

Interwar suburban houses in Bexley were built to the standards of their day, and after ninety years some need more than cosmetic work. We form new openings for wider doorways and rear extensions, replace joists softened by old leaks near bay windows, and create supported openings where a steel beam and posts must carry a wall that is being partly removed rather than taken out entirely.

Underpinning is occasionally needed where the generous clay-rich plots common in DA5 and DA15 have caused seasonal foundation movement. Whatever the alteration, a structural engineer produces the design and calculations first, we prop and work in controlled stages, and every steel bears onto properly sized padstones so the loads are carried safely down through the structure.

Engineer and building control across DA15

Every structural alteration in Bexley is notifiable under the Building Regulations, so Bexley Council's building control inspects the work and issues the completion certificate. This is separate from planning: only exterior changes to a listed building or a conservation-area property need planning consent, and internal structural work does not.

Because Bexley's semis share a party wall with the house next door, alterations that cut into or load that wall are notifiable under the Party Wall Act, and you serve the correct notices in good time. We coordinate the engineer, the party wall paperwork, the propping and steelwork, and the building control inspections as one package, so nothing falls between trades.

• Steel goalpost and portal frames to the engineer's design
• Drainage diversion and build-over agreements where required
• Party Wall Act 1996 notices, awards and schedules of condition
• Lintel replacement and repair over failed openings
• Bressummer and bay window support to period frontages
