GS Renovation carries out structural alterations throughout Bromley, from new openings in interwar semis around Orpington to replacement joists and supported openings in the period houses near Beckenham Place Park. With 30+ years across BR1, BR2, BR5 and BR6, we design, prop, build and certify structural changes to these generous suburban homes.
New openings and supported spans in Bromley
Structural alterations cover more than one job. Across Bromley we form new openings between rooms, insert replacement joists where floors have sagged in older interwar houses, create supported openings for wide doorways and, where foundations are inadequate, carry out underpinning. Each of these changes the way loads travel through the house, so every one begins with a structural engineer working out the forces before any tool touches the wall.
For a new opening the engineer sizes a steel beam or lintel and specifies padstones to carry it into sound masonry. On the generous plots common in BR6 and BR7, rear openings onto the garden are popular, and these need proper cavity closing and thermal detailing as well as structural support. We prop first, cut and build in the correct sequence, then make everything good.
Underpinning and building control in Bromley
Some Bromley homes, particularly older period properties on clay-influenced ground towards Chislehurst, show movement that calls for underpinning. This is deliberate, engineered work: excavating and pouring in short bays to a designed sequence so the existing structure stays stable throughout. It is not a job for guesswork, and it is always designed by an engineer and inspected as it proceeds.
All of this structural work is controlled under the Building Regulations, and Bromley Council's building control inspects the key stages and issues the completion certificate you will need when you sell. Where a beam bears into, or an alteration affects, the party wall shared with an adjoining semi, we serve Party Wall Act notice on the neighbour first. We coordinate engineer, notices and inspections as a single process.
