GS Renovation carries out structural alterations throughout Chislehurst, working on the Victorian and Edwardian terraces that fill the streets around Chislehurst Common and the BR7 postcode. Over more than 30 years in Bromley we have formed new openings, replaced tired joists, underpinned settled foundations and installed supported openings, all engineer-designed and building-control certified.
Common structural alterations in Chislehurst homes
The rear closet wings and side returns typical of Chislehurst's period stock often need structural attention. Homeowners come to us to widen an opening into the kitchen, cut a new doorway through a thick masonry wall, or replace floor joists that have sagged or suffered rot over a century of use. Each of these changes how load travels through the building, so every alteration begins with a structural engineer's assessment.
Where an opening is formed in a load-bearing wall, we install a steel beam or lintel sized to the span, bearing onto padstones so the load spreads into sound brickwork. For settlement, typically old shallow Victorian foundations or a movement crack near the bay, we underpin in controlled sections to deepen and stabilise the footing before making the wall good above.
Engineering and building control across BR7
Structural alterations in BR7 are notifiable under the Building Regulations, so Bromley Council's building control inspects the work at key stages, propping, steelwork, padstones and underpinning, and issues the completion certificate you will want when you come to sell. This is separate from planning, which only applies to exterior changes in a conservation area or on a listed building, not to internal structural work.
Because these terraces share a party wall with the neighbour, any alteration that cuts into or bears onto that shared wall, or any underpinning close to it, is notifiable under the Party Wall Act. You serve the notices, prop safely, carry out the work in staged sequence and coordinate the engineer's inspections, so the alteration is done once, correctly and with the paperwork in order.
