GS Renovation installs RSJs and steel beams throughout New Malden, where the 1930s semi-detached and interwar houses of KT3 rely on internal load-bearing walls to carry the floors above. With over 30 years of structural experience across Kingston upon Thames, we open up these homes safely, from engineer's calculations to building control sign-off.
Removing load-bearing walls in New Malden semis
The wall between the front and rear reception rooms of a New Malden interwar semi is almost always load-bearing, carrying floor joists and often part of the chimney breast above. Before any steel goes in, we commission a structural engineer to size the RSJ, specify the padstones it bears onto and confirm the temporary propping needed while the wall comes down in safe, staged sections.
Because these houses were built in pairs on generous plots, the dividing wall with your neighbour is a shared party wall, so beam bearings and chimney breast work often trigger the Party Wall Act. We serve the correct notices, coordinate propping so the structure is never unsupported, and keep the KT3 home stable throughout the demolition and installation.
Padstones, propping and sign-off in KT3
Every steel we fit lands on a properly designed bearing. The engineer calculates the padstone size so the concentrated load from the RSJ spreads safely into the interwar brickwork, which on New Malden homes is usually solid or early cavity construction. We build in the padstones, seat and level the beam, then pack and pin the wall above so the floors settle back onto the new steel without cracking the plaster.
Kingston Council building control inspects the works at key stages, and we book those inspections so the beam is checked before it is boxed in. You receive the completion certificate that confirms the structural alteration meets the Building Regulations, which matters when you eventually sell your KT3 property and a buyer's solicitor asks for the paperwork.
