GS Renovation installs steel beams and RSJs across Wandsworth, from the red-brick mansion blocks near Battersea Park to the purpose-built period flats around Balham and Tooting. With over 30 years of structural work in SW8, SW11, SW12, SW15, SW17 and SW18, we open up load-bearing walls safely and sign every job off with building control.
Steel beam work in Wandsworth mansion flats
Removing a load-bearing wall inside a Wandsworth mansion flat is rarely a simple job. Many of these red-brick blocks in SW11 and SW18 hold their loads through internal masonry, so a structural engineer must size the RSJ and specify padstones before any demolition begins. We install temporary propping, take the wall down in safe staged sections and seat the new beam onto its bearings so the flat above stays fully supported throughout.
Leasehold reality shapes every step. Most flats in these blocks need the freeholder's licence to alter, and the managing agent will want the engineer's calculations and our method statement before work starts. We coordinate that paperwork, keep to the building-management rules on working hours and access, and protect communal stairwells and lifts. Building control inspects and signs off the completed steelwork so your alteration is properly certified.
Load-bearing walls in Wandsworth period homes
Where we work on period flats and houses across SW12 and SW17, the wall between two rooms is often part of a shared party wall or carries the floor above. Under the Party Wall etc. Act 1996, cutting into a wall shared with a neighbour usually means serving notice, so we help you appoint a surveyor and time the works around the agreed schedule. The engineer confirms the beam size and the bearing detail before anything is disturbed.
On site we prop first, then demolish in controlled stages, keeping dust down in an occupied home. The RSJ lands on padstones spread to carry the point loads into sound masonry, and we pack and pin above the beam so there is no settlement. Nothing is closed up until building control has inspected the steel, the connections and the fire protection, giving you a completion certificate for your records.
