GS Renovation installs RSJs and structural steel beams across Southall, where the housing is largely 1930s semi-detached and interwar suburban homes on generous plots in the UB1 postcode. With over 30 years of building and structural experience in West London, we remove load-bearing walls safely and open up these solid, well-built interwar houses.
Steel beam design for Southall interwar semis
The 1930s semis around Southall and neighbouring Hanwell were built with substantial masonry, and the wall between the front and rear reception rooms is almost always load-bearing. Before any steel goes in, a structural engineer calculates the beam size for the span and the loads above, then specifies padstones to spread the bearing onto sound masonry at each end. Nothing is guessed, and every RSJ is sized to the actual weights it will carry in that particular house.
On site we set out temporary propping to support the floors and roof above, then carry out staged demolition so the structure is never left unsupported. The RSJ is lifted into position, seated onto its padstones and packed tight, and only then is the propping struck. It is careful, methodical work that suits the solid construction of these interwar Southall homes, and building control inspects and signs off every beam.
Party wall notices on shared Southall walls
Many Southall semis share a party wall with the neighbouring house, and the chimney stacks and dividing walls often sit within it. When a beam bears near or into that shared wall, the Party Wall etc. Act applies, so notice must be served on the adjoining owner before work begins. We help homeowners understand when notices are needed, and we coordinate the process so the structural work stays lawful and the relationship with the neighbour stays sound.
Getting the party wall side right matters in a street of attached UB1 semis, where the same solid brickwork runs between two households. We plan the propping, the bearing points and the sequence so vibration and disruption to the adjoining property are kept to a minimum. Building control notification runs alongside, so the finished opening is inspected, recorded and signed off, giving you a clean paper trail for the future sale of the home.
