GS Renovation installs steel beams and RSJs across Stanmore, working on the substantial 1930s semi-detached and interwar houses that fill the HA7 postcode. With over 30 years of structural experience in North West London, we open up load-bearing walls safely, from homes near Stanmore Common to the wider streets around Harrow.
Steel beam sizing for Stanmore interwar homes
The interwar houses across Stanmore were built with load-bearing internal walls that carry the floors above and, in many cases, a chimney breast and stack. Before any wall comes down, we arrange a structural engineer to calculate the loads and specify the correct RSJ or steel beam. That beam then bears onto padstones at each end, spreading the weight into the masonry so the structure above stays fully supported once the wall is gone.
On generous HA7 plots the ground floors are often wide, which can mean a longer span and a heavier beam than a typical terrace would need. We plan the bearings, the padstone size and the propping to suit each home rather than working to a standard detail. Everything is checked and signed off by Harrow Council building control, so you hold a clear record that the structural work meets building regulations.
Safe propping and party walls in Stanmore
Removing a load-bearing wall is a staged job. We install temporary props and needle beams to take the load, then carry out controlled demolition in sequence rather than all at once. Only when the steel is seated on its padstones and fully bearing do we strike the props. In an occupied Stanmore home we protect floors and furniture, manage dust and keep the working area contained so daily life carries on around us.
Many Stanmore semis share a party wall with the neighbouring house, and the dividing wall or chimney breast frequently sits within it. Where your steelwork affects that shared structure, the Party Wall Act applies and notice must be served on the adjoining owner before work starts. We flag this early, explain the timescales and coordinate the notices so the project runs to plan without any dispute with next door.
