GS Renovation installs RSJs and steel beams across Harrow, from the 1930s semi-detached houses of Pinner to the interwar homes around Stanmore Common. With over 30 years of structural experience across HA1, HA2, HA3, HA5 and HA7, we remove load-bearing walls safely and open up these generous suburban interiors.
Removing load-bearing walls in Harrow semis
The interwar semis that fill Harrow were built with a load-bearing spine wall between the two front and rear reception rooms, and homeowners in HA5 and HA7 regularly ask us to take it out. Every job starts with a structural engineer sizing the beam for the actual span and load above, so the steel is specified correctly rather than guessed, and Harrow Council building control signs off the calculations before we begin.
On site we install temporary propping to carry the floors and roof above, then carry out staged demolition so nothing is removed until the load is safely supported. The new RSJ bears onto concrete padstones at each end, spreading the weight into the existing masonry. Only once the steel is seated and the propping struck do we make good the openings, ready for plastering.
Party wall steelwork on shared Harrow walls
Because Harrow's houses are predominantly semi-detached, the wall between you and your neighbour is a shared party wall, and any chimney breast or beam bearing that touches it falls under the Party Wall Act. We flag this early, help you serve the correct notices on the adjoining owner, and schedule the steelwork so relations with the neighbour stay straightforward from HA1 through to Stanmore.
Where a beam needs to bear into a party wall, the padstone and bearing detail are designed so the load transfers without disturbing the neighbouring property. We coordinate the engineer's design, the building control inspections and the party wall timeline together, keeping the structural work on programme. It is exactly the kind of accountable steelwork that thirty years across North West London has taught us to manage cleanly.
