GS Renovation installs RSJs and steel beams across Westminster, from the grand stucco terraces of Belgravia to the period mansion blocks of Marylebone and Pimlico. With over 30 years of structural work in W1, W2, SW1, WC2, NW8 and W9, we open up Georgian and Regency townhouses safely, working within the borough's many conservation areas and listed constraints.
Steel beams in Westminster period townhouses
Removing a load-bearing wall in a Georgian or Regency townhouse in Mayfair or Marylebone is precise work. We start with a structural engineer sizing the RSJ to the loads above, then set out temporary propping before any staged demolition begins. The beam bears onto engineered padstones cut into the solid masonry, spreading the load into walls that have carried these tall Westminster elevations for two hundred years.
Many of these townhouses are listed or sit within a conservation area, so internal structural change is handled with care and, where the fabric is protected, checked against listed building consent. We keep dust down, protect original cornicing and joinery, and coordinate every stage so an occupied home in SW1 or W1 stays liveable while the steelwork goes in.
Party wall notices across Westminster terraces
Westminster's terraces and mansion blocks share party walls, so a chimney stack or dividing wall you want to remove is very often a shared structure. Under the Party Wall Act, that means serving notice on the neighbouring owner before work starts. We flag this early on projects in Pimlico, Paddington and Belgravia, so beam installation is never held up by paperwork raised at the last minute.
For mansion flats in NW8 or W9, the reality is leasehold. Structural change usually needs the freeholder's licence to alter and coordination with the managing agent, alongside building control sign-off for the beam itself. We manage the engineer's calculations, the building regulations application and the inspections, giving you one accountable team from first prop to final certificate.
