GS Renovation installs RSJs and structural steel beams throughout Mayfair, from the Georgian townhouses off Grosvenor Square to the Regency homes near Hyde Park. With over 30 years of structural work across W1, we remove load-bearing walls safely, working carefully within Westminster City Council's conservation and listed building framework.
Steel beam installation in Mayfair townhouses
The Georgian and Regency townhouses of Mayfair are built with solid brick walls and deep internal partitions, many of them load-bearing across several storeys. Removing one to open up a reception floor calls for a steel beam sized by a structural engineer, bearing onto padstones at each end. We install temporary propping first, then take the wall down in careful stages so the floors above stay fully supported throughout the works.
Because so many W1 properties are listed or sit within a conservation area, we approach every job with Westminster City Council's controls in mind. Internal structural work needs building regulations approval and building control sign-off rather than planning permission, though listed status can add a requirement for listed building consent. Where the wall is shared with the neighbouring townhouse, the Party Wall Act applies and we serve the correct notices before starting on site.
Load-bearing wall removal in Mayfair
Opening a Mayfair home for a larger kitchen or a through reception usually means taking out a spine wall that carries the joists above. Our team props the structure, forms new padstone bearings and lifts the beam into place, then rebuilds around it so the finished opening looks original to the period. Every stage follows the engineer's drawings and is inspected by building control before we plaster and make good.
Steel work in these tall, narrow townhouses often means moving beams up several flights or through restricted rear access shared with Belgravia and Marylebone streets. We plan the lifting, protect original cornicing, staircases and joinery, and keep a clean, dust-controlled site because most of our Mayfair clients remain in occupation during the build. On completion you receive the engineer's calculations and the building control certificate for your records.
