GS Renovation creates open-plan living in Mayfair's grand period residences, from knock-throughs between reception rooms to kitchen-diners and broken-plan layouts framed by Crittall dividers. With 30+ years in W1, near Hyde Park, Oxford Street and the West End, we open these Georgian and Regency townhouses up while respecting every ounce of their period character.
Open-plan layouts in Mayfair townhouses
Mayfair's Georgian and Regency townhouses were planned as a series of formal rooms, so opening them into a flowing kitchen-diner or a broken-plan living space almost always means removing loadbearing masonry rather than a light partition. On these tall W1 plots the walls carry real load, so a structural engineer sizes the beam and specifies the bearings before any wall comes down.
We install steel beams on padstones, prop and demolish in safe stages, then transfer the load once the steel is set. Where you want zones kept without losing light, Crittall-style glazed dividers let the space read as one while defining a diner or study. Original cornicing, shutters and joinery are protected and reinstated so the openness feels of the house, not imposed on it.
Getting an open plan signed off in W1
The steelwork behind an open-plan conversion is controlled under the Building Regulations, and Westminster City Council's building control inspects the propping, beams and padstone bearings before completion. We plan the works around your household so a lived-in Mayfair home stays as calm and usable as possible while the layout changes.
Because the new beam usually bears into the party wall shared with the neighbour, the Party Wall Act applies and we serve notice before work begins. And as so many Mayfair townhouses are listed or sit within a conservation area, altering internal fabric can require listed-building consent; we establish the property's status early and arrange every approval so your open plan is fully compliant.
