GS Renovation creates open-plan and broken-plan spaces in Westminster's period homes, from kitchen-diners in Marylebone townhouses to knock-throughs in Pimlico and Belgravia. With over 30 years in W1, SW1 and W2, we combine grand period rooms into flowing, light-filled spaces while respecting the structure that holds these Georgian and Regency buildings up.
Open-plan conversions in Westminster townhouses
The classic Westminster knock-through joins two reception rooms, or a kitchen and dining room, into one generous space that suits how these homes are lived in today. In the terraces of Belgravia and Marylebone the dividing wall between those rooms is usually load-bearing, so we do not simply open it up. A structural engineer sizes a steel beam to span the opening, bearing onto padstones, and we prop the floors above while the wall is removed in stages.
Not every Westminster homeowner wants a single vast room, and broken-plan layouts suit these tall, formal interiors well. We keep a sense of separation with a wide supported opening, a part-height return, or slim Crittall-style glazed dividers that let light travel through while defining a snug or study. In leasehold mansion-block flats around Paddington and W9, many internal walls are non-structural partitions, which gives more freedom to reconfigure, though the freeholder's consent still applies.
Consents for open-plan living in Westminster
Opening up a Westminster home is internal work, so it is controlled under the Building Regulations rather than planning permission. Westminster City Council's building control inspects the beam, the padstones and the fire and ventilation arrangements before signing off. If your townhouse is listed, as many are in Mayfair and Belgravia, removing original walls or cornices may need listed-building consent, so we establish the property's status before any design is finalised.
Where the wall being opened is a party wall shared with a neighbouring house, the Party Wall Act applies and we serve notice before work begins, standard practice in the linked terraces of SW1 and W1. In a mansion-block flat we secure the freeholder's licence to alter, coordinate with the managing agent, and meet the building-management rules on sound insulation between flats. Whichever your home, we line up every consent up front.
