Structural Alterations in Mayfair.
Most of the houses in Mayfair were planned as a series of small rooms. Opening them up, whether that is knocking two reception rooms together, taking out the wall between the kitchen and dining room, or forming a wide opening onto the garden, is structural work, and it needs to be designed rather than improvised.
Our engineers design the steel beams, padstones and any temporary works, and our team installs them. The beam is usually hidden within the ceiling so the finished room shows no trace of the wall that was there. Building control inspects the work, and where the wall is shared with a neighbour we serve the party wall notices.
Structural alterations are often the first stage of a wider refurbishment, and we plan them as such, so the services, floor levels and finishes that follow are all designed together.

Mayfair: the houses and the planning rules.
Mayfair is Georgian London at its grandest: the Grosvenor Estate's squares and streets, five-storey townhouses on Mount Street and South Audley Street, mews behind, and later mansion blocks and apartment buildings. Most houses are Grade II listed, the whole district is a conservation area, and the Grosvenor Estate exercises its own control over many properties.
We have fitted kitchens on South Audley Street, working with ebony veneers, Corian and Miele appliances in rooms with original cornices and shutters. Projects here are logistically demanding: restricted parking, timed deliveries, concierge buildings and neighbours who expect a quiet, tidy site.
The Mayfair Conservation Area covers the whole district.
Westminster City Council
Planning and listed building consent are decided by Westminster, with Historic England consulted on the most significant houses.
Grosvenor Estate
Where the freehold is held by the Grosvenor Estate, its own consent and design guidance apply in addition to the council's.
Basements
Westminster's basement policy limits depth and extent under gardens and requires a Basement Impact Assessment.

Structural Alterations in Mayfair: your questions.
Can you remove a load-bearing wall in a Mayfair house?
Yes. Our structural engineer designs the steel beam and padstones, building control inspects the work, and if the wall is a party wall we serve the notices. The beam can usually be concealed within the ceiling depth.
Do structural alterations need planning permission?
Internal structural work does not need planning permission, but it always needs building regulations approval. Listed buildings need listed building consent for internal alterations.
