GS Renovation removes load-bearing walls in Mayfair's grand period residences, from the Georgian townhouses off Hyde Park to the Regency homes near Oxford Street and the West End. With over 30 years of structural work in W1, we open up these prestige homes safely, insert engineered steelwork and leave a finish worthy of the address.
Taking out a structural wall in Mayfair
Mayfair's Georgian and Regency townhouses were built with solid loadbearing masonry, so the wall you want gone is often carrying the floors and the storeys above rather than a simple partition. On these tall, narrow W1 plots the loads run high, which is exactly why we open every job with a structural engineer who calculates what the wall holds and sizes the steel beam or RSJ to suit.
The engineered beam bears onto padstones cut into sound masonry at each end, spreading the load into walls that can take it. We prop the structure temporarily, take the wall down in controlled stages, lift the steel into position and only then transfer the load. In a listed or conservation-area home we work cleanly around original cornicing, panelling and joinery so the period character survives the opening.
Party wall and building control in W1
Because Mayfair terraces share a party wall with the house next door, cutting a beam pocket or bearing into that shared wall is notifiable under the Party Wall Act, and you serve the correct notices on the neighbour before a tool is lifted. On these prestige streets, discreet, well-documented notice-serving keeps relations with adjoining owners calm from the outset.
The structural design and steelwork are signed off under the Building Regulations, with Westminster City Council's building control inspecting the propping, the beam and the padstone bearings. Where the townhouse is listed, listed-building consent can also be required for alterations affecting its special character, and we help you establish and satisfy that before work begins so nothing is left uncertain.
Contracts, insurance and your duties as client
Structural work on a Mayfair house deserves paperwork that matches its value. Before we start you should have a written contract setting out the scope, the programme, the payment stages and how variations are handled, along with evidence of our public liability and contractors' all risks cover. It is also worth telling your own insurer that structural work is planned, because many household policies expect notice and some conditions change while a property is opened up.
There are duties on your side too, though they are lighter than people fear. Under the construction regulations a domestic client's duties normally pass to the contractor, so we take on the planning and management of health and safety. What you retain is the responsibility to give us the information you hold about the building, such as asbestos surveys, previous structural reports and any as-built drawings. We ask for those at the outset rather than discovering them halfway through.
