Removing a wall to create an open-plan kitchen or a larger living room is one of the most popular alterations to London homes, and one of the most structurally sensitive. We provide the complete structural engineering service for load-bearing wall removal: confirming whether the wall carries load, designing the steel or timber beam that will replace it, producing calculations and drawings for building control, and checking the work on site. The result is an alteration that is safe, lawful and properly documented.
Many internal walls look identical whether they are structural or not, and guessing wrongly can lead to cracking, sagging floors or worse. A wall may support floor joists, a roof structure or another wall above, or provide lateral restraint to the building. Before any wall comes down you need a professional assessment and, if it is load-bearing, a properly designed beam with adequate bearings. Building control will expect structural calculations before approving the work, and buyers’ surveyors will look for that paperwork when you sell.
The process is straightforward:
We liaise with your builder throughout, so the design is practical to install as well as technically correct.
You receive a clear structural package: calculations demonstrating that the beam, bearings and padstones are adequate for the loads involved, a marked-up drawing showing the beam position, sizes and support details, and notes covering temporary propping and connection requirements. This package is prepared specifically for submission to your local authority or approved inspector, and it becomes part of your property’s records, giving future buyers and their surveyors evidence that the alteration was professionally designed and properly approved.
Fees depend on the complexity of the structure rather than the size of the opening alone. Key factors include whether the wall supports one floor or several, whether chimney breasts or existing beams complicate the load path, the age and condition of the building, whether more than one wall is involved, and whether you would like site inspections during the works. A simple single-beam design in a typical house involves far less work than a multi-storey alteration, and we confirm a fixed fee before starting.
Structural design is not a job for rules of thumb. Our RICS-qualified chartered surveyors and structural design team work to current British Standards and Eurocodes, carry professional indemnity insurance, and produce calculations in the format building control officers expect, which keeps approvals moving. If anything is ever questioned, whether by building control, a buyer’s solicitor or in a dispute, you have professionally prepared documents standing behind the alteration. That assurance costs little compared with the consequences of an undersized beam.
Much of our work is in the Victorian and Edwardian terraces around Notting Hill and west London, where original walls have often been altered several times before. Hidden flues, previous openings, shallow foundations and shared party structures all affect how loads travel through these buildings. We design with those realities in mind, and where a proposed opening affects a party wall or a neighbour’s structure, we can advise on your obligations under the Party Wall etc. Act 1996 at the same time.
