Can I remove a load bearing wall
You can often remove a load bearing wall, but the loads it carries must be transferred safely. For a typical structural alteration, building regulations approval is needed. The replacement may involve a beam, posts, supporting masonry and suitable foundations.
How do you know whether a wall is load bearing
Wall thickness and the sound made when tapping it are not reliable tests. A wall may support floors, roof members or another wall, and an apparently lightweight partition may have a structural role.
Ask a competent designer to inspect the arrangement. Opening up may be necessary where finishes hide the structure or earlier alterations are poorly documented.
Is a beam calculation enough
A calculation should sit alongside drawings showing how the beam is installed and supported. The design needs to explain bearings, connections and the capacity of the structure below. Part A is concerned with the complete load path.
Temporary support is a separate practical issue. The contractor needs a safe sequence for supporting the building while the wall is removed. Discuss that sequence before work starts.
What other regulations might apply
Opening a kitchen into a hallway may change a fire escape route. Exposed steel may need fire protection. Changes to services, ventilation and sound separation can also need attention.
For example, creating an open plan ground floor in a house with a loft bedroom should prompt a fire safety review as well as structural design.
What should you keep afterwards
Keep the approved drawings, calculations, inspection correspondence and completion certificate. Record any agreed design changes. Photographs taken before the beam is covered can help explain the installation, although photographs do not replace inspection.
If the work involves a party wall, assess the separate notice requirements before starting.
