Rules and safety
Taking out or altering a load-bearing wall needs a structural engineer's design and building control approval. Work on a wall shared with a neighbour may need a party wall notice. Building work is covered by the Construction (Design and Management) Regulations 2015, which set duties for clients, designers and contractors. Check the asbestos survey before cutting into old walls, floors or ceilings.

Questions
General building work: common questions
Do I need an engineer?
For anything structural, such as removing a wall or adding a steel beam, yes. Your builder can usually arrange one.
Do I need building control approval?
Structural alterations normally do. The builder or engineer can submit the application.
Can the work be done while we are open?
Often, with dust screens and noisy work planned out of hours.
