Notices
When one project needs more than one notice
A rear extension on a terrace can need a party structure notice and an adjacent excavation notice. They are not interchangeable.
This is general information for England and Wales. It is not a decision on your building. Status: pending project-specific review by a qualified Party Wall professional. House-style review 27 September 2026.
Do not collapse them into one vague letter
Each notice has its own job. Mixing them into a homemade note, or a text message, is a common reason a file has to be served again.
Two neighbours means two recipient lists. A flat above either house can add a freeholder or a leaseholder. The fee for notice work is described per adjoining owner for that reason.
If the design is still moving
Serve against the revision you will actually build. If the steel or the foundation depth changes afterwards, tell the case desk before the neighbour is told the old drawing still stands.
A Party Wall Notice does not replace planning permission, building regulations approval, leaseholder or freeholder consent, or structural advice. This platform does not provide legal advice and does not issue Awards.
