Some structural engineer briefs in Chelsea may raise neighbour interfaces under the Party Wall etc. Act 1996 — for example works to a shared wall, excavations near a boundary, or new structures astride a boundary. Not every structural engineer job is a party-wall matter.

If you already hold a party-wall notice, award or neighbour correspondence, attach it with photographs so professional input can be sequenced before irreversible build steps. This page does not invent a party-wall outcome from the SW3 postcode alone.
