Precision scope: Contributor-mapped polygon for the exact named London 4 building, used only to locate the selected facility-build project. It is not an official building footprint, parcel, complete present or future campus boundary, five-building plan, security boundary, or current construction-progress extent.
Horizontal uncertainty: Not reported
OpenStreetMap supplies no survey, cadastral, planning-boundary, or numeric horizontal-accuracy statement.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
