Source project V8-ARK-HILFIELD: Ark Hilfield Park / former Mercure Hotel. The retained developer location URL is https://www.ark-d-c.com/locations/elstree and the project identity refers to Hertsmere planning application 25/1781/FUL; use Elstree locality only, not either grid-supply substation. Locality representative point only; no site coordinate inferred.
Map points are not surveyed parcel boundaries or electricity connection nodes. The stage is a source-based interpretation at the evidence cutoff, not a current-status check.
