Canonical identity

This Public Seed preserves property-site and City-reported physical figures with their source semantics. Published contacts and service pathways are informational and do not authorize access, work, safety actions, or dispatch.

Property typeOffice
Management routeThe property tenant-resources page lists JLL-domain management contacts; scope and authority require confirmation before use.
Ownership claimThe property site and a December 2025 Cushman & Wakefield announcement identify Metropolis Investment Holdings as owner; legal title was not independently established.
LocationNot independently verified
02

Area claims stay separate

Gross, rentable, and office area are not interchangeable. Factum stores each measurement with its source meaning instead of choosing a convenient single number.
