The source relation 21219171 and outer way 150608764 cover the connected heritage complex, including adjoining buildings beyond WSSH. The source label is historic (Information Technology Services), and is retained in metadata rather than presented as current occupancy. OSM inner way 1549071536 retains the courtyard void.

WSSH identity, component arrangement and roof character are cross-referenced to the official PPSSCC-141 planning application / DA443/2020, approved 3 March 2021. Drawings: SH.AR.DA.0001, AR.S60.1001, AR.S60.2006 and AR.S60.4003. https://www.planningportal.nsw.gov.au/planning-panel/alterations-and-additions-0

The 3D view has two distinct layers: unmodified geographic footprint context, and an interpreted architectural model of the C107/C104/C104a portions. Component partition lines and rectangular roof masses are simplified. Height, roof pitch, chimney dimensions and window spacing are visual estimates based on elevation proportions, NOT measured, certified or as-built dimensions. The UI labels this limitation. Unknown surrounding building heights stay flat. Room locations, interior furniture, live occupancy and current access routes are not modelled. The interactive digital tour is a thematic guide, not indoor navigation. Plans are linked at source; no third-party architectural drawing or photograph is redistributed.
