The project consisted of the complete demolition and refurbishment of the existing entry foyer in a live and operational Brisbane CBD building, with full public access maintained. The works included the demolition of an existing glass roof, structural demolition, a new glass façade and roof abutting into an existing heritage building, all new lobby finishes and fitout including a 10m high feature stone clad wall and a lift car upgrade.

The GPO is a place of local heritage significance included in the Heritage Overlay of Brisbane City Plan 2014, and also listed as a heritage place on the Commonwealth Heritage list. Delivered in three stages, the works acknowledge the significance of the site by delivering a high standard of materials and workmanship, and care and respect for the significant historical fabric.
