150 Grenfell Street

The 150 Grenfell project took two ageing office buildings and reimagined them into a single exemplar of sustainability and adaptive re-use. 

The existing services, fit-out and façade were removed and the structural framing modified to accommodate the new design. This included filling in previous lift shafts, creating a unified floor plate across the two buildings, adding a new sixth floor with a centralised plant level above and market leading innovations introduced.

Destined to be Adelaide’s first Carbon Neutral certified office in construction and operation, 6-star Greenstar, Platinum WELL and 5.5 star NABERS ratings are also targeted. Key upgrades include efficient glazing, a new lift lobby with oversized video screens and luxury end-of-trip facilities.

Built Environs’ involvement in the project was multifaceted, engaged under a Construct Only delivery model for the primary elements of the building, while simultaneously taking on a Design and Construct responsibility for the new curtain wall façade. This dual role underscores our holistic approach, integrating design and construction expertise for optimal results.
