70 Castlereagh St, Sydney – A distinguished new identity

Located on a highly visible corner in the heart of Sydney’s luxury retail and legal precinct this project has cleverly repositioned an existing 14-storey commercial building. Bates Smart were initially commissioned by luxury retailer Chanel to prepare the design concept which was then approved and funded by the Owners Corporation.

Wrapping the building in a new glass facade addressed the existing facade leaks and poor thermal performance, while repositioned the building and reinforced the identity of its high profile retail tenants.


Design Director, Guy Lake, commented:

‘Working with Arup on the facade we developed an innovative methodology for over-cladding the existing façade which allowed tenants to remain within the building during construction. This eliminated the relocation and fitout replacement costs allowing the entire project budget to be allocated to a facade that reflected the buildings high calibre tenants.’

The new glass skin acts to unify the irregularity of the existing elevation’s disparate elements. It steps in and out to accommodate the existing structure while a series of frameless vertical glass fins provide a consistent alignment with the outer face of the building and create depth, shadow and texture across the façade.

The reuse of the structural elements of the existing façade system significantly reduced the materials required for construction and the amount of waste to be taken off site while the new glazing skin substantially improves thermal performance and reduces the building’s energy consumption.
