Architecture news & editorial desk How do you transform two heritage buildings created for another era (and purpose) into a modern sustainable development offering A-Grade offices, boutique retail and event spaces? SubStation No. 164 at 183-185 Clarence Street in the heart of Sydney CBD is a standing example of what can be achieved when conventional thinking about heritage buildings is challenged. The two historic Sydney buildings – a former 1909 spirit warehouse and the adjoining 1930s electrical substation – lay dormant and unused for decades until they were taken up for restoration and refurbishment. Based on the winning design by fjmt architects design director Richard Francis-Jones, the two buildings have been transformed by Built into one of Sydney’s most exciting office developments that not only pushes the boundaries of heritage redevelopment but also has become the benchmark for heritage restoration in Sydney.
