89 York St, Rooftop Additions


A project to add multiple additional floors to an existing 11-storey office tower in the Sydney CBD. Awarded through a short, design-excellence process with the City of Sydney, we proposed that the addition should respond to its significant heritage neighbours while continuing the geometric system of the otherwise non-descript 70’s office block it was to crown. We proposed a facade that responded to the deep, punctured masonry openings of surrounding heritage brick warehouses and office buildings that employed a ‘wedding-cake’ form to step back from the street and minimise the impact of the increased street-wall height on the streetscape.
