A development application for a 13-storey mixed-use building designed by Tzannes has been lodged with the City of Sydney.
The site, owned by NGI Investments, is located at the intersection of Martin Place and Wynyard Park at 4-6 York Street in Sydney’s CBD. It is currently the only undeveloped site on York Street. Construction and excavation works would involve the demolition of existing structures on the site.
The proposed development would also include alterations and additions to the adjacent to the former Bank of New South Wales building at 341 George Street, which was designed and constructed between 1927 and 1932.
Tzannes said in its design report that the historic George Street building – an inter-war Palazzo style – forms a “prominent part” of the western bookend of Martin Place and the heritage fabric of the street, consisting of original bank chambers on the ground floor, a mezzanine level and commercial floors above. It also includes two basement levels, one of which includes the building’s original safe deposit area.

The proposed York Street development will incorporate a granite masonry facade that references the lower section of the bank building. The middle section of the bounding would be clad in a high performance curtain wall with spandrel zones aligned with 341 George Street’s sandstone masonry cladding.
The rooftop would consist of a green roof and photovoltaic cell arrays, reducing the heat retention of the rooftop, minimizing and offsetting embodied carbon, and improving the building’s overall performance.
Tzannes said the project would improve the connectivity of York Street, providing tapering setbacks at ground level to create comfortable and sheltered public walkways.
The building is designed to achieve the City of Sydney’s minimum requirements and will target a 6-Star NABERS Energy rating, a 4-Star NABERS Water rating, and a 5-Star Greenstar rating.
Plans for 4-6 York Street are on exhibition until 20 January 2023. The project is estimated to cost around $36 million.
