GA Zink and Sons Building

The tailoring business "G. A. Zink & Sons" was established in 1895 at 112 Oxford Street by German immigrant Gustav Adolph Zink, who in 1911 commissioned a four-storey premises at 56 Oxford Street, designed by architect John Dunstan and built by G. T. Brown around the first half of 1912 on a new block formed by the widening of Oxford Street and leased from the City of Sydney.^[2][3][4][5] Gustav Zink ran the business until his death on 28 August 1932, and is buried in Waverley Cemetery; he was succeeded in running the business by his son, Frank William Zink, who lived at "Devoncliffe" at 26 Lang Road, Centennial Park.^{[6][7][8][9][10]}

The business has continued at the 1912 location over several generations, experiencing booms in business in the interwar period and following World War II. The building was substantially renovated in the Inter-war period with a bold Art Deco style shopfront and entrance porch, designed by the shop-fitting firm of H. & E. Sidgreaves (who also made designs for the Paragon Cafe, Katoomba) and installed during the first half of 1938.^[11][12][13] Now known as "Zink & Sons", it continues to be operated as a family-run business, having been owned by the Jones Family since the late 1950s when Bill Jones took over the business from Thomas Zink.^[12][5]

A three-storey Federation Arts and Crafts style commercial building, with a symmetrical Inter War Functionalist shopfront with recessed central porch that has a polychrome terrazzo floor. The display windows on either side are surrounded by black Vitrolite relieved by two fine stainless steel strips. The name of the store is located in the hamper and consists of large individual stainless steel lettering in a stylised "modern" letter face. Other lettering includes the street number mounted at the top of the display windows.^[11] The ground floor and first floor interior contains a large amount of early fabric, much of it dating from the 1920s, including shelving, cabinetry, stairs and balustrades, etched glazing, partitions, and leadlight glazing.^[11]

No 56 Oxford Street is part of an architecturally consistent group of buildings that were the result of the resumption and widening of Oxford Street between Whitlam and Taylor Square.^[11] It is an exceptional and rare example of an Inter-War Functionalist style shopfront that is substantially intact, while the façade of the building at first and second floors incorporates finely detailed signage from the Federation era that is fully integrated with the fabric of the façade. The ground and first floor interior, despite modifications is a remarkably intact and rare example of a purpose-designed 1920s shop interior. It is the only building on the northern side of Oxford Street that was purpose-designed for a specific tenancy, G. A. Zink & Co, which has retained this original connection.^[11]
