Quay Quarter Tower is a skyscraper located at 50 Bridge Street, Sydney. Originally built as the AMP Centre in 1976, the structure underwent a redevelopment from 2018 which increased its height, incorporated additional floorspace, and modernised the tower's entire form and design. The building re-opened as the Quay Quarter Tower in early 2022 and currently stands at a height of 216 meters (709 feet) with 54 floors.^[1]^[2]^[3]

AMP Centre[]

The tower in its original form as the AMP Centre was built in 1976, consisting of 45 floors. It was used for commercial office space and was made up of concrete, glass, and steel. Designed by Peddle Thorp & Walker and built by Mainline. The center's roof-height reached 188m, making it the tallest building in Sydney at the time of its completion, prior to the completion of the MLC Centre in 1977.^[4]^[5]

Redevelopment (Quay Quarter Tower)[]

Proposals to redevelop the AMP Centre first surfaced in 2014. As a result of an international design competition, on 24 September 2014, the winning design from architect 3XN was revealed. Approval for the project was finalised in November 2015 and construction begain in early 2018.^[6]^[7] Construction was contracted by Multiplex and involved a rebuild and reclad of the building's entire exterior; increasing its height, incorporating additional floorspace, and modernising its overall design and facade.^[8] The AMP Centre's internal core, along with 66% of its existing columns, beams and slabs and 95% of its internal walls, were retained as part of the redevelopment.^[9] The northern half of the structure was dismantled and a more modern section was built in its place, incorporating it with the existing core and the southern section of the building, which was also reclad in a new facade.^[10] This redevlepment resulted in a new height of 216m with 54 floors. During construction, key-tenant AMP relocated its headquarters in March 2018 into the AMP Building at 33 Alfred Street, while all other commercial tenants found premises elsewhere in the city.^[11] The building in its new form, now known as Quay Quarter Tower, topped out in early 2021, before its completion in early 2022.^[12]^[13]
