This commercial office tower is located next to the heritage listed Ann Street Presbyterian Church, one of Queensland’s oldest churches. The project combines a heritage building with a contemporary office tower. Construction works for the project commenced in late 2009 with the refurbishment of the Presbyterian Church’s 3rd transept. The commercial office tower was completed in 2012.
Extensive works and re-planning within the existing 399 Bourke retail zone were required with the design team to ensure the structural integrity of the existing structure was maintained and the client’s expectations realised.
Key technical challenges
- Top down construction from ground level to basements by using plunge columns.
