Embedded in all our work, is the fundamental belief that architecture plays an invaluable role in shaping our cities. 41X Exhibition street is the epitome of this expression, designed as a hub for architecture and architects. Developed by the Australian Institute of Architects (AIA) to create new permanent space in the centre of Melbourne, the design was initially procured through a national design competition run by the Institute in 2008. The building hosts Institute members and the general public, and five of its floors are occupied by the Institute’s Melbourne offices, including the Victorian Chapter. The design is a hybrid entity, inviting public and commercial use while melding into the fabric of Melbourne cityscape. Met with the challenges of a confined site, the design demonstrates innovation and inclusivity, with a particular focus on dynamic sustainability solutions.
