About 41X

The 41X project was developed by the Australian Institute of Architects to create new space for its long-term use in the center of Melbourne. The building accommodates a dense program on a small site area, with rental offices above the headquarters and public display area for the AIA. The small floor plate enables small businesses to create their own identity within the building. As opposed to the common trend of moving to low-rise, large floor-plate buildings, this development offers boutique-sized floor plates of 280 square meters each, on a site area of 330 square meters.

As a typical tower/podium setback arrangement was impossible, the design “chisels” the lower levels to create intimate public spaces and conceptually draw the city street up into the building through a feature stair at the perimeter. The building’s “Sustainability Charter” will be incorporated in to the owner’s corporation rules and mandates the use of 100 percent green power and minimum commitments to carbon offsetting through the Australian Carbon Trust.
