A traditional solution

29 Marlborough St, Malvern SA

The clients requested a traditional solution to the sustainable brief which is expressed in the form of the building. The brief called for extensive accommodation to be dispersed over a relatively small block of land. The brief was met by distributing some of the spaces on a second level, largely within the roof space. This enabled the single storey scale to be maintained in the streetscape.

The upper level has been prepared for air conditioning to the first fix stage, but will only be commissioned once the performance has been determined over a year’s cycle.

Whilst some design strategies have been lost due to the traditional form of the building, it demonstrated excellent climatic response as soon as lock was achieved.
