Atop its Modernist base this new garden room for a private women’s club borrows the established landscape across the lane and adds a further tectonic layer to the original building by Ellison Harvie. Celebrating its arboreal aspect from the neighbouring trees, the addition which accommodates a major function space, was conceived of as a conservatory. The design approach interweaves and overlaps new and old. The rhythm of the roof and other new elements – both structural and not – take their cue from the original one set by Harvie in the distinctive mullion window wall that encompasses level 1 and 2. While both architectures draw from a Modernist repertoire their alternate interior atmospheres and laneway presentation complement each other through subtle difference.
