Hill House / Andrew Maynard Architects

Andrew Maynard Architects, Melbourne, Australia:

Rather than repeating past mistakes and extending from the rear in a new configuration, the proposal was to build a new structure on the rear boundary, the southern edge of the block, upon the footprint of what had been, until now, the back yard. The new structure faces the sun, the pure cantilevered box above acts as the passive solar eave, cutting out summer sun, while letting winter sun flood in.

Following the decision to build at the rear of the block a ubiquitous modern box was first imagined. Soon it seemed necessary to pursue the opportunity to activate this new, once shaded, now sunny facade. A seat along the new northern facade? Perhaps a series of steps like the Scalinata della Trinità dei Monti? But how does one lounge in the sun on steps. Perhaps a slope instead …. And the hill house evolved/emerged.

The new structure faces the original house. The backyard is now the centre of the house activated by the built form around it. Beyond solar gain, the benefit of the new structure being in the backyard is that it borrows landscaping from its neighbours’ gardens. The high windows about the entertainment cabinetry and the dining area are enveloped in trees. Internally one gets the sense that Hill House is enveloped by bush rather than part of the suburban mix.
