Upper House is a 17 storey building consisting of 110 apartments and two street level commercial tenancies. The building employs community spaces and amenity orientated design principles, acknowledging sustainability that is both social and environmental. The unique building composition was conceived through a series of urban design gestures. The central mass is fragmented by a ‘ravine’ that articulates two separate forms, creating a naturally ventilated breezeway where occupants access their homes, also avoiding the ‘sealed corridor solution’ and its associated problems of stale air and artificial light.
