Mount Stuart Greenhouse

Address provided prior to event


Architects: Bence Mulcahy

Culverden is a highly-crafted Federation Italianate style house in Mount Stuart with an expansive garden. The new owners’ design brief was for their home to be ‘engulfed by their garden’. The result is a striking two-storey green-house style glass extension, with a private suite contained in a floating box.

Growing from the existing, traces of the new present themselves by degrees, culminating in the kitchen and dining area where the full extent is revealed. It shares formal characteristics with the existing sandstone base, yet is transparent and overtly structural, capturing the gardens proximity and formally setting up a relationship with the existing verandah. Generous volumes capture the scale of the immediate vegetation and views, and crafted details and materials provide continuity of pattern and texture. Natural materials develop patina and contribute to a lived-in space. The Mount Stuart Greenhouse provides a stage for family life connected to the garden and verandah, in a manner complimentary to the quality and craftsmanship of the existing home.

The Mount Stuart Greenhouse won the 2019 Australian Institute of Architects Roy Sharrington Smith Award for Heritage, Award for Residential Architecture (Alterations and Additions) and the COLORBOND Award for Steel Architecture.
