Beyond House by Ben Callery Architects wins 2016 Sustainability Awards - Heritage prize
80 Charles Street Northcote VIC 3070
Ben Callery Architects' Beyond House was the winner of the Heritage prize at the 2016 Sustainability Awards. The expert judges noted that "it demonstrates that the heritage constraints of the building need not limit sustainability", selecting the project from a strong field of six finalists. Scroll to the bottom to see comments from our jury on this project.
Beyond House by Ben Callery Architects stretches typical terrace boundaries, making a sustainable house despite its heritage constraints.
The existing house was south-facing, dark, cold, narrow and overshadowed by neighbouring walls on both side boundaries.
The clients wanted to live more sustainably in a naturally comfortable and healthy house. Their primary brief was to get more light, sun, warmth and air into the house. They wanted to supplement passive heating, cooling and daylighting with energy efficient active heating, cooling and on site energy production.
Through the insertion of central void, adjacent to a multi-purpose studio space, opening onto a roof deck, Ben Callery Architects connected the occupants with the world beyond - sun, breezes, sky and trees. Carefully placed openable internal & external windows share light, sun and breezes between rooms and facilitate passive heating and cooling while being hidden from the heritage streetscape.
The project makes use of a 3.5kW grid interactive solar power system, rain water harvesting, energy efficient lights and appliances, water efficient plumbing fittings and fixtures, and re-milled timber flooring.

"This is a highly impressive project. It demonstrates that the heritage constraints of the building need not limit sustainability outcomes. The architect has delivered an impressive residential project with the guidance of an ambitious brief from the owners.
"Attention has been paid to renewable energy water-saving passive design material selection windows and glazing lighting and low the VOC finishes. This project is an excellent entry in the category and for the awards program in general."
