Lost to a late 60’s classic ‘modern’ home by numerous insensitive accretions and infill was the optimism and exuberance of the period in which it was conceived. This project sought to uncover a higher contemporary value by working ‘surgically’ with the bastardised classic rather replacing it with a new build.
An iterative process was undertaken with the clients to value original elements and to explore how to incorporate or recast them into the project. New ‘installations’ were tested to determine how they might work in with the original fabric to satisfy the demands of a contemporary lifestyle; previously infilled space was carved out to create sheltered under-croft outdoor spaces; and, new connections struck between outside and inside.
The process has led to a great outcome for building and client; measured by gains in energy performance, technology, and, lifestyle.
The end result? A contemporary rebirth of an undervalued, 60’s pad.


Foremost in achieving sustainability was the clients’ embrace of a ‘rebirth’ rather than a ‘new-build’ – a decision based on aesthetic sensibilities rather than financial limitations.
Additional enhancements came from the client’s willingness to reduce the building floor area rather than building ‘more-for-more’s’ sake and to recycle elements and materials.

Innovative sustainable design elements:

Incorporated elements:

  • Louvre windows located for passive cooling and ventilation;
  • Skylights and windows placed to minimize artificial lighting;
  • Increased overhangs and high-performance insulation to Improve thermal performance;
  • Recycled building elements and materials from the site;
  • Reducing building envelope and area; and,
  • Plantation grown or managed forest timbers in new work.

Environmental footprint of the building is minimised by:

  • reducing building area by satisfying the real needs of the client as opposed to the ‘size-for-size-sake’ driving present-day houses;
  • improving insulation indices of building elements to minimize heating/cooling;
  • providing natural daylight to internal spaces;
  • providing for the manual control of ventilation in the building.
