About this home

This 100-year-old semi-attached terrace was once dark, draughty and worn from generations of family life. South-facing and disconnected from its site, it had poor access to small courtyards overlooked by a neighbouring apartment block.

Rather than move, the owners chose to renovate, allowing them to stay close to family, schools and the beaches they love. The result is a light-filled, comfortable family home that feels more generous, flexible and connected to its surroundings, with space to accommodate extended family or friends over time.

Accessibility was considered in the design, with the main living spaces, a bedroom and a bathroom all on one level. While ramps and grab rails are not yet installed, a future ramp could be added from the carport to the main level if needed. A second entry through the garage also allows for more private sharing of the home.

Despite the small site, the project includes concealed rainwater tanks, high-performance glazing, strong insulation and a 7-star energy rating. An extended basement provides valuable storage and overflow space for a growing family, including a manual dumb waiter linking food storage to the kitchen.

Materials from the demolished rear of the home, including roof tiles, bricks and timbers, were salvaged and are being progressively reused. Original brickwork has been left visible and celebrated. The gardens include endemic natives, local species and edible plants, with room for chooks, a worm farm and composter. The home now captures winter sun, summer breezes and a much stronger connection to site and landscape.

This slideshow captures some of the details of the project, our process, our clients priorities, and how that resulted in a design which is more sustainable than typical homes: https://youtu.be/Lm9uI0rUDXw

Q & A

What motivated you to build or retrofit sustainably?
we're architects and this is what we believe we should all be doing - so do many of our clients.
There is no single upgrade - ie the best designs (we believe) have layers working together rather than parts sitting independently. However the most visual feature is a 2 storey landscape arbour on the southern boundary creating privacy from a 4 storey unit block next door, and creating a rich landscaped outdoor room connecting all spaces in the home. This will be more significant visually (and work as intended) as the landscapes create the outdoor room intended.
Just how deeply design can change life in a home – our clients speak to this in the movie. Before we started the process our clients were not sure that design could achieve what they needed in their existing home (eg thermal comfort, light and so on). They worried that they would need to sell and move elsewhere to achieve this.
Sky chooks! A chook pen on the green roof… (maybe that’s just us)
