Inspired, imaginative and immaculate, 240 Duffy Street Ainslie is the most uniquely sustainable house in Canberra making it immensely comfortable to live in and a home to be proud of.

Designed for living in harmony with one’s surroundings, this is a home that extends beyond the front door; to integrated gardens, the foothills of Mount Ainslie Nature Reserve and the wider community of the Inner North, with the principles of environmental consciousness at its heart.

The first of its kind, the product of a vision to push environmental boundaries and a desire to contribute in a positive manner to the real issues surrounding water, energy and climate change. The has proven that it is possible to create a self-sufficient, sustainable family home in a residential setting.

Architecturally custom-built to high specification, the home is an early adopter of eco-friendly design. Entirely solar-passive, perfect northern orientation and thoughtful garden design enhances winter sunshine and summer shade, the residence is meticulously crafted for year-round comfort.

The seamlessly integrated filtration system and 90,000L tank fully supply clean, fresh water, which in turn passes through a grey water recycling process and reed bed for re-use in the garden. The home stands alone by its innovation and its carbon neutral footprint.

Set amongst the leafy backdrop of Mount Ainslie, the integral relationship between house and garden speaks to the civic-mindedness of the original Canberra suburbs. The ethos and principles of permaculture underpin the impressive kitchen garden, over 100m2 of seasonal vegetables and herbs planted in the extensive vegetable gardens. Citrus, stone and orchard fruits adorn the block in over 35 varieties across 40 individual trees, kept in company with berry plantings and flowers.

Enjoy fresh pizzas from the custom-built pizza oven with family and friends on the recently paved area or under the wide verandah providing protection from the elements. Taking in the greenery and fresh air, picking aromatic herbs in Spring sunshine, sharing delicious meals from garden to plate with loved ones; an inspired, joyful and connected way of living.
