Holocene House: Australia's First Active House Certified Home

Holocene House, located in Manly, Sydney, exemplifies sustainable residential design by seamlessly integrating natural elements into its architecture. Designed by CplusC Architects + Builders, the two-storey home features a natural swimming pool that flows through the property like a rainforest creek, with every room opening to the outdoors. A canopy of plants envelops the structure, enhancing its connection to nature.

The residence is Australia's first to receive certification from the international Active House Alliance, reflecting its commitment to balancing environmental performance with occupant health and comfort. The design incorporates renewable energy systems, rainwater harvesting, greywater recycling, and low-impact materials throughout.

The homeowners, a young couple with two children, aimed to create a carbon-positive sanctuary. By 2050, the home is expected to have generated more energy than was consumed in its material production, construction, operation, and eventual disposal.

The landscaping includes native plants to support local ecology, a productive fruit and vegetable garden, and a chicken coop for self-sufficiency. The natural swimming pool, cleansed by a biofiltration system of polishing ponds, reeds, charcoal, and pebbles, serves as the heart of the home, fostering playful and rejuvenating family spaces.

Holocene House has been recognized for its innovative approach to sustainable living, winning the Single Dwelling (New) category at the 2024 Sustainability Awards. The jury noted that the design prioritizes regenerative thinking and sustainability over size.
