Solstice

Finalist in three categories of the 2026 HIA ACT / Southern NSW Housing Awards: Custom Built Home $2 million to $4 million, Coastal Home, and GreenSmart Sustainable Home. Winners are announced at Parliament House on 23 October 2026.

Solstice was also shortlisted as a finalist in the Custom Built Home category of the 2026 HIA Australian GreenSmart Awards, the national program recognising environmentally responsible homes.

Depot Beach sits beyond the reach of town water and mains sewer, so self-sufficiency wasn't a feature to add on: it was the brief. Architect Peter Ireland answered that rather than worked around it, with a home that makes its own power, captures and stores its own water, and treats its own wastewater on site.

The result runs almost entirely off grid: 60,000 litres of onsite rainwater storage, a 20 kW solar array with an 11 kWh battery to carry the household through the night and the quieter months, and an onsite sewage management (OSSM) system that keeps everything contained and treated on the property.

Perrem works two ways: on our own in-house designs, and alongside an architect the client brings to us. Solstice is the second. Our job was to take Peter Ireland's design and deliver it, resolving the servicing that makes an off-grid home actually work, so the house that was handed over performs the way it was drawn.
