A modern solar passive beach house designed for the now and into the future
This house is a thoughtfully designed, all‑electric passive solar home that prioritises comfort, sustainability, and long‑term livability through smart design rather than excess complexity.
Oriented east–west to maximise northern light, it uses high levels of insulation, double glazing, thermal mass, and careful shading to maintain stable indoor temperatures year‑round with minimal active heating or cooling.
The design features a strong connection to the garden, and an emphasis on natural light. Cleverly selected materials including locally sourced and recycled materials, low‑toxic finishes, and durable, low‑maintenance choices, support both environmental responsibility and occupant health. Solar power, battery storage, water harvesting, and efficient appliances reduce running costs and reliance on external resources.
This beautiful home demonstrates that high‑performance, energy‑efficient housing is achievable within a moderate budget when design is placed first
FEATURES
Passive solar orientation and design:
The house is oriented east–west with strong northern exposure, deep eaves, and thermal mass to maximise winter sun and minimise summer heat gain, resulting in stable indoor temperatures year‑round.
High‑performance building envelope:
It includes very high levels of insulation to the ceiling, walls, subfloor, and garage, along with double‑glazed, argon‑filled, low‑e timber windows and doors to reduce heat loss and gains.
All‑electric renewable energy system:
The home operates without gas, using a 6.6 kW solar PV system, an 11 kW battery, and an electric heat‑pump hot water system powered by solar energy.
Water efficiency and rainwater harvesting:
A 7,000‑litre rainwater tank captures most roof runoff and supplies toilets, laundry, and the garden, supported by water‑efficient fixtures and a water‑wise native landscape.
Healthy and adaptable living features:
The house incorporates low‑VOC materials, excellent daylighting, consistent internal temperatures, and universal design elements such as step‑free access, wide doorways, and adaptable wet areas for long‑term living.
