Energy-Efficient Homes From Day One
Every B1 home includes energy-efficient features as standard.
✔ 6-Star Energy Rating Included
All our homes meet or exceed the 6-Star energy rating, reducing heating and cooling costs while improving year-round comfort.
✔ NCC 2022 Compliant
We build to the latest National Construction Code, ensuring your home meets modern energy, thermal, and performance standards.
✔ R4.0 Insulation Throughout
High-performing insulation to the home and garage (included as standard) maximises thermal efficiency.
✔ Energy Efficient Appliances
✔ Renewable Timber Construction
Timber is one of the world’s most environmentally responsible building materials. It is renewable, stores carbon, and has significantly lower embodied energy compared to steel or concrete.
B1 Homes uses:
- Timber roof framing
- H2 treated blue pine for strength and durability
- Materials selected in alignment with the sustainability values of Sumitomo Forestry
This gives homeowners a lower-carbon construction method without sacrificing strength or performance.
Sustainable, Durable & Low-Waste Materials
We partner with suppliers who prioritise long-term durability and responsible material production, including:
- Laminex (responsibly sourced, long-lasting cabinetry materials)
- Colorbond (thermally efficient and 100% recyclable steel)
- Midland Brick (sustainable manufacturing practices)
By using materials designed to last, we reduce long-term waste and help your home remain low-maintenance for years to come.

Included as standard:
- Energy-efficient instantaneous hot water systems
- Reverse cycle air-conditioning options from leading brands

Less energy in, greater comfort out.
