Our hempcrete home is the fulfilment of a long held dream to design and owner-build a home with sustainability and longevity in mind. We used passive solar design principles, invested in a well-sealed building envelope including the hempcrete and made the most of the beautiful aspects of the hills wherever we could. Our previous home was a 120m2 weatherboard with gas heating, hot water and cooking. This house is 185m2 and all-electric, but our electricity usage here is less than the last house! What a difference good orientation, insulation and energy efficiency makes! The house is built to BAL29. Owner-building was a challenging but rewarding journey, supported by so many generous family and friends.
