Cabarlah House 2021

House Notes – Cabarlah House

This residence was designed with open plan living to make use of natural lighting, wide open spaces and display the amazing view over the great dividing range. With textural stone pillars framing the entry and the timber clad gable, the materials create a connection between the home and surrounding landscape. Designed by Lockhart Design, built by leading sustainable home builder Geoff Gibson Homes, and with an 18kw solar system installed by Proven Energy, the house is designed to maximise airflow and retain a comfortable temperature while using minimal energy. The owners are passionate about the environment and reducing their carbon footprint, so this recently built family home was made with sustainability in mind, and designed to help realise future plans to continue reducing the owners’ impact.

This house will be open for in person tours on 17 October. Book here.

This house achieved a NatHERS rating of 6.3 stars using NatHERS accredited software. Find out how the star ratings work on the Nationwide House Energy Rating Scheme (NatHERS) website.
