About this home

Our Hazo Hempcrete House was the fifth Hempcrete house to be constructed in the Blue Mountains and is a joy to live in. Comprised of two pavilions joined by a covered walkway the property features native gardens at the front and rear and a mix of native and fruit trees in the central courtyard. It is an outstanding example of solar passive design principles, using only ceiling fans for cooling and a hydronic floor heating system for overcast winter days - on cool sunny days the double glazed windows and 250mm thick hempcrete walls enable the house to heat itself!

By May we hope to have some data on the performance of a 20 kW solar system and a 1Komma5 38.5 kWh battery and be on our way toward energy self sufficiency.

Although we are not in a rated fire zone, in the Blue Mountains nobody is safe from ember attack and we hope to set an example by showing what a fire resistant Hempcrete house can look like, and how comfortable it is to live in.

Q & A

What motivated you to build or retrofit sustainably?
We really wanted to show how it is possible to live comfortably in a climate-conscious, energy-efficient and bushfire resistant hempcrete home.
Solar passive design is the key principle behind our place!
Make sure the landscape plan is prepared and any necessary excavations executed at the start of the project! (And if you are using a box drain, make sure it is installed with the correct slope!).
Knocking down the Fibro tent next door and building 3 or 4 hempcrete tiny homes!
