This house is currently under construction, please take care on site

This hempcrete house in Narara Ecovillage, incorporates a multitude of design features ensuring that not only does the building meet all of the Ecovillage’s rigorous sustainability goals and guidelines, but also creates a very comfortable and liveable home for its owner.

The 130sqm three bedroom house sits on a sloping block with views across the valley. The single storey house is split over two levels to follow the natural slope of the site. The upper level has a burnished concrete slab floor, which provides thermal mass to help regulate temperature, while the lower level has a timber framed floor.

In addition to the thermal mass provided by the concrete slab, a 5m long rammed earth wall runs through the centre of the building. Both the rammed earth and concrete slab enjoy long exposure to winter sun, through extensive north facing double-glazed aluminium-framed windows and doors.

The external walls of the home have a timber framed structural core at the centre of the hempcrete, which then provides the insulation and breathability.

Designed by Envirotecture and being built by eBuild and Consult

 

This house achieved a NatHERS rating of 8.8 stars using NatHERS accredited software (AccuRate). Find out how the star ratings work on the Nationwide House Energy Rating Scheme (NatHERS) website.
