NatHERS (Nationwide House Energy Rating Scheme) is a star rating system (out of 10) that rates the thermal efficiency of the home’s design. In other words, how well the house can stay at a comfortable temperature throughout the year without artificial heating or cooling. Every Ecovillage home must achieve a minimum of 7 stars.

WARDAN – $POA
DESIGNED by design BUTTON; built by Kerrigan builders
Wardan means ‘the sea’, so Wardan Boodjar means ‘sea country’ or the coast anywhere in the South West. Wardan is of great spiritual significance to the coastal Nyungar.
Constructed from hempcrete and timber framed external walls, this large, barn style home was designed to house a large family. It takes entertaining to the next level with an outdoor kitchen area in the spacious alfresco, which protects the western side of the home while also allowing connection to the communal space. Openings are placed to allow good air-flow, keeping the home fresh at all times. Universal accessibility has been considered in detail throughout, making this home perfect for independent living. The vertical and horizontal thermal mass will assist in minimising temperature fluctuations internally throughout the year. Ensuite and bathrooms are located north with a full height window to the shower, keeping the areas comfortable and mould-free naturally all year round.

Ecovillage Pre-designed Homes consist of two wholly separate contracts: for the land and the house.
- Buyers must purchase and settle on an Ecovillage lot first from the developer, Sustainable Settlements. If you need finance, you’ll need to apply for a separate loan from a financial institution for the land.
- Buyers then enter into a separate financial agreement and building contract with their chosen builder. Sustainable Settlements (the Witchcliffe Ecovillage) is not involved in this process. So regardless of whether you opt for a bespoke design and build or you choose a house design from our range of Pre-designed Homes, you will need to work directly with your builder and your financial institution during the home building process.
Documentation and Certifications
Life Cycle Assessment (LCA) is an excellent method for measuring the environmental impact of a building by assessing “every single impact aspect of a product or process over its entire life span. We require every Ecovillage home to undertake an LCA. Read more about Sustainability Assessments here.
The Ecovillage Design Team requested its guild of builders meet the minimum requirements outlined in this General Specification Schedule as part of their tender pricing process for Ecovillage homes. There will be variations in the materials, suppliers and pricing they have assumed for certain items. Consequently, we strongly advise you to discuss the specification schedule and associated pricing of your chosen home in detail with your builder so you understand exactly what is being built.Download Specification schedule
