Building With Hempcrete

and other sustainable building materials.

Building for the future with eco-friendly materials

At Homes By Nature, we build homes using sustainable materials such as timber frames and traditional cladding or Hempcrete, with Hempcrete being our preferred building method.

Outside the Witchcliffe Ecovillage, we can build with steel frames if you prefer.

Feel good about your new home and build for your future using Hempcrete.

What is hempcrete?

Hempcrete is a highly energy-efficient and eco-friendly building material that can reduce the running costs of your home. Together with solar passive design and double glazing, Hempcrete is one of the best insulating materials on the Australian market. Imagine not having to turn on your air conditioner!

Reduce your power bills, save your money and invest in our future.

Hempcrete is made from the inner woody core (or ’shiv’) of the hemp plant mixed with a lime-based binder. This creates a lightweight, permeable, insulating material superior to concrete. It can be applied to a lightweight timber structure and rendered or painted once cured.

Hempcrete can be applied in situ or by mechanical spray. In situ installation can be labour-intensive, as it involves vertical layering of the product. However, it creates a visually attractive finish. Hempcrete has a very organic, relaxing and earthy appeal when left exposed. It’s a fantastic feature that pleases the eye in any home.

Applying Hempcrete using a mechanical spray is more efficient as it can be applied directly to walls. Only one side of the wall needs to be sprayed, saving waste, time and labour. Mechanically sprayed Hempcrete is usually finished with a render and then painted. Rendering with lime render creates a durable product with excellent thermal, sound and fire-resistant properties.

Installing Hempcrete by mechanical spray is convenient, fast and affordable.

Hempcrete does not contain volatile organic compounds. No chemicals are added during production and it does not release gases or toxins. It is hypoallergenic and does not trigger allergies or respiratory illnesses. Therefore, hempcrete is a safe building material for people and pets.

Hempcrete is also highly fire resistant, protecting you and your family. It will not spread in a contained environment and increases your escape time during a bushfire.

This makes hempcrete is one of the safest building materials in the world!
