Comfort, healthy indoor environment, high performance and meeting the budget were the key things we wanted to achieve when designing this home.

Being client and designer in one, we went through a few different concepts and shapes to find the most cost-effective solution that would work with the site and would position the house in a way that allows for the outdoor areas to be used in collaboration with the interiors.

Using ready-cut structural insulated panels (SIPs) in a hybrid way, we have managed to lower the cost of the build by approximately 10%, which was a major benefit.

Colorbond cladding that wraps over the first floor and covers the gutters and downpipes was one of the details that we really favoured and carefully planned. Playfulness of textures and finishes, secret passage on the upper floor, and central staircase with exposed oriented strand board (OSB) are all integral to the design. The OSB acts as a major interior feature and is a great example of how functionality can be linked with the visual perception of the space.

This house has just recently won a few BDAWA Awards:

Sustainable materials
Excavated topsoil from the previous house slab was contained on-site rather then removed and Cupolex product was used to reduce the need for creating a new sand pad and replace the engineered fill under the slab. Allowances have been made to connect the house to PV panels when budget allows and install rainwater tank in the internal courtyard for garden needs.
