RE/MAX Lighthouse Realty have found that modern, educated and younger demographics are leaning towards house with smaller footprints. Not only can this provide more garden and outdoor area on a smaller block or more overall public open space in a development, but it has also resulted in a lower carbon footprint for this design.

A saving of 52% is expected to be achieved with this design giving the building an overall Silver Medal rating. This smarter, smaller house represents a fantastic alternative to current ‘business as usual’ new free standing homes.

Project features

With better use of space, materials and construction techniques this design has been able to show that affordability and sustainability go hand in hand. By going up a level this home maximises the use of available space and allows for more garden and out door area. Not only is it quick to construct, the affordability nature makes it a great design for most developments.

The eTool assessment showed that the true Life Cycle carbon footprint of this design was a far improvement on the “Business as usual” designs. Thus enabling the developer to present a good argument for design approval where local councils are resistant to any designs progressive in nature.
