The 5×4 Hayes Lane Project is a unique, inner-city dwelling set on a tiny footprint – 5×4 meters! The entire build is designed, built and powered with passive and active eco-driven processes, materials and performance considerations. The 5×4 Hayes Lane Projectdemonstrates and encourages discussion around sustainable living, a healthy form of densification in the city of Melbourne and how to achieve it through best practice design and living. It uses the One Planet Living®principles as its guide for the physical design of the project, adaptation around behaviour to reduce ecological footprints in a city, and acts as a platform to disseminate progress and learnings from the process. The project featured on Episode 4 Series 8 of Grand Designs Australia. www.fivexfour.com
