Accessibility was another priority for the project team. Wider doors and reduced thresholds, as well as allowances for the future installation of optional accessibility aids, ensures the project caters for occupants and guests with disabilities, and meets the changing needs of residents as they age. Providing stealth density in medium density areas while integrating well with its streetscape, Gen Y / Step House reconceptualises the possibilities that come when community, sustainability and affordability are equally prioritised in residential design. Its flexible housing design model also ensures it can be easily replicated in the current WA property market. The Gen Y Demonstration Housing Project is the subject of a four-year research project by the Cooperative Research Centre for Low Carbon Living and Curtin University. The research project monitors and assesses how energy-efficient design, technology performance and occupant behaviour impact energy use.
