ββββThe principles of Universal Design are to design houses to be as useful as possible to as wide a range of people as possible over their lifetimes. It includes people with a wide range of different abilities including (but not limited to) people in wheelchairs.
The fundamental principle is to make a home that can easily be adapted to suit the changing needs of the occupants as they progress through life. It is accepted that not all homes can incorporate all of the universal design principles, and they may have to be balanced with other design outcomes. However, if the house incorporates one or some Universal Design principles, it will be a better designed, more functional house than if it incorporates none.
Auckland Council uses the Lifemark Design Standards Handbook to assess the universal design quality of homes. A three star rating is the minimum to ensure a home incorporates universal design principles.
