Lifemark in New Zealand has developed standards for home design. The Handbook explains the seven areas that are important to get right at the design or renovation stage of a home. They include the minimum structural and spatial requirements that cannot be changed later without major expense. They have also included the most important home injury prevention standards because of the value of reducing the significant costs and social burden associated with home injuries.
You can access the overview and the detailed standards by going to the Lifemark Website and requesting a copy.
