The certifications fees for Green Star Homes are based on the number of product ranges (typically requiring one Designed assessment) and the Certification Assessments for each completed home.
A Product Range can also be referred to as a Standard Design. It is pre-set design that forms the basis for the home to be built for the customer. They may be allowed some design variations on this base design, but these are limited.
Fees exclude GST.
