Known as the 'Miller Zero' project, the development was built for real customers, as well as a project to take its supply chain, on a journey towards Code level 6 on the 3.65 acre site.

The CfSH houses are among 79 homes for sale on this development. Miller had planning permission for these houses based on 2006 Building Regulations;  but as an R & D project, it was decided to construct some of these homes to various levels of the Code for Sustainable Homes.

They wanted to know what the development costs would be between each of the Levels and additionally, how much consumers would be prepared to pay for homes created to the Code for Sustainable Homes.

Building as cheaply as possible was not a consideration for Miller, it was about achieving the different Code Levels using different types of materials and construction methods. They also realised it would be the first time that any house builder would test this decision on the open market.
