Stoneham Green - 11 Zero Carbon houses built to Code Level 6

Rachel worked with Radian Group right from the outset on this development, which is the first Code 6 scheme in Hampshire. Working with Gavin Board and the Radian team, she developed the energy strategy to achieve Zero Carbon and gave design advice to complete the whole Code for Sustainable Homes assessment.
