Since BMW joined us as our Home of the Year partner, we have introduced a new award as part of our Home of the Year coverage: the BMW EfficientDynamics Sustainability Award, which celebrates innovation and responsible use of resources in sustainable home design. This year's winners are Pete Ritchie and Bronwen Kerr, who designed this house in Arrowtown, which is featured in our Home of the Year issue, on newsstands Monday:

As their prize, Pete and Bronwen receive a six-month lease of a BMW 320d, a diesel-powered marvel of fuel economy (using just 5.3 litres of fuel per 100km, and with carbon emissions of just 140g per km). Congratulations Pete and Bronwen.
