Bill Dunster architects ZEDfactory Ltd is a 20 strong practice established in 1998. We have extensive experience in the design and realisation of energy efficient buildings of all types and sizes. We believe that to combat global climate change and reduce carbon emissions we need to offer more than energy efficient buildings - see our ZEDwheel in the why section of this site for our holistic design strategy. Our target is a zero carbon / zero waste society capable of running off the limited supplies of renewable energy available within our national boundaries.
