Atkins provided architecture, structural engineering services and applied Carbon Critical Design to this refurbishment project for the Department for Environment, Food and Rural Affairs' (Defra) London Headquarters.

Our work on Nobel House enabled it to achieve the highest ever BREEAM rating for a refurbishment of its time. A gas-fired combined heating and power plant provides 25% of the electrical load, plus water and additional cooling. 70% of all construction waste was reused or recycled, and natural sheep's wool was used as wall cavity insulation. Nobel House was named Sustainable Building of the Year by the Royal Institute of Chartered Surveyors in 2006.
