Bam Construction has been awarded the contract to build Network Rail's £120m national headquarters in Milton Keynes.
Construction of the 400,000 sq ft development will start next month.
The new National Centre will boast strong environmental credentials, and has been awarded a BREEAM Excellent design stage rating.
The development will take advantage of a range of measures designed to regulate temperature and reduce energy use, including optimising the building’s orientation and facade, narrow floor plans, high overhanging soffits to provide shade, and natural ventilation which are all complemented by very high efficiency, low carbon systems.
The National Centre will also include extensive ‘living’ roofs to greatly enhance and encourage diverse habitats for flora and fauna, and sizable rainwater harvesting systems will be used to flush toilets and irrigate the plants.
Material will be recycled from the National Hockey Stadium which used to occupy the site, with other materials sourced as locally as possible to help limit the number of lorries and further reduce the development’s carbon footprint.
The National Centre, which will house 3,000 employees, will save the rail infrastructure operator £20m a year through savings on office rent elsewhere.
