Refurbishment of HM Treasury has breathed new life into a Grade 2* listed building.

The new accommodation brings the Treasury staff together in one building. The design hallenge was to remodel the building to make use of the myriad corridors, unused light wells, staircases and unproductive spaces whilst remaining sympathetic to the heritage constraints.

The result is a flexible, modern office space that delivers significant environmental and energy saving gains. The refurbishment has provided an extra 25 per cent of useable space for 1,200 staff; views through the building have been improved thanks to transparent roofs and light wells and a large courtyard at the centre of the mbuilding has been landscaped to create an internal garden area.
