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 challenge 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 usable 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 building has been landscaped to create an internal garden area.

The process of using DQI during the design phase has the added benefit of helping communicate the project
values to users, clarify design strengths and weaknesses and identify opportunities for improvement.
