The National Trust wanted to centralise four offices, supporting its activities as guardian and conservator of heritage buildings and landscapes, at a single location in a purpose-made building that would reect the organisation's culture.
This has been achieved in a design-and-build project where the Trust was the client for the design but ultimately became lessee to the owner-developer of the building.
Called Heelis, the office houses every workstation in a totally open-plan layout. Its design was driven by the desire to deliver the maximum useful daylight possible to each workspace, and to create a comfortable working environment with a minimum use of energy.
These objectives have shaped virtually every detail of what at first sight appears a rather austere structure. The sawtooth roof, for instance, is totally functional. While its north-facing windows gather glare-free light, the south faces of the roof support an array of photovoltaic cells that gather enough energy for about a third of the electricity required by the two storeys of offices below.
