The circular form of the building, 22 metres in diameter, resolves the complex site perimeter geometry and provides for a highly efficient development in terms of both energy and space. The internal planning squares the circle, allowing for rectilinear elements to be accommodated while maintaining optimum views and daylight right through the floorplate. Space and light are abundant despite the proximity of the building to its neighbours.
Concrete cladding elements were precast with factory-fitted glazing, and careful design detailing ensures reduced weathering and easier maintenance. The associated plant is hidden below the roof in the stepped back structure.
The flamed and honed granite flooring creates a link between the landscaping and the lofty reception area, where feature walls reflect the printing history of the site.
