This building is the transformation of an early twentieth century warehouse into an office building with a central atrium. The atrium is lit with a Passive Solar Optical system which delivers bright, diffused sunlight down seven levels to the entry atrium floor. The sunlight is optically contained within the atrium area during most of the working day.
