The natural light of this space is exploited fully on both levels. Due to its position on the uppermost two floors of this building, and the sweep of windows on the external face of the lower level, light floods through the space. In addition a sliding glass panel in the roof is positioned so as to produce a shaft of light which permeates past the galleried upper level through to the lower. The orientation of the upper level is directed by the wall of sliding glass doors which open onto the roof terrace and a view of the cityscape.
