The south face of this 60-metre-long brick structure, a former warehouse, consists of a row of arches which have been left intact, but complemented by an inner skin for climate control. A strip lantern light was built into the timber roof. To achieve the requisite floor ­area, an oak-veneered volume with a gallery level was inserted in the structure, extending over two thirds of its length and accommodating introverted offices and ancillary spaces.

Access to the open upper level is via four staircases and a ground floor corridor. This volume terminates at the entrance end in a broad staircase with stepped seating. This area can be used as a small auditorium. At the other end is a kitchen and restaurant bar.
