The new building makes use of the concrete structure of an existing 1980s office building, a two-storey rectangular volume with a simple column grid holding a waffle slab system. A new floor was added and two large circular voids, cut-off from existing slabs, for visually enlarging the experience of space and user interconnectivity, as well as bringing natural light into the interior of the building.The lighting concept responded to the interior of the building that intentionally plays on the idea of material reuse of the pre-existence. The rawness of the exposed concrete elements as well as the absence of false ceiling, thereby exposing all the electricity cable trays and AC ductwork, contrasts with the comfort and tactility of materials and finishes at users’ hands reach such as linoleum, cork, textiles and carpets. Suspended linear and functional lighting is used within the open office areas and track lighting is used throughout the circulation areas, giving a combination of diffused and accent lighting throughout the space.
