The colour and material palette of the gallery is muted, mainly comprising white-painted, coffered concrete slab ceilings and plasterboard walls, large expanses of sand-coloured concrete walls and travertine floors. Differing floor finishes are important to the functioning of the galleries: substantial areas in general traffic zones are finished with large travertine slabs; travertine also runs in narrow bands along walls as a deterrent to touching the paintings; timber parquetry is extensive. The building retains original furniture designed by Robin Gibson and Partners.
