The original brick building was designed by Brisbane Architect JP Donahue and constructed in 1936-37. The building was originally designed as a teaching space but used for administration, the main entry was central to the building which split the administration functions. The narrow nature of the building lent itself to offsetting the new internal spaces, creating an interesting cranked corridor. The existing art deco features including high ceilings, exposed beams and ornate cornice have all been preserved. The colour and lighting has been selected to pay respect to the original building.

Although the volume of existing staff room was generous, the mixed use of the area as well the level difference between the staff room and the administration functional areas proved difficult. The introduction of an internal ramp connects the two buildings and provide a large open multi-functional and flexible retreat for staff members to recharge, catch up, wind down, relax and enjoy. Collaborative working spaces, formal and casual meetings (both seated, and on the move) and small group chat spaces have all been considered in the design.
