Five additional levels of office space were added while the tenants in the 18 level tower remained in complete occupation.

Gray Puksand was engaged by BCL to undertake a Feasibility Study reviewing the programming, constructability and costs of an additional five levels atop their existing 18 level tower in the CBD. Upon approval of the project feasibility, our team was appointed as Principal Consultant (Architect) to work closely with the client group to design, document and undertake contract administration for a total addition of 4,500sqm of office accommodation.

A key aspect of the planning, design and construction process has been our clients requirement to maintain day to day operations of the building and its services, including vertical transportation, egress and to minimise disruption to the 500 barristers occupant within the building. During subsequent development of the construction program, potentially disruptive works were identified, analysed with the client group and determined as required to be undertaken by the contractor out of hours.


A lightweight building structure of steel and precast Hebel Plank was chosen as it has permitted a more effective floor to floor height which has allowed the addition of five levels in lieu of only two that would have been possible should traditional concrete slab construction been utilised.
