Mammoth Projects was engaged by Grosvenor Place to coordinate a flexible ‘rolling’ refurbishment across nineteen floors of the well the iconic Harry Seidler Building along with the refurbishment of six floors of the adjacent heritage-listed Johnson Building.

The scope of work involved a complete strip-out, back to the base building structure and refurbishment of each floor. With a focus on Amenity within the building, a new lobby and toilet refurbishment was undertaken, utilising premium stone and stainless steel finishes. 

Mammoth carried out the work while the remainder of the 45-floor building remained occupied and operational. Materials handling was a significant challenge and required the project team to develop a tailored methodology to ensure minimal disruption to the tenants and the day-to-day activities in this busy CBD location. Numerous tenant fit-outs occurred simultaneously during the works.

Remedial work was needed for Grosvenor Place’s structure and the installation of several energy-efficient initiatives. Mammoth included air conditioning upgrades and fire services upgrades in the works to achieve best practice sustainable development.

Mammoth worked closely with project partners Grosvenor Place Management & Engineering, Harry Seidler & Associates and VOS Group during all stages of the work to set a new standard for one of Australia’s much-loved buildings.
