Greenland Centre will be the highest residential tower on the Sydney skyline, comprising 480 luxury apartments over 67 levels and 11 levels of car parking.


Located on the corner of Bathurst and Pitt Streets in Sydney’s central business district, Greenland Centre will be the first building of its height in Sydney to graft a completely new structure on top of an existing tall tower.


The development consists two distinct buildings with heritage significance – one of them a tall tower, onto which the new tower is grafted. The other is the heritage-listed Water Board building, which was converted into a boutique hotel known as the Primus Hotel.


The building will also have unique Sydney balconies with a façade of modulating angled glass to compensate for the wind levels at height. This creates winter gardens that can be used all year round.


Performance and Value

We are providing fully integrated building services for the entire project. Transforming an existing office building so that it is fit for residential use creates unique challenges. We have also had to implement strategies to guarantee adherence to rigorous regulatory requirements for indoor environment quality, while ensuring no compromise on aesthetic design.


The team created a fire engineering solution that eliminated the stair pressurisation system from the building, replacing it with strategic lobby smoke ventilation. This reduced the riser space required and provided significant capital costs savings for mechanical plant.


To achieve acoustic separation requirements in accordance with the Building Code of Australia, our team increased performance of existing floors and flanking around built elements. In doing so, we addressed many of the challenges of converting former office space into residential space.


Tangible Benefits

Through detailed analysis, innovative design and close consultation with the architect and façade engineer, we successfully adhered to the rigorous regulatory requirements for the project and still delivered on budget. The tower is due for completion in 2020.
