Woods Bagot has revealed designs for the ultra-luxe penthouse interiors that will sit at the top of Greenland Centre, Sydney’s tallest residential tower designed in conjunction with BVN Donovan Hill.

Oriented towards panoramic views of Sydney’s harbour, the Bridge, Opera House and Hyde Park, three different plans have been created for the apartments across two floors.

Materiality leads the interior design, with three material and colour palettes available for owners to choose from. Named after the cuts of diamonds, Asscher is the darkest palette with a white on black feature marble. Marquise is a medium palette, while Princess is the lightest scheme. Solid timbers, marble, stone and limestone – all contrasting materials – have been selected for all three schemes.

‘Sydney balconies’ will also be featured in each penthouse, providing a seamless transition from the inside to out. Frameless glazing will block the wind while retaining fresh airflow to create a useable outdoor space.

All six penthouses will have three bedrooms, with the two larger apartments featuring additional space for household staff quarters and a media room.

Kitchens are open plan, with reflective coatings balanced with natural timbers. Gaggenau kitchen appliances are used throughout, while the kitchen cabinetry features bespoke elements such as concealed door handles.

Within the bathrooms, a marble wall will be juxtaposed against a second marble to create strong graphics on a large scale. Agape baths, differently designed in each unit, will complete the bold statement.

The 66-storey Greenland Centre sits on the former Waterboard site on Bathurst Street in the Sydney CBD, and will be the first building of its height in Sydney to graft a completely new structure on top of an existing tall building.

Five floors within the skyscraper will be dedicated to a $25 million creative hub featuring dance, theatre, music, film and visual arts facilities.
