Australian property developer Crown Group has announced that it will be releasing the three penthouse units at Mastery by Crown Group, its latest project in the Waterloo suburb in Sydney.

The penthouses in the $500 million project will have views of the city and the surrounding suburbs of Zetland and Green Square. Mastery, developed in partnership with Mitsubishi Estate Asia, will comprise 374 apartments in five residential blocks. The penthouse units are located at the top of a 19-storey tower designed by Japanese architect Kengo Kuma. Mastery is his first residential project in Australia.

The penthouse units are sized from 1,615 sq ft to 1,841 sq ft, and will be priced from A$3.75 million ($3.63 million) to A$4.88 million. Units will come with high-end kitchen and bathroom finishes and appliances, such as premium Smeg rangehoods, gas cooktops, ovens, steam ovens, microwave ovens and coffee machines. Buyers may also have a Japanese onsen-style bathtub in their ensuite.

Other units in the development include studios and one- to three-bedroom units priced from A$630,000 to A$2.37 million. Mastery is expected to be completed in 2021.
