Luxury apartments in the second residential tower at Barangaroo’s $4-billion One Sydney Harbour have been unveiled as they go to market.

Lendlease anticipated a strong appetite for its second offering after the record-setting sale of Residences One’s penthouse for more than $140 million, and 85 per cent of the tower worth more than $2 billion sold off the plan

Residences Two, designed by Pritzker Prize-winning architects Renzo Piano, would include 322 homes across 68 levels.

Architect Renzo Piano said the building would capture “the essence of this city”.

“The sense of transparency, sense of light, that’s why we immediately started to think about these buildings as being like crystals, playing one to the other,” Piano said.

“When you go down you find yourself in a beautiful green area in front of the water.”

With its enviable position on the harbour the buildings will be one of the most prominent features on Sydney’s skyline, standing at 235m, after an application to increase the height of the building a further 8 storeys.

Prices start at more than $2 million for a one-bedroom apartment, two-bedroom apartments will be in excess of $3.5 million, and three-bedrooms will carry a $5-million price tag.

The luxury homes with north facing views over Sydney Harbour Bridge and Opera House start at more than $12 million.

The building will also include a residents lounge, jacuzzi, steam room and sauna, internal and external pools, private dining room, billiards and wine room, gym, pilates, yoga and treatment rooms—accessed via bridges between the two buildings.

Lendlease head of residential Ben Christie said One Sydney Harbour had set the benchmark as Australia’s “most exclusive residential address”.

“We have accelerated the on-market launch of Residences Two and sales to date are going very well, owing to high levels of demand from local owner-occupiers who recognise the uniqueness of this offering as a once-in-a-generation opportunity,” he said.

“Sales to date include several large apartment purchases, with some customers seeking to amalgamate these into substantial homes.”

The first tower is due for completion in 2023, with overall completion in 2024, employing more than 1400 people.
