The sub penthouse showstopper at 82.01/115 Bathurst Street Sydney – in  the Greenland Centre –  is being marketed with a sale expected of between $9.1 million and $10 million.

With the $400m building's completion still 18 months away, the current vendor exchanged contracts on the property in 2014 and is now relocating,  prompting a change of plans.

Mr Krasnostein said the Sydney-based owner has “nest-egged the property for the last five years however their personal circumstances have changed and they want to sell the property”.

“This three bedroom, three bathroom and powder room sub penthouse is part of the Greenland Centre Diamond Collection,” Mr  Krasnostein said.

“The apartment is truly a once in a lifetime prize which you enter via your own private lift which is solely for the residents of the Diamond Collection penthouses. “Individualised homes with the finest views in Sydney and finishes customised by your personalised consultation with marketing leading interior architect Woods Bagot. One of the tallest and the most exquisite residential towers ever to grace the Sydney skyline. “

The 67 storey Greenland Centre  is set to be completed in 2021 and includes the $35 million King Penthouse which occupies the top two levels.

The building is fast approaching its “topping out” within the next few months and the only other comparable property on the market at this time is the king penthouse located only on the floor above.

This apartment's sub-penthouse position faces north to showcase a world class view enhanced by carefully designed architectural balconies ensuring maximum visibility. The floor plan is approximately 179sqm of internal area with rooms capturing uninterrupted views over the world's most beautiful harbour city.

The towers architectural design is by award-winning architects BVN and Woods Bagot.

The residential part of the building sits on top a $25 million 2000sqm state-of-the-art five-floor Creative Hub featuring dance, theatre, music, film and visual arts facilities.

One of the most popular building to date in the heart of Sydney CBD, almost 90 per cent sold out when each stage was released to the market back in 2013 and 2015.

Mr Krasnostein is marketing the sub penthouse in conjunction with projects specialist Alex Vrisakis of Residence Property in Double Bay.
