A Sydney home with the ultimate extension is on the market with a price guide around $50m.
A Sydney house with an epic extension complete with a harbourfront gym, secret library and a squash court, is tipped to become the most expensive house west of the Sydney Harbour Bridge.
The nine bedroom waterfront estate on Poole St in Longueville, known as Otahki, is on 4400sq m of land with a price guide of $49.5-$53m.
Forbes Global Properties – Double Bay agent Ken Jacobs described the home as “very special” and said interest in the property had been “extraordinary” since it hit the market with the owners looking to downsize.
The home has a price guide of $49.5m – $53m.
A glass walkway connects the original to the new home.
The home also features its own squash court.

The original anti-bellum style homestead was built back in 1938 and has only had two owners.
The first owners built the homestead and held onto it for 70 years, while the latest owners are behind its “astonishing new chapter – under the direction of one of Australia’s most highly acclaimed architects, Ian Gross”, according to the listing.
The extension is nothing short of epic – with a modern home built and connected to the original home via a glass walkway.
The original home has become the foyer, gym and library.

The home has a pool along with a second full sized lap pool.
What a view.
“Its owners will tell you their proudest achievement with this home is that they knew all their children friends, because they always spent their time here,” the listing says.
“It’s a very light, easy and flowing environment – with lovely languid curved walls, vast tracts of hand-picked and slow cured American oak, and immense glass walls and doors that are a window onto those glorious surrounds – the enchanting Japanese-inspired gardens, the picturesque stretch of harbourfront, and on the skyline beyond, the city laid out in all its glory.”
With standout features such as a harbourfront gym, secret library, two pools, squash court, cabana, jetty, landing steps and boathouse, you can see why it’s described as a “world of its own”.

The main house has five bedrooms, eight bathrooms, central kitchen, and a variety of living spaces.
There’s also a private office wing, stand-alone guest quarters, cellar and full caterers kitchen.
“Being here is an amazing experience and there would be very few homes along the shores of Sydney Harbour to rival its scale, its quality, its vision and the calibre of life it offers,” the listing says.
“A world class family home for a world class family life.”
Mr Jacobs said Longueville was playing catch-up and seeing a recalibration of its property values and added that buyers from overseas, the lower north shore and the eastern suburbs are all looking at Otahki.
