The much anticipated first display apartments are now open at Waterloo's fastest-selling residential development, Waterfall by Crown Group, offering residents a luxurious private sanctuary in a lush tropical environment.

Leading Australian property developer Crown Group launched the 331-apartment luxury residential project in 2017 to near sell-out success and residents are preparing to move in from next month. Only 25 apartments are available for sale including two luxury penthouses.

Sydney buyers can now inspect the apartments in a prime location at 18 O'Dea Avenue, Waterloo, only four kilometres from Sydney's centre.

Designed by award-winning architects SJB, Waterfall by Crown Group development spans three low rise buildings and one high rise 20-storey tower. It has many natural design features including a tranquil internal lagoon, a lush rooftop escape with private outdoor cinema and tropical bamboo walk, as well as one of Australia's tallest man-made waterfalls at 22 metres high.

Residents will have access to Crown Group's signature resort-style facilities including an Infinity edged rooftop pool with a sky garden and terrace, a recreational deck, Sky Gym, rooftop outdoor Sky Cinema on Level 23, function room with a catering kitchen and music room with grand piano.

Waterfall by Crown Group Project Director Prisca Edwards said the breathtaking $395 million development had attracted buyers seeking quality of living, a sophisticated lifestyle and spectacular views in an excellent location, just 10 minutes from the airport and 15 minutes to the city or the beach.

"This is undoubtedly the best quality and fastest selling apartment development in the area," she said. "Waterfall by Crown Group is a magnificent hidden gem tucked away in lush rainforest in the city with lush tropical greenery and waterfall effect creating a beautiful and welcoming relaxing ambience.

"Two of the penthouses were sold to two buyers within a month while the third was sold recently for $3.28 million," said Mrs Edwards.

"The last two penthouses will be snapped up quickly - this is your last chance to be a part of this landmark community - living in a luxurious address at one of the most highly sought-after developments in a great location.
