Cheung Kong (Holdings) has sold 260 units at its Caribbean Coast phase two development in Tung Chung since last week's launch.
Senior sales manager Joseph Lau Kai-man said the firm had generated $340 million from the sale. The average price achieved was $1,600 to $1,900 per square foot.
Another 12 units in block seven would be released today at an average price of $1,609 per square foot.
Mr Lau said 896 units had been sold at a second Cheung Kong project, Vianni Cove in Tin Shui Wai, since its February launch, generating $1.35 billion.
He expected a further $300 million to be realised from the sale of about 190 remaining units in the project. Another eight units were put on sale today in its latest marketing drive.
Meanwhile, Swire Properties has lined up estate agent Midland Realty to offer new incentives for the remaining units at its Les Saisons project in Sai Wan Ho.
