Keangnam-Vina Co chairman Ha Jong Suk said despite the high prices and a quiet real estate market, the Keangnam Hanoi Landmark Towers had already sold 90 percent of the project's high-grade apartments.

The Republic of Korea-based Keangnam Group installed the roofs on Vietnam 's two highest residential buildings in Hanoi late last week.

Covering an area of over 46,000sq.m, the two 48-storey buildings will add 922 high-grade apartments to the market for an average price of 3,000 USD per square metre.

The 1.05 billion USD complex features a 5-star, 70-storey hotel managed by the InterContinential hotel group, offices, entertainment areas, retail spaces, clinics and convention centres.

It was anticipated to be the country's highest building and the world's 17th highest, and the 5th largest single structure in the world upon its completion until PetroVietnam announced it would build a 102-storey project in My Dinh.

Keangnam began construction in November 2007.
In a speech delivered at the ceremony, Deputy Minister of Construction Nguyen Tran Nam said the project was one of the key strategic development projects to welcome the 1,000th anniversary of Thang Long – Hanoi .

He also asked investors and sub-contractors to follow the commitment timeline and to ensure security.

The two towers are expected to become operational by the beginning of next year, with the hotel to open to guests next August.

The apartments are scheduled to open to residents in February./.
