The estate is one of the Society's Sandwich Class Housing Scheme projects converted to private developments. It was sold to the public in early 1997 at a discounted price of HK$2,700 per square foot, compared to the HK$4,000 market value at that time. In 1996, the Hong Kong Housing Society had received 6,520 applications for the purchase of a batch of 1,696 units in Radiant Towers and Marina Habitat.
Radiant Towers was completed in 1999, after the project was delayed because of the bankruptcy of one of the contractors. It comprises two 47-floor residential towers, offering a total of 704 units.
