[2][3][4][5] Unique amongst Housing and Development Board (HDB) projects, it is the design winner of a worldwide competition which attracted 227 entries from 32 countries.

On 8 August 2010, Prime Minister Lee Hsien Loong delivered his annual National Day message from the gallery.

An international architectural design competition was conducted by the Urban Redevelopment Authority on behalf of the Ministry of National Development between 8 August 2001 and 21 September 2001.

Subsequently, the S$279-million construction contract was awarded to Chip Eng Seng Corporation, the lowest of the bids submitted.

[17] Fully pre-cast methods were used during construction, which could be 10–15 per cent more expensive than the traditional way of pumping wet concrete all the way to the top.

Units quickly became oversubscribed with the HDB receiving more than a hundred enquiries by telephone and e-mail even before sales began.

[19] Originally set to be launched in phases, the HDB subsequently decided to release all the units for sale due to overwhelming response.

[24] The sky gardens at both levels incorporate jogging tracks, with playgrounds, rest and viewing areas, features which are unique and pioneering for skyscrapers at that time.
