Lim Kim San DUT (Chinese: 林金山; pinyin: Lín Jīnshān; 30 November 1916 – 20 July 2006) was a Singaporean businessman, civil servant, and politician who served as a Cabinet minister with a variety of portfolios between 1965 and 1981.

[6][7] During the World War II, Lim was tortured by the Kempeitai, and was labeled as communist and British sympathiser by occupying Japanese forces.

[9] Overseeing reservoir development and expansion, Lim served as Chairman of the Public Utilities Board following appointment in 1970.

A committee was eventually set up under Lim Tay Boh to find out whether the HDB had the capability and the materials to reach the construction goal.

The largest project at that time was Queenstown, a satellite residential area of more than 17,500 flats, capable of housing close to 22,000 people.

This philosophy—which was ultimately extended into modernity with the planning concept of the New Town was meant to lower the rate of congestion and burden on the central business district.

The overall cost was also kept low by employing a large pool of contractors and sourcing building materials from a variety of vendors.

[8] Following convincing from Prime Minister Lee Kuan Yew, Lim contested in the Cairnhill constituency as a PAP candidate during the 1963 general election and won 7,749 out of the 11,659 votes.

As a mark of respect for Lim's contributions to the country, State flags at all Government buildings were flown at half-mast on the day of his funeral.

[17] In June 1962, Lim was awarded the Order of Temasek (First Class), Singapore's highest civilian honour for his service in the Housing Development Board.
