1961: On 25 May 1961, a massive fire in Bukit Ho Swee left thousands homeless. "Operation Shift" began, in a move to place over 1000 affected families to HDB flats in Queenstown, Tiong Bahru, Alexandra and Kallang area from the relief centre. The Bukit Ho Swee area was redeveloped and flats were built in a record nine months later.
