• The Mandarin term “主要翻新计划” is a paraphrase of the English term “Main Upgrading Programme”.
  
• In 1989, the Government announced that the Main Upgrading Programme would be implemented over the following 15 to 20 years. All public flats built more than 20 years before would be included in the programme.
  
• The programme aimed to provide a more comfortable living environment and to rejuvenate the exterior of old flats.
  
• To fund this programme, the Government set aside S$15 billion from its budget surplus. Up to 90% of the upgrading costs would be borne by the Government and Town Councils, while residents would only have to pay the small remaining sum.
  
• The Main Upgrading Programme would be implemented on a consensus basis, requiring at least 75% of the residents in a block to be in favour before the works would proceed.
  
• Interior upgrading works would include replacing or adding toilet facilities, while exterior works would include renovating common corridors and adding facilities such as multi-storey car parks and children’s playgrounds.

In 2007, the Government launched the Home Improvement Programme to renovate the interiors of public housing flats that were built in or before 1986 but had yet to be included in the Main Upgrading Programme. (Lianhe Zaobao, 21/12/2019)
