We should empathise on Singaporeans and PR's who are currently living in Singapore. Most Singaporeans are unhappy and complaining about the the shrinking housing units as compared to during the 1970s.
Below is a table that shows a decrease in household size over the decades.
Figure 2.0 HDB Flat sizes and Household size over the decades
As you can see from the table during 1970s to latest, the design norms decreases over the decades. The reason for this decrease is due to shrinking of household size and limited land space in Singapore. However, these decrease did not affect the quality of housing units as stated by the Housing Board. The stakeholders can be students, working adult without a housing unit, working adult with a housing unit, a family with children and so on.
In conclusion, it really depends on how an individual see a living space and when really living under one.
