The land that Tai Hang Sai Estate sits on today was purchased at a discount from the government in 1961 with the intention of building rental housing for the lower income classes. It is the only privately-held low-income housing in the city. The estate is expected to be redeveloped in phases, with the first batch to finish in 2024. However, the plans have stirred resentment from many elderly residents who fear they will be evicted and have to pay a substantially higher rent elsewhere in the city.
Neighbouring Nan Shan Estate was built in 1977 and is home to about 7000 people across 8 towers.
