There are 2 categories of flats in the  Tiong Bahru  Estate and these flats are split up into 2 sections within the  Tiong Bahru  Estate. » link

The  HDB  Post War flats are rather angular and the shapes are very standardised. Some people  always refer to it as the ones with the round balconies. » link

These flats were built from the 1948 - 1951 period. It was built by the Singapore Improvement Trust (SIT). Some people refer these flats as the  LIM  YEW HOCK flats but I do not think they are built during his reign as Chief Minister of Singapore as he only took office in 1956. » link
