More than 80% of Singapore's population live in public housing (HDB) flats located in large housing estates. Each block is considered a vertical community with common area built to promote social interaction. They have become an integral part of Singapore and their architecture is something I find alluring. One of such developments is located in Yung Kuang Road. The four blocks known as the diamond blocks were constructed in the 1970s by Jurong Town Corporation in order to house their employees. The 21-storey development escaped demolition and is currently used to house low-income families.
