They share their principles behind the groundbreaking design and their favourite features.

Synopsis: The Straits Times speaks with experts to discuss how public housing design has evolved in Singapore.

Public housing is all around us. They are in older towns such as Queenstown and Toa Payoh, and in newer ones like Punggol and Bidadari. Eight in ten Singaporeans live in HDB flats.

How has the design of HDB blocks evolved over the decades? What has worked out and what hasn't?

ST's housing correspondent Michelle Ng speaks with Dr Liu Thai Ker, widely known as the architect of modern Singapore. This is because he helped to plan 20 out of the 24 HDB towns in Singapore during his time from 1969 to 1989.
