View descriptionShare

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?

They are the design duo behind the groundbreaking Pinnacle@Duxton in Cantonment Road, the first 50-storey public housing project in Singapore, and also the first one in the world to have two sky bridges linking the seven towers that it comprises of.
