Let me delve into a few key moments. Back in time, when I returned to Singapore and joined the Housing and Development Board, I encountered the government’s vision of building New Towns, a concept imported from the West. However, the term “New Town” was often used without a clear definition, leading to confusion. I realised the importance of understanding these terms to avoid causing harm to people. Additionally, I became fascinated with the concept of a “Highly Self-Sufficient New Town”, which emphasised providing comprehensive facilities within a New Town, thus improving the quality of life and reducing the need for extensive travel. For both challenges, I work with my colleagues to produce well documented specifications to guide planning and development.
