This building project is from Broadway Malyan firm, and consists of a masterplan for a 35,299-square-meter building, which will serve as Singapore’s National Heart Center. This exemplar uses sustainable technologies and features a 'floating garden' theme which can change to suit the building and its patients.

"Since the medical world sees frequent advancements, the building design makes use of modular building methods to make the architecture flexible and allow timely and untimely growth. The open architecture reduces energy consumption by allowing maximum daylight all along the concourse and the reception area."
