Bank Negara Malaysia commissioned this complex to house a centre for international collaboration in financial-sector development, as well as a museum of numismatics and an art gallery to display its collections. Set back from the street and surrounded by lush landscaping, the building’s 200-metre frontage is divided into three linking pavilions on pilotis and a central grand foyer. Its orientation and the recessed sections of the facade assist natural climate control. The site plan takes the form of a cowrie shell, the earliest form of Southeast Asian currency; and the diagrid facades recall 'songket', a traditional Malay brocade. A notable interior feature is the museum’s nautilus shell-shaped staircase.
