When Ngee Ann City opened in 1993, Tangs Studio (a division of Tangs) occupied three floors of the building at the Tower B section of the building. A few years later, Level 2 of the department store was closed in 1999 due to poor business. This part of the mall became part of the speciality shop section (mainly branded boutiques) on the mall on Level 2, Books Kinokuniya on Level 3, and a shop section mainly children's boutiques and shops on Level 4 that was converted to iForum in 2005. The top floor of the mall, Level 5, was part of the upper level carpark. In 1997, the 5th floor was converted to retail space.
