In the late 1970s, Tang expanded his business again when he decided to develop the neighboring property lots which he had bought years before. In 1982, the building on Orchard Road was demolished to make way for the new Tang complex, comprising the 33-story deluxe Dynasty Hotel (now the Singapore Marriott Hotel) and the Tangs shopping complex (now Tang Plaza). The shopping complex consists of five floors of retail space covering more than 15,000 m², marketed under the slogan "All The Best Under One Roof".
