In 1984, the Group moved into the forefront of international architecture with the completion of the award-winning Exchange Square complex in Central, Hong Kong.

Ruttonjee Centre and Wyndham Place were built in the mid 1980s together with the distinctive Landmark twin office towers.
In Jakarta, the practice completed the Wisma Metropolitan II in 1984, the Wisma Indocement in 1985 and Bank Negara Building in 1988 which was Indonesia's tallest building on completion.

In Singapore, Singapore Land Tower (formarly known as Shell Tower) and the Standard Chartered Bank building overlooking the Singapore River were realized in 1984.

In the late 1980s, Heinz Rust and Jim Kinoshita handed their company shares to the next generation of directors, Alan Low, Doug Collins, Peter Tse and Brian Courtenay, with Peter Tse taking over leadership of the structural engineering section. Continued expansion brought more leaders into the firm. Sern Vithespongse, Ken Lui and Bing Kwan each added their own flair and style to the company's work. They were joined by Choy Meng Yew, Dennis Tsang and Dave Yip.

The Landmark Hotel was completed in 1990 as part of a large mixed-use complex. The Westin Resort on Coloane Island, Macau followed soon after.

The company continued to be active in Hong Kong. Continuing its association with the financial sector, the Hong Kong office saw the completion of the new Standard Chartered Bank building in 1990. In 1993, it produced the iconic Entertainment Building in a highly articulated, neoclassical style.
