Avenue South Residences

Designed by ADDP Architects, the 988 apartments in these two Singapore skyscrapers will be assembled like a Lego set, with teams using nearly 3,000 vertically stacked modules that snap together. Factory-made, concrete-cast modules will be made in Malaysia, then fitted and furnished at a separate facility, then assembled at the building site. The firm estimates 80 percent of the work on each module will be completed off site, minimizing disruption to businesses and allowing for greater social distancing measures during construction. Upon completion in 2026, the prefab towers will nab the title of world’s tallest modular construction for developers UOL Group Ltd. and Kheng Leong Co.
