Singapore-based architecture studio ADDP has unveiled designs for two 56-story towers in Singapore that will be built using Prefabricated, Prefinished Volumetric Construction (PPVC), making them the tallest prefabricated buildings in the world.

prefabricatedNamed Avenue South Residences, the pair of towers is scheduled for completion in 2026 and will sit amongst five historically preserved buildings in one of Singapore’s most verdant areas. ADDP sought to contrast these existing, traditional structures with more modern and ecologically-conscious buildings, designed using the latest prefabricated construction techniques. 

“Its location alongside the historical KTM Rail Corridor strengthens its eclectic quality of new versus old, geological heritage versus modern concepts of live-work-play,” said Markus Cheng Thuan Hann, associate partner at ADDP Architects. 

prefabricatedEmploying the most advanced approach to sustainable PPVC construction, ADDP estimates that approximately 80% of each housing module will be built off-site, only requiring stacking and joining at the construction site. This more centralized process allows for greater control, promising to greatly reduce construction time on-site and the amount of waste produced.

According to Dezeen, the site where the Avenue South Residences will stand was selected by the government, requiring a minimum level of PPVC. This is part of Singapore’s initiative to improve construction productivity by up to 40% in terms of manpower and time savings.

“To raise construction productivity and fundamentally change the design and construction processes, the industry is encouraged to embrace the concept of Design for Manufacturing and Assembly (DfMA), where construction is designed and detailed for a substantial portion of work to be done off-site in a controlled manufacturing environment,” stated Hann.

The prefabricated towers are characterized by simple, sharp lines, and will contain over 1,000 residences broken up by a series of 16 “pocket sky terraces” and larger communal terraces on the 19th and 36th stories. According to the architects, Avenue South Residences will be in close dialogue with the surrounding area’s nature and green spaces. 

Furthermore, the north-south orientation of the high-rises optimizes solar exposure and airflow. They will also be positioned in a way to minimize their footprint, altogether forming a highly energy-efficient development.
