Architect’s Introduction: “QR3D is a four-story residence, recently completed in collaboration with architectural innovation company CES_InnovFab, and is the home of Lim Koon Park, the founder and head of P+A. This residence, referred to as ‘a springboard for implementation’, is not merely a speculative experiment but a vivid proof of how 3D printing can reshape our cities.”
While 3D construction printing is not new in Singapore, it has primarily been used for small-scale and practical purposes, such as feature walls, planters, and prefabricated bathroom units for multi-residential projects. Now, P+A demonstrates how to utilize 3D printing technology to ‘print’ a building. QR3D is Singapore’s first fully functional multi-story 3D printed house, representing a leap in the application of this technology. P+A approaches QR3D with a consistent rigor, balancing bold innovation with a profound respect for form, function, and memory. The final result is a residence that proudly showcases its construction method—its layered concrete stripes retain the original texture and feel, reflecting the quality of the building process. Over 90% of the materials used in the house are 3D printed, utilizing a custom concrete mix constructed both on-site and off-site. The project’s goals are twofold: to demonstrate the practical feasibility of 3D printing in an industry known for its high risks, and to challenge people’s inherent perceptions of its construction methods. Digitally driven architecture must sacrifice emotion for efficiency.
The core of QR3D is a circular skylight—a sculptural void hovering above the dining area, filled with drama. It is not just an architectural highlight but also a silent tribute to Park’s former residence—a neoclassical house from the 1990s that once stood on the same plot. The circular skylight captures a sense of solemnity and grandeur while introducing a passive cooling system that expels hot air through hidden exhaust fans. Light filters through the circular skylight, casting shifting shadows in the circulation spaces and private rooms—Park says his favorite place is the dining area under the skylight because the light changes throughout the day.
In addition to aesthetics and emotional resonance, QR3D also redefines construction logic. 3D printing reduces labor, waste, and the need for multiple trades, simplifying the most complex architectural techniques into a seamless process. It also minimizes the environmental disturbances commonly associated with traditional construction—less dust, less noise, and less disruption. In pushing the limits of digital manufacturing, P+A has demonstrated that technology does not have to come at the expense of soul. QR3D is neither mechanical nor alien. Instead, it feels inevitable—it heralds a future of architecture that is both technologically advanced and deeply humanistic. In a vibrant urban area like Southeast Asia, such a future is imminent.
