Taichung Yingcai Road was officially handed over to the owner in 2024. The entire project took five years. The architect uses several round elements as the void space. The volume is designed with two-dimensional arcs and three-dimensional round geometric’ designs. Among them, the concave sphere is the most challenging part of the whole construction process. In this case, the fair-faced concrete subdivision system is adjusted and designed overall using 60cm x 180cm as the basic size, and the elegance of this project is emphasized with the subdivision and the slender site.
