Stonehenge Lodge is a permanent architectural installation composed of ten inclined concrete volumes in Zhubei, Taiwan. Redefining the short-lived sales center as a civic framework, it hosts evolving programs like a bakery, exhibitions, and gatherings. Built entirely in exposed cast-in-place concrete with no secondary finishes, each volume required precise formwork geometry and one-time pours to achieve seamless joints, slope accuracy, and surface integrity. The building offers adaptable, open interiors and passive light and ventilation, reducing both material waste and operational carbon. It proposes architecture not as display, but as a quiet urban presence that listens, endures, and remains.
