In addition to solo practice, Nishi actively engages in collaborative projects that construct phenomena through shared perspectives.

At the Space Production Laboratory, fluid team formations enable multiple viewpoints to intersect, generating layered phenomena unique to collective creation. In duo projects with OSOTO lab., natural phenomena such as light and wind are treated as shared materials, with space designed as a site of dialogue.

These works demonstrate how collaboration expands the interpretation of phenomena, allowing Phenomena Architectureto evolve beyond individual philosophy into socially and relationally engaged spatial practice.
