AboutAbout the lab
Approaching cities and towns from multiple perspectives
The Ariga Lab studies the design and planning of residential areas where people live, and the preservation and regeneration of local living environments.
The lab approaches its research from two perspectives: urban design, which links architecture and the city, and community design for local areas.
While taking part in community development projects in Japan and abroad, the lab investigates local history and residents' memories to clarify what makes a residential area distinctive to its place.
