Hayashi Lab
Machine-translated · View original
An architectural history lab that interprets the relationship between architecture and a region's nature and history, and works to document and pass it on.

AboutAbout the lab
Turning the regional ecosphere from a constraint into a resource.
The Hayashi Lab studies the history of architecture and cities, focusing mainly on Asian cities.
It examines how cities and architecture relate to the nature, culture, and history of each place (the regional ecosphere), and works to document, pass on, and renew that relationship.
It carries out projects in Japan and abroad, including documenting modern and contemporary architecture in Southeast Asia and restoring and reusing old buildings in Oman and Miyagi Prefecture.
Key terms
- Regional ecosphere
- The set of conditions unique to a place, including its nature, culture, and history. Architecture and cities of the past were strongly bound by these conditions.
- Inventory
- A list that records surveyed items one by one. It serves as a foundation when considering how to conserve buildings.
- Kampung
- A residential area in an Indonesian city that arose spontaneously. Many date back to the colonial era.

ResearchResearch themes
Critically reexamining the course of modernity, the lab aims to build a "regional-ecosphere-based society" that treats the regional ecosphere as a resource rather than a constraint. To that end, it carries out projects that interpret the relationship between the regional ecosphere and cities and architecture, and that document, pass on, and renew it.
