Architecture, Building and Structure Design Komazawa Daigaku Station by Daisuke Takamiya Komazawa Daigaku is a renewed railway station located under Komazawa Park in Setagaya, Tokyo. The Under the Park concept treats the underground concourse as roots and the exit buildings as symbolic trees. Station components are grouped by three timescales: permanent earthworks, aging trees and renewing leaves. Existing tiles and terrazzo floors were preserved to reduce waste, and domestic timber was used. A metallic ceiling coating creates a dappled light effect. Benches and counters invite people to rest and to meet.
