Studio

eco-id is an architecture and interior design practice founded in Singapore in 1996, with studios in Singapore, Bangkok, Shanghai and Skopje, and projects across Asia, the Indian Ocean and Africa.

The name joins two ideas. Eco means reading a site's context closely. Id means giving each project its own identity, drawn from its climate, location and landform.
