About us
CtreehouseLab leads the digital transformation of redevelopment and reconstruction projects.

Redevelopment projects run from tens of billions to trillions of won. Yet they still rely on spreadsheets and paper, with information asymmetry and opaque decision-making repeating again and again.
Through electronic voting, the Urban Redevelopment AI Chatbot, site recording, and an education platform, CtreehouseLab builds an environment where every stakeholder can take part more easily and transparently.
