About
About us
CtreehouseLab is an AI technology company that grounds redevelopment decisions in data rather than instinct or bias. Redevelopment and reconstruction is where it starts.

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.
Electronic voting, the Urban Redevelopment AI Chatbot, site recording, and education — each domain solved by a dedicated solution, expanding into project operations and cost management to refine and elevate decision-making and operations across redevelopment projects.
