The Urban Ecologies Design Lab aims to explore socially and environmentally responsible design strategies for the contemporary city. Its mandate is to explore design in parallel with research in social science, arts and humanities and architectural history and theory. By understanding the city as interacting and evolving urban systems comprising communities, economies, environments, and constructions. Designs become hypotheses to test theoretical ideas. They adjust the way urban systems interrelate and create spaces of connections at multiple urban scales. UEDL has a strong interest in the informal high density living conditions of low-income households in East Asia, including China’s so-called villages in the city and Hong Kong’s so-called cage-homes.
