Riddle, Rubble, and Ripple Part 2 Project 2025 Jihoon Baek The Bartlett School of Architecture, UCL | UK Grounded in the reality of inequitable leisure provision on Metropolitan Open Land, this project aligns with the UN Sustainable Development Goals - focusing on sustainable cities, climate action, and reducing inequalities.Riddle, Rubble, and Ripple proposes a long-term reimagining of Metropolitan Open Land along the 29km River Brent corridor, beginning at the abandoned Gurnell Leisure Centre in Ealing. Rooted in the Latin licere (“to be allowed”), it questions who is afforded access to urban nature and challenges the fragmentation of London’s public open space.Drawing on collective memory and histories of flooding, the project reframes floodplains as civic infrastructure. It addresses the ‘riddle’ of controlled ecologies, reuses the ‘rubble’ of neglected land and infrastructure, and sets off a ‘ripple’ of flood-responsive leisure landscapes to serve over 200,000 residents.Conceived as a phased 20-year strategy, it uses biosolids from on-site decontamination in a regenerative material approach. Existing fragments are redistributed for future adaptability, shaping spaces for play, rest, and stewardship. The floodplain becomes not a crisis edge but a living terrain - amplifying local agency, enabling equitable access, and reimagining leisure as a driver of long-term resilience. Tutor(s)
