Ilôt d’Eau is a participatory design project, consisting of a series of workshops organized by Latitude Platform in collaboration with the Faculty of Architecture La Cambre Horta of the Université Libre de Bruxelles (BE), the Cosmopolis Centre for Urban Research of the Vrije Universiteit Brussel (BE), the non-profit organization EGEB, and other partners of the project Des Nouveaux Chemins de l’Eau Solidaires pour le quartier de l’Abbaye. The initiative is part of a wider participatory project presented in the frame of the Contrat de Quartier Abbaye (Forest). Flooding events have been a problem in Forest for a long time, and inhabitants have been looking for bottom-up ways to contrast water-related hazards. The co-design focuses on the opportunity to find room for water within the private realm of the building block. During four different co-design workshops (Ateliers), students and tutors have worked in close contact with the inhabitants, in order to discuss ideas, constraints and opportunities for a sensitive every-day water management. The bottom-up water management projects born from the first atelier have now been realized and will serve as pilot projects for the rest of the initiatives.
