HaGIP, or Habitat Groupé Intergénérationnel et Participatif, is a group-housing project in Liège, Belgium, designed around shared living, intergenerational diversity and resident participation.111 Its origins lie in a citizen-led collective formed in 2014 by people seeking a more supportive way of living.211 The project has been occupied since 2022, when residents moved into the completed development.111
Today, approximately 30 children, adults and retired people share the site in Liège, distributed across 13 homes.12 Earlier project documents describe a scheme of 14 apartments, while the current group’s project information reports 13 occupied dwellings.411 The homes are privately owned or rented, and the group is currently complete.311
The development was initiated and carried forward by the HaGIP citizen collective, with the foundation Les Arcades du Laveu acting as the owner of the land and several communal facilities.289 The residential buildings are organised through the co-ownership structure La Briqueterie, while HaGIP brings together the residents and manages collective life.38 The architectural project is attributed to Pierre Hebbelinck for the design and Luc Nelles for its implementation.911
Shared facilities include a garden, bicycle premises and a multipurpose room.812 Residents collectively organise maintenance, meetings, working groups and social events, with decisions taken through a participatory governance system influenced by sociocracy.67 The multipurpose room is also intended to host activities open to the surrounding neighbourhood, including conferences, exhibitions, shared meals and community events.1
The project’s legal structure separates land ownership from ownership of the apartments, using a foundation and co-ownership arrangement intended to protect communal spaces and limit property speculation.8
