From June 15 to June 20, 2027, the Festival des Architectures Vives (FAV) will take place in the courtyards of private mansions in Montpellier, France, for its 21st edition, themed "Shared Happiness." The festival will continue with events until December 7, 2026, spanning nearly a year. This edition coincides with the 50th anniversary of the 1977 French architecture law, which recognized architecture as an expression of culture and emphasized that the quality of the living environment is a matter of public interest. The FAV has long aimed to make architecture a dynamic, living space where people can experiment, experience, and share ideas. Each year, the festival transforms the historic courtyards of Montpellier’s private mansions into experimental sites where architectural heritage meets contemporary creativity. This year, ten teams will be selected to transform these spaces through their projects, which must reflect the theme of "Shared Happiness." The festival encourages collaboration and innovation, offering a platform for emerging professionals to showcase their visions for the future of living environments. The call for applications is open to young professionals in architecture, landscape design, urban planning, and related fields. Whether applicants are architects, landscape architects, urban planners, or professionals in associated disciplines, they are invited to imagine a project, assemble a team, and submit their interpretation of "Shared Happiness." The deadline for submissions is December 7, 2026. Those interested in participating can find more information and access the application form at the festival's official website: https://festivaldesarchitecturesvives.com/appel-a-candidatures/. The event continues to attract international attention, highlighting the role of architecture in shaping community and well-being.
