Reusing Rooftops, in collaboration with the Mies van der Rohe Foundation, has launched an international competition to transform the rooftops of Barcelona into useful spaces that enhance the quality of life for its citizens.

The competition invites participants from all over the world to propose innovative solutions for the sustainable reuse of these urban spaces and features a jury made up of firms such as Bjarke Ingels Group (BIG), MVRDV, and Porras Guadiana

Additionally, as part of the Barcelona Architecture Weeks 2024 program, there will be an event on the competition’s topic featuring speakers from Bjarke Ingels Group (BIG) and Batlleiroig, followed by a panel discussion with industry and public administration experts. 

The competition prizes total 5,000 euros, distributed as first, second, and third prizes, along with two special mentions, “Soprema” and “Tierra,” each worth 500 euros. Moreover, the proposals most highly valued by the jury will be published in magazines, blogs, architecture websites, and social media.
