Re:Form - New Life for Old Spaces / Edition #3 advance registration deadline is approaching!

Choose a site—used, abandoned, or forgotten—anywhere in the world, and give it a new purpose.

In a world facing urgent environmental and spatial challenges, the most sustainable solutions may come not from new construction, but from reimagining what already exists. Re:Form Edition #3 invites architects, designers, and innovators to embrace the challenge of adaptive reuse, working within spaces under 250 square meters to give them renewed purpose and relevance.

Participants are free to select any existing structure—whether currently in use, abandoned, or neglected—anywhere in the world. From unused storefronts and aging sheds to underutilized garages or portions of larger buildings, each proposal should demonstrate how a limited footprint can be transformed into something innovative and impactful.

This competition celebrates the ingenuity required to balance sustainability, functionality, and thoughtful design within an existing space. How can we rethink these structures to serve new purposes, meet contemporary needs, and positively impact their communities? Re:Form Edition #3 is an invitation to bring fresh perspectives to old spaces and show that careful adaptation can play a powerful role in shaping a more sustainable future.
