Introduction
COMPETITION ORGANISERS
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 #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 choose 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 project should demonstrate the potential to transform a limited footprint into something innovative and impactful.
This edition celebrates the ingenuity needed to balance sustainability, functionality, and 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 is a call to bring fresh perspectives to old spaces, proving that thoughtful adaptation can be a powerful tool for a more sustainable future.

Design assessment
Participants will have the option to request a personalised in-depth design assessment of their project for a fee after the competition results are published.
This feedback highlights the strengths of each submission and identifies areas for refinement, offering participants valuable insights into their work.
The design assessment serves as both a learning tool and a reflection of a project's performance. It helps participants better understand their submission, see how it compares with other entries, and identify opportunities for growth in future projects.
