Competition overview
Buildner presents Underbridge #2, the 20th competition in its Affordable Housing Series, which invites architects, designers and creative thinkers to explore the untapped potential of spaces beneath bridges.
Found in cities around the world, these overlooked urban areas offer opportunities for innovative housing solutions that respond to growing population density while making use of existing infrastructure.
The competition challenges participants to develop visionary proposals that transform underbridge spaces into vibrant, liveable environments.

Proposals should demonstrate how underutilised infrastructure spaces can be reimagined as functional residential environments that are scalable, sustainable and capable of serving diverse urban communities.
