Building more sustainable communities, one day at a time.

Build Day is a national initiative created by Engineers for a Sustainable World (ESW). We work to build more sustainable neighborhoods through one-day builds. We bring together students, community members, and local organizations to literally pick up hammers and build a solution to improve community sustainability. Build Day focuses on pressing local issues such as stable food production, clean and equal water access, and urban rehabilitation.

Past Build Days
