Working hard since 2009.

 

Las Rocas

Choachi, Colombia.

Partnering with Los Tecnicos, 4 Walls helped build the first homes using trash in Colombia. The project included the two largest tire domes on the planet, and we continue to prove what is possible when building with waste. 

LAS HORMIGUITAS

Rancho Las Flores, Tijuana, Mexico.

Working with a group of local women, we repurposed over 500 tires and 2,000 plastic bottles into an office space for Baja California's preeminent native plant nursery. 

BORDER GATEWAY TO NATURE PHASE I

Border Field State Park, San Diego, CA.

Using our robust community feedback process, we united local residents, private land owners, government agencies and nonprofits in the design, resourcing and construction of their own state park using trash from the Tijuana River.

CASA DE BOTELLAS

Los Laureles, Mexico

Using over 2,000 plastic bottles stuffed with plastics and foam and 750 glass bottles to retrofit this house, we created a beautiful, well lit, and comfortable artisan work space.  Women here are still repurposing post-consumer waste into art, as seen here.

4walls + Earthship biotecture - Baja Build

Baja California Sur, Mexico

Teaming up with Michael Reynolds and the radical builders at Earthship Biotecture, the 4walls crew help build a fully functioning bio home in Baja California Sur, Mexico.  

Los sauces

Las Playas de Tijuana, Tijuana, Mexico. 

Partnering with the USEPA and SEMARNAT's Border 2020 program, we repurposed over 2,000 plastic bottles stuffed with plastics and foam from arroyo neighborhoods into beautiful mosaic benches during the renovation of this park.
