In Tucson’s western foothills, 28 households have spent 28 years building something that most neighborhoods have lost — a place where knowing your neighbors isn’t incidental, it’s the whole point.

The Milagro Cohousing community is a place where kids can roam freely because the cars park at the edge, and the paths between homes belong to people. Its inhabitants benefit from this simple yet effective design that (once in the community) revolves around people, not cars.

The design started not with the homes, but with the water. In a desert, that makes sense. Dozens of earthen basins and rain gardens are scattered across the site so the water soaks into the earth where it falls, within 20 minutes of a storm. And all water from toilets, sinks, and showers is treated on-site through a constructed wetland, and then pumped back up to irrigate the landscape.

The community sits on 43 acres, but only 8 are occupied by houses. The rest is open Sonoran Desert, permanently preserved (centuries-old Saguaro cactus and all) and accessible to all. Five mountain ranges are visible on the horizon.

The homes are built from thick, locally-sourced adobe blocks — walls that hold the cool and resist the heat. Heating and cooling costs run about 75% lower than those of a typical Tucson home.

But the reason people stay isn’t the engineering. It’s the meals in the common house, the borrowed tools, the neighbors who show up. The kind of neighborhood that used to be ordinary — before we built our lives around cars and the assumption that self-sufficiency means doing it all alone.
