Montana State University

Montana State University students are playing an important role in helping the homeless in Bozeman.

MSU architecture students are designing and building prototypes for a new program called Housing First Village, a planned community to be built off campus based on the “Housing First” model. The concept behind the project is that people need stable housing before they can find jobs and otherwise turn their lives around.

Partnering with the Human Resource Development Council and the local faith community, MSU students designed and built the first tiny house prototype for the village over three semesters as part of professor Ralph Johnson’s “Design for the Community” class in the College of Arts and Architecture. Two days before spring commencement, they celebrated its completion by welcoming more than 100 visitors to the 150-square-foot house in MSU’s Family and Graduate Housing.

Royce Smith, dean of the College of Arts and Architecture, said the students are contributing creative solutions to some of our communities’ most pressing problems.

“This particular project touches every facet of assistance and humanity in such a special way,” Smith said. “This work is a crucial part of our land-grant mission — helping students to use their skills to contribute to a better Montana.”

Lawns Are an Ecological Disaster
