What Our Clients Say About Us

“We could not have found anyone locally with Caddis’s vision and understanding of cohousing. I have found that the nuances of this ‘project’ go much deeper than building design.”

Chris Corby, Germantown Commons Cohousing, Nashville, TN

“Caddis is client-driven and understands budget constraints. At the same time, they are willing to advocate for design elements that they believe are critical to the design solution and to find ways of making them happen without compromising the budget.”

Laura Sheinbaum, Boulder Housing Partners, Boulder, CO

“Caddis has proven to be a team of people who invest in us as we invest in them, a synergy that we have grown to value and appreciate.”

Todd Kilburn, Naropa University, Boulder, CO

“The architectural designs that Caddis develops are consistently cutting edge in terms of site sustainability, energy use, and community design concept while carefully respecting the community and neighborhood context for each individual project.”

Michael Barille, PlanWorks Design, Park City, UT
