IncDev Community Spotlight: Joe Silins
“The more training you can get and the more people you talk to, the better.”
Joe Silins is a small-scale developer based in Tucson, Arizona. Joe has a passion for environmental conservation. His career started in planning, then switched to part-time work at a local non-profit that connected people with the environment and part-time residential contracting.
With an interest in natural construction techniques, Joe decided to try out his first project: building a strawbale casita (i.e. accessory dwelling unit (ADU)) as a guesthouse in his backyard.
Modern strawbale construction began when mechanical balers made it possible to compress straw into standardized bales. The technique was common in the Great Plains in the early 1900s and has recently seen a resurgence in the Southwest—likely due to its suitability to the hot, dry climate.

The structure is well-adapted to naturally regulate the internal temperature during the Sonoran Desert’s heatwaves and cold snaps. Because of how densely it’s packed, strawbale is about three times as effective as conventional insulation. (It also offers an increased fire resistance and natural soundproofing.) The casita’s earthen floor—made from soil mixed with sand and straw and sealed with oil—helps to keep it naturally cool. And, for the hottest days of the year, Joe installed a ductless mini-split.
During construction, Joe hosted a few weekend workshops in which community volunteers learned the technique, then assisted him with putting up the walls and applying clay plaster over the bales.
After finishing the guesthouse, Joe started his own contracting company, specializing in alternative building techniques.

This year, Joe attended IncDev’s Northwest Arkansas Field Trip and Small Scale Developer Bootcamp, and said that it “opened my mind to developing more ambitious projects that push the limits of zoning codes and design concepts.” It was really helpful, Joe says, to meet other developers and learn about their projects, as well as diving in to building programs and how to develop pro formas: “I was really impressed by the originality, depth and quality of the presentations and projects from my classmates, and it inspired me to think bigger in terms of the development program for my own project.”
A few projects from the Northwest Arkansas tour, like the stealth fourplexes in Fayetteville and the Haney Houses, have inspired Joe to consider adapting some of the ideas to Tucson.
Recent statewide zoning reforms in Arizona have opened up new incremental development opportunities: The recently-enacted state HB 2721 calls for cities to allow for “middle housing,” like triplexes, quadplexes, and townhomes, near commercial business districts (i.e. Main Street, making room for small-scale projects.
With this in mind, Joe has a concept for a cottage court that takes advantage of the new capacity, building on both his experience with homebuilding, the knowledge gained from IncDev’s Bootcamp and the Northwest Arkansas tour, and his new network of other small-scale developers.
He credits IncDev with helping to really motivate this upcoming project. “Seeing other small developers bringing their visions to fruition really helped me see how I could do the same with mine.”
