"We just finished a casita build with Jon and Amanda at Unstoppable, and the experience couldn’t have been better. After interviewing contractors for over six months, we knew within minutes that they were the right fit—honest, knowledgeable, and completely transparent.
They clearly laid out our options for building on our existing structure versus starting fresh, and guided us through selecting finishes in a way that never felt overwhelming. Amanda kept every phase organized and on schedule, while Jon managed the build with meticulous attention and consistent communication.
When unexpected issues came up—like discovering our old AC unit wouldn’t work for the new space—they handled everything quickly and thoughtfully, walking us through solutions, costs, benefits, and even managing the paperwork.
Throughout the process, Jon and Amanda truly lived up to the name Unstoppable. Their momentum, communication, and commitment to quality never wavered, and the project wrapped in about three months.
Now that we’ve been in the space for a few weeks, we’re even more certain we made the right choice. The casita is beautiful, functional, and a joy to be in—thanks entirely to the unstoppable team that built it!"

Client feedback
"If you're looking to build an ADU in Tucson, I can't recommend Unstoppable Construction more. Amanda and Jon went above and beyond my already high expectations and built this place quickly and expertly. We were able to stay within our budget and desired timeframe, which isn't always the case for such a monumental project."

Client feedback
"Much thanks to Amanda and Jon for helping us realize a
backyard art studio/casita for all of our projects waiting in
the wings! We greatly appreciate A&J’s approach to
supporting small-space living ideas at reasonable prices –
and prioritizing our bottom line rather than their own.
Worth every penny!!"
