When Ryan Diggins, a commercial developer in Denver, started contemplating his next project a few years ago, he was keen on using old shipping containers to construct a modern mixed-use microspace on an empty lot in RiNo. Unfortunately, nobody had attempted such a complex in Colorado (How would it work? What would it look like?), so he turned to a classic toy for early prototyping. “I used Legos to mimic stacking and orienting the containers to see what looked best,” he says.
