Brian Crombie speaks with Dan Parolek, Founding Principal of Opticos Design, one of the foremost urban designers and architects working to meet the growing demand for walkable urban living.

The Missing Middle Housing types provide diverse housing options, such as duplexes, fourplexes, cottage courts, and multiplexes. These house-scale buildings fit seamlessly into existing residential neighborhoods and support walkability, locally-serving retail, and public transportation options. They provide solutions along a spectrum of affordability to address the mismatch between the available U.S. housing stock and shifting demographics combined with the growing demand for walkability.
