Missing Middle Housing is a range of multi-unit or clustered housing types—compatible in scale with detached single-family homes—that help meet the growing demand for walkable urban living.

The Types

The Missing Middle Housing types provide diverse housing options, such as duplexes, fourplexes, and bungalow courts, that fit seamlessly into low-rise walkable 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.

“Well-designed ‘Missing Middle’ buildings unify the walkable streetscape as they greatly diversify the choices available for households of dierent age, size, and income. Smaller households tend to eat out more, helping our neighborhood attract wonderful restaurants. Diverse households keep diverse hours meaning we have more people out walking our streets at more varied hours—keeping them safer.”
