From Better! Cities & Towns writer Dan Parolek: "The mismatch between current US housing stock and shifting demographics, combined with the growing demand for walkable urban living, has been poignantly defined by recent research and publications by the likes of Christopher Nelson and Chris Leinberger and most recently by the Urban Land Institute’s publication, What’s Next: Real Estate in the New Economy. "Unfortunately, the solution is not as simple as adding more multi-family housing stock using the dated models/types of housing that we have been building. Rather, we need a complete paradigm shift in the way that we design, locate, regulate, and develop homes. Missing Middle housing types are a critical part of the solution and should be a part of every architect’s, planner’s, real estate agent’s, and developer’s arsenal.
"Well-designed, simple Missing Middle housing types achieve medium-density yields and provide high-quality, marketable options between the scales of single-family homes and mid-rise flats for walkable urban living. They are classified as 'missing' because very few of these housing types have been built since the early 1940’s due to regulatory constraints, the shift to auto-dependent patterns of development, and the incentivization of single-family home ownership.
"The following are defining characteristics of Missing Middle housing: walkable context, medium density but lower perceived density, small footprint, smaller but well-designed units, off-street parking not driving the site plan, simple construction, community, and marketability." Full article here.
