It wasn’t too long ago that housing developers only built housing, retail developers only built retail, office developers only office. Then the three began joint venturing to build them closer together, what was generally regarded as new urbanism/smart growth.
At last, real estate has evolved to where one developer not only constructs all three uses, but together in one building, and a complex of them at that. What’s also significant is that it’s no longer reserved for avant garde real estate developers like Baltimore’s Struever Brothers Eccles & Rouse, but many others that used to focus on sprawl-inducing projects, although they’re still luxury and chain-dependent. I guess that’s the next phase.
