New neighborhoods spring up in old locations
	The housing industry is rethinking the types of homes they want to build and where to build them. 
	In cities, old industrial buildings and deserted warehouses are being torn down to make way for new housing.
	Young Millennials and older Baby Boomers are rejecting traditional suburban homes in favor of urban living. 

These two generations make up almost half of the American population, 
	Many plan to live near city centers so they can walk to work, shops and restaurants or take public transportation. They prefer smaller homes because they're single or have no kids. They don't want to spend much free time maintaining their homes, and they don't want to spend a lot on gasoline.
	Many 30-something professionals also plan to live in city neighborhoods rather than in the suburbs. And they don't plan to live in multi-story condos, according to Smart Growth America's LOCUS, a coalition of real estate developers and investors who are in favor of urban projects.
	This is a dramatic shift in the types of homes people want, and it's probably not temporary, experts say.
