Next generation urban housing

Urban housing for the 75%+ of the country's households that aren't married with kids is evolving:

10' exposed ceilings replace 8' hung ceilings. More light. More air. Who cares if you can see the ductwork? It's more authentic.
Large windows replace small windows. More light. More air. Great view. Technological advances help windows insulate better despite more glass.
Open floor plan replaces compartmentalized rooms. Larger sense of space. More social. More flexible.
Walkability replaces isolation. Workplace/transit, groceries, shopping and entertainment are 5-10 minutes away.
