Backyard homes, John Parkinson

Is the solution to LA's housing crisis in our backyards? DnA visits a Highland Park couple that worked with the city on test-building an ADU, or accessory dwelling unit. Did it pencil out, and can ADUs be a new frontier for design innovation? And do you know the name of the man who built much of downtown Los Angeles? DnA speaks to the director of the first-ever documentary about architect John Parkinson.
