Can an App Renovate a Neighborhood?

On a sleepy stretch of West Jefferson Boulevard not far from downtown Los Angeles, cars typically speed past blocks of old warehouses and blank retail facades for destinations elsewhere. But slow down, hit the sidewalk and peek into and around a few buildings, and you’ll see the telltale signs of renovation: sandblasted walls, new windows, work crews and exposed wood beams.

In an expansive brick building that once housed a child-care center before reverting to a warehouse, an inside-out renovation for a future food hall has stripped the wooden ceiling down to gorgeous bow trusses, sunlight filtering through the gaps and lighting up a floor of dirt filled with tracks from heavy machinery.
