Sunlight fills every corridor, the exit visible even from the opposite end of the apartment building. Its 60 bedrooms have no doors to shut, but, instead, window-sized wall cutouts to see through to the living room. And the “safe courtyard,” filled with deep-pink rose bushes and shade umbrellas, is open to the sky yet fenced off to prevent outside entry from Federal Boulevard. The design is unique in Colorado and rare nationally, a “trauma-informed” apartment building that soon will house people who for years have lived on Denver’s streets, in and out of jail, detox and emergency rooms.
