This is the Gateways Hospital at 1891 Effie Street. According to
gatewayshospital.org, the hospital was opened in 1961 and dedicated by Eleanor Roosevelt. It's Julius Shulman's
"Job 3336: Gateways Hospital (Los Angeles, Calif.), 1961". There are 21 photos in the set, so I've just picked seven to give a flavor of what they show.

The Isaac and Anna Grancell Activities Building can be seen behind the main building on the elevated view above.
This hall, complete with table tennis tables, must be inside the Isaac and Anna Grancell Activities Building.
Another activities room. The man at the end seems to be examining the straightness of an object he has in a vise.
I'll finish the Shulman pictures with this bedroom shot.

Looking at Historic Aerials, it seems that the north-eastern extension was added before 1972. The Isaac and Anna Grancell Activities Building is the one with the dark roof, next to the parking lot on the left.
