Much larger than one room, probably a Consolidated School.  From US218, turn west on 130th St and proceed to 160th Ave/W55 and then turn south to 140th St, and then turn west. Go 1/2 mile to 155th Ave and turn south to Mt. Hamill.  First street on right/west is 142nd St; turn there and go one block to the school, which sits on 154th Ave just south of of 142nd.

This first shot is the south side of the school.
