The Sears, Roebuck and Company Complex is a building complex in the community area of North Lawndale in Chicago, Illinois. The complex hosted most of department-store chain Sears' mail order operations between 1906 and 1993, and it also served as Sears' corporate headquarters until 1973, when the Sears Tower was completed. Of its original 40 acre complex, only three buildings survive and have been adaptively rehabilitated to other uses. The complex was designated a National Historic Landmark in 1978, at which time it still included the 3000000 ft2 mail order plant, the world's largest commercial building when it was completed.[3][1] That building has been demolished, its site taken up by the Homan Square redevelopment project.[4]
These core buildings occupy an area bounded on the north by West Arthington Street, the west by Central Park Avenue, the east by Spaulding Avenue, and the south by West Fillmore Street.
