Modern feeling was uncovered and thoroughly deepened through the "second floor addition on acid" in this original 1950s Morton Grove ranch home, which got buried under layers of former remodeling jobs. If the 20-foot x 20-foot glass wall, interior balconies, exposed spiral heating ducts, and suspended colored cube forms aren't modern enough, how about the first-floor living area, which does not have a single partition, but instead features an intricate steel spider web-like hanging staircase in mid-air? The informal, playful attitude is enhanced by toy-like color selections and by allowing viewers to see the actual exposed, carefully staged structural elements of the house.
