Among the architectural treasures of Glencoe are two small collections of homes designed by eminent 20th-century architects—and each of those neighborhoods has a derelict house, a victim of the recent housing bust.

Ravine Bluffs is a cluster of six homes designed by Frank Lloyd Wright in the 1910s. The derelict house there now has a savior, a Chicago architect who devised a financial plan that allows him to get the house in livable condition before he buys it.

A quarter-mile away is the Forest Crest subdivision, whose 22 ranch houses by the architects Keck & Keck were built in 1952. One of those houses, stripped of many of the mid-century architects’ characteristic touches, was foreclosed last year, its renovation already at a yearlong standstill. The agent for the house expresses skepticism that anyone will come along to fix it. Click through the slide show below to tour the two houses and learn more about their potential fates.
