William McCormick Blair Estate

The William McCormick Blair Estate is a historic estate at 982 Sheridan Road in Lake Bluff, Illinois. The estate was built in 1926-28 for financier William McCormick Blair, who was one of the many wealthy and prominent Chicagoans to build an estate in Lake Bluff in the early twentieth century. Architect David Adler, a well-regarded designer of country houses, designed the estate's main house in the Colonial Revival style. The house has a complex, sprawling shape unified by the consistent use of double-hung windows and wood roofing shingles. The estate also includes a garage, a tennis house, two cottages, two sheds, a folly shaped like a Greek temple, a greenhouse, and a garden.

The estate was added to the National Register of Historic Places on January 31, 2008.
