A 90-year-old home in one of Hinsdale's most historic neighborhoods sold for $3.02 million on Oct. 19.

The five-bedroom, four-bathroom house at 635 S. Oak St. went for $726 per square foot, according to Shaw Local. The two-story home, built in 1936, has 4,154 square feet of interior space, a fireplace and two parking spots. The lot measures 0.7 acres.

The property sits in Hinsdale's Robbins Park Historic District, which the Village of Hinsdale has described as "one of our most historic and architecturally significant neighborhoods." The district covers southeast Hinsdale, stretching east to County Line Road, south to Eighth Street, west to Garfield Avenue and north to the railroad tracks.

The home is a Colonial Revival, according to its MLS listing, which described it as designed by Harford Field. The Village's National Register Historic District information packet, published in July 2007, lists 635 S. Oak as a Spencer Solon Beman design. The reason for the discrepancy is unclear.

The MLS listing noted the house had been owned by one family and featured original details including millwork, six-panel doors, floor-to-ceiling push-out windows, old-growth Douglas fir paneling and Indiana limestone. Elaine Pagels of Berkshire Hathaway HomeServices Chicago listed the property.

The sale is one of several seven-figure Hinsdale transactions recorded between August and October. A home at 104 S. Monroe St. sold Oct. 6 for $3.4 million, or $453 per square foot, according to Shaw Local. A new home at 910 Allmen Ave. sold Sept. 18 for $3.1 million, or $481 per square foot.

At $726 per square foot, the Oak Street sale carried a higher price-per-square-foot figure than both of those transactions. A home at 244 E. 1st St. sold Aug. 21 for $6.8 million, or $1,011 per square foot, the highest recent per-square-foot price among reported Hinsdale sales.

For residents tracking development and preservation in the Robbins Park district, the sale raises a question the listing itself flagged: the MLS description noted the property could interest buyers looking to restore the home, expand it or build new construction on the 108-foot-wide parcel.

Deed records for the transaction are available through the DuPage County Recorder of Deeds, and building and demolition permits can be checked through the Village of Hinsdale permit portal.
