This Italian villa-like house is on the west side of a post-glacial pond, on land that was the former site of the Atteridge farm. Two complimentary gatehouses on the east side of the pond once flanked the original estate entrance off Green Bay Road.

The classical design of the house incorporates hip roofs, deep overhangs and an arched loggia at the entry. Rooms on the ground floor are accessible through a grand central hall; two wings surround an outdoor courtyard. The garden terrace has an open “court porch” below. Off the master bedroom on the second floor is another open terrace.

Olmsted Brothers laid the grounds of the estate. Kate Brewster created garden rooms in the manner of Gertrude Jekyll. These vignettes of seasonal blooms were off the west side of the house. From the back terrace there was a long view out to the Skokie lagoon.

The Brewsters were both patrons of the arts. Walter Brewster collected Whistler prints, now at the Art Institute of Chicago and their gardens displayed the work of Sylvia Shaw Judson, Carl Milles and Alfeo Faggi.
