The brick house pictured here is owned by the local branch of the Izaak Walton League, a conservation group. The home was built by the Jefferson family in the 1850s by the Jefferson family. The dwelling, which I photographed on Thursday, is on River Road in Des Plaines south of Oakton. Even in winter, when you drive past it's difficult to notice.
The home is now owned by the Forest Preserve District of Cook County.
