[1] The Elijah Mills House is located in southern Windsor, on the west side of Deerfield Road just north of Interstate 291.

Windows are set in rectangular openings, with stone sills and headers of soldier bricks in a splayed layout.

A single-story wood frame porch extends along the south side, covered by a low-pitch shed roof.

The interior follows a central hall plan, with an archway separating the entry area from the two-run staircase.

The rear ell and barn both exhibit alterations supporting use of their attic spaces as housing for farm workers.
