The Elijah Mills House is located in southern Windsor, on the west side of Deerfield Road just north of Interstate 291. It is a 2+1⁄2-story brick building, with a side gable roof and two interior brick chimneys. The main facade is five bays wide and symmetrically arranged, with a center entrance. Windows are set in rectangular openings, with stone sills and headers of soldier bricks in a splayed layout. The entrance is framed by narrow boards and topped by a semi-elliptical transom window. A single-story wood frame porch extends along the south side, covered by a low-pitch shed roof. The southern gable end has a bricked-over semi-elliptical opening. A wood-frame ell extends to the rear of the main block, joining it to an old barn. The interior follows a central hall plan, with an archway separating the entry area from the two-run staircase. There are two rooms on either side of the hall, each of the front parlors featuring a decorative fireplace mantel. There are relatively few 20th-century alterations.[2]
The house was built about 1822 by Elijah Mills, whose family operated one of the Windsor brickyards. The house is notable for its use of brick in places many period houses do not normally have it, including for the walls and floors of the cellar area. Similar uses are seen the Oliver W. Mills House, just up the road. The rear ell and barn both exhibit alterations supporting use of their attic spaces as housing for farm workers.[2]
