[1] The Jonathan Warner House is located in a rural-suburban area of eastern Chester, at the northeast corner of East King's Highway and Middlesex Turnpike (Connecticut Route 154).

It is a two-story wood-frame structure, five bays wide, with a side-gable roof, two interior chimneys, and clapboarded exterior.

The central bay of the front is framed by two-story Ionic pillars supporting a small flat projecting roof.

The interior of the house has many instance of fine woodwork, including several original fireplace mantels, and the main staircase.

Warner was a wealthy farmer, who also operated the nearby Chester–Hadlyme ferry and invested in merchant shipping ventures.
