Built at the turn of the 17th-century, it is one of the community's oldest surviving buildings, and is noted for its association with a prominent early Episcopal minister.

The rear roof face extends to the first floor, giving the house a classic New England saltbox profile.

The front facade is five bays wide, with sash windows arranged symmetrically around the center entrance.

Mansfield had been raised a Congregationalist, but converted to the Church of England, and established a mission in Derby (which Ansonia was then still part of).

Mansfield had to flee during the American Revolutionary War due to his Loyalist leanings, but returned and continued to serve in the local Episcopal church until his death in 1820.
