The “double-house” that Captain William Latham built with Dr. Thomas Kendrick in 1817 showcases Thetford's relative stylistic sophistication during the Federal period. The building is two side-hall houses that share a center wall, each with a setback one-story wing and one-story rear ell. The house reads as a single imposing dwelling with symmetrical dependencies, not unlike some of the fine Federal houses in neighboring Orford, New Hampshire. It was considered the most elegant house in the small linear village of Thetford Hill and may have been built by local carpenter Thomas Turner. The two entrances with half sidelights and pilasters capped by broad-arched carved fans show a relationship to Federal-style craftsmanship in Norwich, Orford, and Bradford. Kendrick married Latham's sister, and the two men were partners in Latham's store in the village, so the imposing house (formally divided by deed in 1821) reflected both their personal and professional lives. Latham donated the funds and materials to build Thetford Academy in 1819, a school attended by his seventeen children. In 1975 his many descendants established the nearby Latham Memorial Library.
