The Gambrel-roofed cape-style house at 29 Joshuatown Road at Hamburg Bridge in Lyme is architecturally distinguished. It is the only surviving example in the state of a distinctive type of chimney vaulting: an arched passage through a split chimney, with an elaborate doorway surround at the back of the passage. The house was built c. 1790-1803 by Captain William Johnson. He was a mason and the second floor has a large arch-ceilinged room that was used as a Masonic Hall. Captain Johnson died in 1818 and widow Mitty soon sold the house, although she returned to Hamburg Bridge in 1848 and bought another house on Joshuatown Road.
