245 Chestnut Street is a two-story stone structure originally with an off-center chimney (now removed) and a three-room German plan. One interesting feature of the house is the heavy board ceiling, which consists of two summer beams supporting 5-inch-thick planks with stone-and-mortar chinking, a Germanic construction tradition called paling.
Dendrochronological analysis has shown that the south summer beam was felled in the spring of 1773, suggesting that the building was constructed at this time or shortly thereafter.
