As in so many rural hotels, the core of the inn is a late-eighteenth-century house that was rebuilt c. 1811 and to which was added a larger hotel wing on the west with a handsome porch similar to mid-nineteenth-century seashore hotels of Cape May. The later wing is known to be the work of otherwise unknown architect Hugh Walters, who was probably also the designer of the c. 1840 stone bathhouse enclosing the sulfur spring.
