Like most old Bucks County farmhouses (the oldest part of the house dates to 1730), this one has been expanded over the years. Curl up by the Mercer-tile fireplace in the library, pay a visit to the Thoroughbreds that gallop nearby (there are even facilities to board your horse), or gaze at the creek and pond from the glass-walled dining room. Guest rooms are named for presidents. In the George Washington Suite, the master bedroom has stone walls and a beam ceiling. The second bedroom, which is great for children, has a bed tucked in an alcove, which is painted to look like a four-poster bed.
