The Col. John Osgood House is a historic late First Period house in North Andover, Massachusetts. The original part of the house, its left side, was built c. 1720. A second, similar building (without chimney) was then attached to the right side of the chimney at a later date, demonstrating an unusual method of joining the two structures. The house was listed on the National Register of Historic Places in 1990. Read more on Wikipedia
