The architect is unknown.","why_significant":"The nomination calls it an outstanding, well-restored example of an early 18th-century First Period saltbox with an integral lean-to roof and plan. Its frame is quirk-beaded and exposed throughout. It is said to have the only room in Andover sheathed on all four walls.","narrative":"This farmhouse at 62 Osgood Street in Andover is a five-bay, central-chimney house with a center entrance and an integral rear lean-to that gives it the classic saltbox profile. It was built between 1699, when Thomas Blanchard acquired the land, and 1740, when his son Josiah inherited the farm. Blanchard was a cordwainer, and a grandson who was also a shoemaker built a shop nearby. The frame is quirk-beaded and exposed, with summer beams in the main first-floor rooms and tie beams above. Both large fireplaces have been restored, and one has a beehive oven. Feather-edged sheathing suggests a date around 1730, and the house is said to have the only room in Andover sheathed on all four walls. It was restored in the 1980s, with a modern rear ell added. The house survives on a remnant of its farmland, now surrounded by newer houses, and is valued as an excellent example of early 18th-century construction.","period_of_significance":"ca. 1699-1740","architect_builder":null,"architectural_style":"First Period","criteria":["C"],"status_note":"Present use is residence; condition is good; restored in the 1980s.
