Osborn, Benjamin, House
Also known as: Mother Ann Lee House

Why it's listed
Set in a meadow at 1,550 feet in the Berkshire hills, this modest one-story house with a gable roof and central chimney was built around 1759 by Benjamin Osborn on a 93-acre lot. It is the oldest standing structure in Mount Washington and a scarce survivor of the small homesteads that early colonial settlers built in the hill towns. Its three-bay facade and two-room plan, recalling the older hall-and-parlor arrangement, differ from the usual larger center-chimney houses. Osborn was an early settler and one of the town's proprietors. In 1781 his family hosted Shaker followers of Ann Lee at the start of their New England tour, and the house became the focus of a short-lived Shaker outpost. Changes around 1906 and 1950 altered the interior and exterior finishes. A small burying ground nearby, the town's oldest, with stones from 1772, is also included. The state acquired the property between 1958 and 1961 for the state forest.
Significance in brief: It is the oldest standing structure in Mount Washington and a rare surviving example of the small homesteads built by early hill-town settlers. Its two-room plan varies from the usual three-room center-chimney form. The Osborn family also welcomed Shaker evangelists on their first New England tour in 1781, making the house a base for an early Shaker outpost.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
