It is operated by the Braintree Historical Society as the Thayer House Museum, which is open year-round.

[1] The Braintree Historical Society constructed a reproduction post-and-beam dairy barn to complement the Thayer House Museum in that same year.

A cannon that was a gift from the United States Military Academy at West Point, is on the front lawn of the House.

Both wheels were reconstructed by a wheelwright and a blacksmith, one for the wood and one for the iron tires, working together in Colonial Williamsburg, using only tools and techniques consistent with the period.

The wheels were reinstalled and the cannon was rededicated in a formal commemoration ceremony on the front lawn of the Thayer House with the Williamsburg craftsmen present, on June 21, 2015.
