Built about 1810, it was said to be the finest house in town at the time of its completion, and it remains a high quality example of Federal period architecture.

The main facade is symmetrical, with sash windows set in rectangular openings featuring stone sills and lintels.

The main entrance is elaborate, with sidelights and an elliptical fanlight window, all sheltered by a portico with slender Ionic columns and turned balustrade.

The interior has woodwork, paneling and wallpapering that appear to be original, although there have also been murals drawn on some of its walls by Barry Faulkner.

Wyman, a Keene native, was said to have made his fortune at sea, and owned a store in the town center.
