[1] The William Bryant Octagon House stands east of Stoneham's Central Square, at the northwest corner of Spring and Washington Streets.

It is a two-story eight-sided structure, covered by a low-pitch hip roof with a central octagonal cupola.

The entry, set in the south-facing front facade, is sheltered by an open porch with decorative square posts and brackets, and there is a two-story addition projecting from the rear side of the house.

The other faces of the build have sash windows set in simple molded frames on each floor.

[2] The house was built in 1850 by the Worcester Bros. firm for William Bryant, Jr., a shoecutter, and Lucinda A.
