[1] The Smith–Mason Farm is located in a rural setting in western Harrisville, just northwest of the junction of Meadow and Old Roxbury roads.

The farmstead is a rambling 1+1⁄2-story frame structure, with multiple sections and additions.

The main house is a 1+1⁄2-story Greek Revival structure, and it is attached to a shed and barn, making a traditional New England house-to-barn complex.

A second detached barn stands across Old Roxbury Road, and a modest cottage is located near the main complex.

It was converted into a summer residence in 1904 by Sara Coe of New York City, who added porches and roof dormers to the house, and dubbed the property "Brookside".
