The Asa Locke House is set on the south side of High Street, at the southeast corner with Overlook Way, in what is now a predominantly residential suburban area. It is a -story wood-frame structure, three bays wide, with a front-facing gable roof and clapboard siding. A single-story porch extends across the north-facing front and around to the east side, supported by chamfered square posts with segmented-arch bracketing. The front door is set to one side, with full-length windows in the side base. The door is flanked by sidelight windows, and is topped by a transom window. A gabled two-story bay projects from the east side, with a lunette window in the gable, and a two-story ell and garage extend to the rear.
