The Sweetser House is located at the northeast corner of Franklin Street and Dale Court, a short way east of the center of Stoneham. Franklin Street is a major east–west through street connecting Stoneham to neighboring Melrose. The house is a 2-1/2 story wood frame structure, with a front-facing gable roof and a modern concrete foundation. Most of the house is sheathed in clapboard siding, but the front is entirely finished in flushboarding, as is part of the right side. The corners of the building are pilastered, with an entablature that encircles the building. The front facade, facing south, has a single-story hip-roof porch extending across its width and around to the right, supported by Doric columns. The facade is four bays wide, with full-length windows on the ground floor and smaller sash windows above. There are two sash windows in the fully pedimented gable end. The porch on the right side ends in a projecting section that houses the main entrance and a stairwell. Each side of the roof has a single gable-roofed dormer. The interior of the house consists of a mix of Greek Revival elements overlaid by Victorian and Colonial Revival alterations, most of which date to the buildings conversion to a duplex in the 1890s. Room dividers with leaded glass and wooden spindled screens were added to the downstairs rooms, and similarly styled elements were overlaid on some windows. A complex bookcase system was added to separate the two public parlors. The house originally stood at 434 Main Street, a short way south of Stoneham's Central Square. It was built on that site in 1842 by Warren Sweetser, a prominent figure in the town's economic life in the 19th century. Sweetser owned a local dry goods retail store, and served for many years as the town postmaster. He was also involved in a small scale in the town's cottage shoemaking industry, which dominated its economy. Because Stoneham's economy grew slowly during the time the Greek Revival was in vogue, this house is one of its few high-style houses in that style. After Warren Sweetser died in 1890, his heirs converted his house to a duplex, adding the entrance tower to the right, the dormers on the roof, and a modern service ell to the rear. The house was sold out of the Sweetser family in 1929, and was eventually converted to commercial use, given its proximity to Central Square. In 1999 it was purchased by a developer, who announced plans to raze the building and redevelop the site. The town located a preservationist will to buy and move the structure, which was moved to a temporary location later that year. It was moved to its present location in 2000, although the lot is too small to accommodate the 1890s service ell, which was demolished.
