The Henry Stewart House is a historic house at 294 Linden Street in Waltham, Massachusetts. The 2-1/2 story brick building was built c. 1900-11, and is a rare local example of Jacobethan style. The house was built as the gardener's cottage for Cornelia Otis Warren's Cedar Hill estate. The house has a T-shaped plan, with projecting end gables that project upward in curved Flemish styling. The second level above the main entrance is half-timbered wood construction. The walls have highlighting heavy beltcourses, and the chimneys are topped by corbelled pots.
