Commonwealth Avenue in Boston’s Back Bay neighborhood is a dream, no matter what time of year, though I am a huge fan of it in the winter so the leaves don’t obscure the architectural details! This home just steps from the Public Garden was built in 1903 for Walter Baylies (1862-1936) and his wife, Charlotte. The couple had purchased a c.1860 Second Empire mansion (basically a sister house or twin to the adjacent at 3 Commonwealth Ave), and demolished it for a more “modern” residence. Baylies was extremely wealthy with investments in nearly everything, and he wanted his city residence to stand out amongst the earlier, brick and brownstone townhouses on the eastern edge of the neighborhood. Architect Arthur Rice designed the house in the Renaissance Revival style, and it is finished with Indiana Limestone. Of particular note is the one-story ballroom, which was built to the side of the home, set back behind a small garden. An empty house lot, formerly occupied by a stable, was used simply for the Baylies’ ballroom, constructed in 1909 for their daughter. Talk about a status symbol! The home was purchased by Walter’s heirs in 1941 by the Boston Center for Adult Education. The home was again purchased in 2020, and is back to a single-family home! I can’t even imagine how stunning the interior is!
