Mason-Fitz House // 1829

One of six attached houses townhouses between 70-75 Beacon Street, this stately granite-faced residence was built concurrently with its neighbors in 1828 on speculation for the Mount Vernon Proprietors, a group of wealthy Boston businessmen who helped develop Beacon Hill into the posh, architecturally significant neighborhood it is today. The Mount Vernon Proprietors knew how important Beacon Street was as the entry into the neighborhood, and thus, hired Boston’s premier architectAsher Benjamin, to design the row. When completed, all of the houses were identical, but throughout the 19th and 20th centuries, they all deviated from the original design, some gaining additional floors, others adding bay windows, but all together form a cohesive and architecturally significant span of houses. Completed in 1829, the residence at 75 Beacon Street is known as the Mason-Fitz House and was originally owned by Jonathan Mason (1756-1831), a U.S. Congressman and U.S. Senator, and later inherited by his son, William Powell Mason (1791-1867), who engaged in real estate. It was likely William Mason who added the mansard roof in the late 1850s or 1860s, but the main unique detailing of the residence occurred in 1889 when newlyweds, Henrietta G. and Walter Scott Fitz hired the popular architectural firm of Little & Browneto reconfigure the front of the house in the Colonial Revival style. Little & Browne added the rather fanciful, oriel windows on the facade, which include the three, small hipped-roof oriels on the second story and larger projecting oriel on the first floor with fanlight and leaded glass. Cambridge architect, Edward T. P. Graham later purchased the residence and petitioned to convert the single-family house into eight apartments, but was denied, later converting the residence into four units. Today, the Mason-Fitz House is broken up into two larger condominium units. 

Callender-Sedgwick House // 1802

Built in 1802, this large residence at 14 Walnut Street is among the oldest extant mansions on the South Slope of Beacon Hill and includes a large hidden garden behind a granite block retaining wall. John Callender, Clerk of the Supreme Judicial Court of the Commonwealth, purchased land at the corner of Mount Vemon and Walnut streets for $2,000 and immediately started construction on his requested “small house finished for little money $5,000-$7,000”, but this was anything but modest. The house originally had its primary facade facing Mount Vernon Street, but in 1821, Walnut Street was lowered by city officials, so Callender had the granite retaining wall built for the garden and new entry built on Walnut Street. Mr. Callender lived here until his death in 1833 and the property was purchased by members of the Lyman family and later by Harriot Curtis (1881-1974) an early amateur female skier and golfer who used her fortune as a philanthropist, funding medical facilities in Boston for impoverished immigrants and served as dean of women in Hampton Institute in Virginia, an HBCU from 1927-1931. The most significant owner, Ellery Sedgwick (1872-1960), lived here from 1908 until his death in 1960. Sedgwick worked as editor of the Atlantic Monthly (now known as The Atlantic), and under his ownership, the magazine became one of the most circulated magazines in the world. The Callender-Sedgwick House features unique flushboard siding, providing a seamless surface that resembles a masonry wall when painted earth tones and a 19th century oriel window. The brick end elevation is punctuated with bays of hung windows and the recessed entry with a long, granite garden wall which has been well-preserved by owners.
