Carbery House

423 6th Street, SE

Carbery House was built in 1803 as a two-story dwelling with Flemish brick bond. The three-story tower addition, which dominates the façade, was built in 1889. Other additions include a two-story brick extension off the west end and a one-story front porch. The house was originally built in the Federal style popular from 1790-1820, and was most likely a five-bay house, centered about the front door, with keystone lintels, and nine-over-six double-hung sash windows. Notice the Federal style symmetry of the original front and side elevations and the elegant entrance with semi-circular fanlight, four-light sidelights, and six-paneled wood door.

The three-story tower features an open porch with brick-arched supports on the first floor, and a pyramidal roof with flared eaves, slate tiles, and a circular louvered roof vent. A few feet from the roofline, the Flemish brick bond switches to a row of dogtooth bricks and a large corbelled cornice often seen in late 1800s Capitol Hill Queen Anne style townhouses, suggesting that the roof over the main house was likely raised when the tower was added. The original roof may have resembled the gabled roof with dormer on the house next door at 421 ½ 6th Street. The garage along the alley was constructed between 1924 and 1928.

The house was built by Robert Alexander (1781-1811); he listed it as his address as early as 1804 when he served on the Third City Council. Alexander was an architect and contractor and was instrumental in the 1807 design of nearby Christ Church at 620 G St SE. He worked closely with Benjamin Henry Latrobe, an architect and Surveyor of Public Buildings of the United States, on construction projects at the Navy Yard. Later in 1807, Latrobe designed a Greek Revival Customs House for the Treasury Department in New Orleans and not only helped steer the contract to Alexander, but also rented 423 6th Street from Alexander when he left to oversee the work. The New Orleans project was ill-fated; Alexander succumbed to Yellow Fever in 1811 and the Customs House was outgrown and demolished by 1819.

The house’s namesake is James Carbery (1793-1851). He owned the house from 1833 until his heirs sold it in 1881. Carbery was a naval architect, an Inspector of the Timber at the Navy Yard, an original member of St. Peter’s Church, and a local legislator from 1826-1839. His brother Thomas (1791-1863) was the mayor of Washington from 1822-1824. W. W. (William Weaver) Danenhower (1820-1894) owned the property in the 1880s and oversaw the tower addition. President Lincoln brought Danenhower to Washington, DC to serve in his government. Danenhower went on to develop other real estate including several rowhouses between F & G Streets NE and 2nd and 3rd Streets NE – within the recent boundary expansion of the Capitol Hill Historic District.
