From 1766 to 1832, Doughoregan Manor was the country home of Charles Carroll of Carrollton, last surviving signer of the Declaration of Independence. He lies buried in the chapel attached to the north end of the mansion. "Doughoregan" was a family estate in Ireland. The Georgian brick plantation house, built by Carroll's father around 1727, was enlarged and remodeled by his grandson in the 1830s in the Greek Revival style. In its current configuration it is a brick, two-storied, U-shaped building. The roof is in gabled sections, some with balustraded decks, and in the center is an octagonal cupola. The front center entrance has a one-story tetrastyle Doric portico and is similar to the rear portico. The chapel and kitchen are attached to the main block by hyphens.
The private chapel was built at a time when the founding of Roman Catholic parish churches was prohibited in the colony. The chapel served as the primary meeting place for the local Catholic community until as late as 1855 when nearby parishes were founded. The chapel continued to be open to the public on Sunday mornings for Mass until the 1990s, when the family discontinued the practice due to overcrowding.
Members of the Carroll family still own and live in the manor, which sits at the center of an 892-acre (3.61 km2; 1.394 sq mi) of the original 1,300-acre (5.3 km2; 2.0 sq mi) estate.  In the late 1990s a family member observed, "Only God, the Indians and the Carrolls have owned this land." The estate and Manor Lane are closed to the public.
In an attempt to keep the majority of the property in the hands of the Carroll family for future generations, the owners of the estate struck a deal in 2008 with Erickson Retirement Communities to sell 150 acres (0.61 km2; 0.23 sq mi) with the option to sell an additional 38 acres (0.15 km2; 0.059 sq mi) in the future, but in June 2009 it was announced that the entire deal had fallen through, leaving the Carrolls back where they started, in a precarious financial situation. According to Camilla Carroll, co-owner of the estate, "There is no money now to restore anything, and historic buildings are falling down as we speak."
In addition, 36 acres (0.15 km2; 0.056 sq mi) may be donated to the county for parkland in order for the Carrolls to take advantage of the county's agricultural preservation program, which would protect 500 acres (2.0 km2) of their estate.
On July 23, 2010, members of the Howard County Council, sitting as the zoning board, unanimously approved a plan to rezone 200 acres (81 ha) of Doughoregan Manor. The zoning change will allow more than 300 single-family homes to be built on the east side of the property. Earlier in the year the council approved an extension of the public water and sewer system to the development. On October 8, 2010, a man who lives on the eastern edge of Doughoregan filed a petition in circuit court for judicial review of the zoning decision.
The house was originally a 1½ story brick house with a gambrel roof. A detached brick chapel stood to the north, while a brick kitchen stood to the south. The dependent buildings were incorporated into the main structure in the 1830s by Charles Carroll V, raising the main house's roof to make a two-story structure. The new roof was topped by a balustraded deck with an octagonal cupola. The front (east) facade gained a one-story portico with doric columns. A similar portico to the road was built with a room above, while a marble-floored veranda with iron columns extended to each side. The chapel's roof was raised and it was joined to the main house by a two story passage, as was the kitchen. The work resulted in a Palladian style five-part house extending almost 300 feet (91 m).
The house's interior has a center hall plan, with the paneled main hall extending the full depth of the house. Stairs are located in a small side hall on the north side. A library, large parlor, small parlor and dining room occupy the first floor, with bedrooms on the second.
