Dorsey's Search is a parcel of land patented by John Dorsey of Hockley-in-the-hole (1645–1714) in Baltimore County (now Howard County). The 479-acre (194 ha) property adjacent to the north branch of the Patuxent river was surveyed by Richard Beard in December 1684, and granted to Dorsey in March 1696. The property lying between "Long Reach" and "Elk Ridge" was resurveyed in March 1723 to include 750 acres (300 ha). After several generations of inheritance, a series of legal disputes were held over the land by Rezin Hammond and Richard Ridgley in 1820. In 1827 the property exchanged hands to Robert Oliver, builder of Oakland Mill, who combined it with multiple properties totaling 2,300 acres (930 ha). George Gaither acquired the property in 1838. John Dorsey's grandson, "Patuxent" John Dorsey of "Dorsey's Search" built Dorsey Hall at the site.

Dorsey Hall is a historic home in Columbia, Maryland, United States. It is a six-by-one-bay, 2+1⁄2-story stucco structure with a gable roof covered with asphalt shingles. It is a well-preserved and detailed example of the vernacular dwellings of the early 19th century in Howard County and associated with the Dorsey family, one of the "first families" of the county.Dorsey Hall was built on Dorsey's Search, a parcel of land patented by Hon. John Dorsey of Hockley-in-the-hole (1645–1714) in Baltimore County (now Howard County), the brother of Edward Dorsey. The 479-acre (194 ha) property adjacent to the north branch of the Patuxent River was surveyed by Richard Beard in December 1684, and granted to Dorsey in March 1696. The surrounding residential neighborhood of Dorsey's Search was named after the original land grant. Judge Richard Ridgley owned the property which returned to the Dorsey family after his death and purchase by Caleb Dorsey. The farm operated with slave labor until the death of Caleb Dorsey in 1864. In 1963, owner Julius Mandel and Gudelsky Company attempted to rezone the site for high-rise apartments. The property was retitled to the Gudelsky-owned Contee Sand and Gravel Company. The 685-acre property was then purchased by The Rouse Company's shell corporation Columbia Industrial Development Corp. for redevelopment, which was halted in 1968 by residential opposition. The building underwent a renovation in 1979. The stone gristmill remains were still visible onsite at the time.The 5.4 acres (2.2 ha) of land surrounding Dorsey Hall that was acquired by The Rouse Company was resold to land developers Richard Talkin and Donald Reuwer for $785,000 in 2000. In July 2000, a $3.5 million, 32,000 square-foot office project broke ground. By 2001, the site of the estate was subdivided and reduced to 2 acres with a survey claiming no outbuildings were present unlike the neighboring Woodlawn Estate from the same period.Dorsey Hall now stands at the entrance to a business park (comprising mostly medical offices) at 5100 Dorsey Hall Drive, the architecture of which is compatible with the building. However, although it forms an imposing image, it has no signage or other identification and is not open to the public. The confusion is amplified by the adjacent business park at 5010 Dorsey Hall Drive, which bears a sign naming itself the "Dorsey Hall Business Park." Just north of Maryland Route 108, Dorsey Hall is technically at the southern edge of unincorporated Ellicott City, Maryland, rather than the northern edge of Columbia. It was listed on the National Register of Historic Places in 2001.

It was part of a 200-acre farm divided from larger parcels patented by the Dorsey family. The design reflects the transition between the Greek Revival and Italianate architecture styles. The home is associated with Henry Howard Owings, a prominent Howard County landowner and farmer, who also served as a judge of the Orphan's Court for Howard County. Owings purchased the property in 1858 and died at Woodlawn in 1869. The former tobacco farm produced corn, oats, hay, and pork. The majority of the property surrounding Woodland and its slave quarters were subdivided by 1966 and purchased by Howard Research and Development for the planned community development Columbia, Maryland, leaving only 5 acres surrounded by multiple lots intended for development of an Oakland Ridge industrial center and equestrian center. The summer kitchen, smokehouse, corn crib and stable built about 1830 have been replaced by a parking lot.In 2003, Preservation Howard County appealed to the Columbia Association to restore the adjacent stone slave quarters building predating the 1789 Woodlawn house. In 2004 the property surrounding the Woodlawn manor was rezoned from residential to dense office use. All of the 200-year-old trees surrounding the property were declared diseased by the developer-owner and cut down. In June 2006, Developer Ron Brasher submitted plans to build a 71,705sf office building adjacent to Woodlawn with a parking lot surrounding the building on all sides. The project was temporarily delayed due to lack of road access and requests for reduced setbacks. The planning and zoning director cited the developer's efforts to restore and lease the 5000sf mansion for office space or a "condo opportunity" as a way to preserve the manor recently rezoned by the department. In August 2007, the Columbia Association purchased the slave quarters property and approved another $125,000 (~$170,816 in 2022) for restoration with the construction of the office project pending.It was listed on the National Register of Historic Places in 1983.
