Rock Hill Farm
Also known as: VDHR File No. 053-1057
Why it's listed
Rock Hill Farm is a 68.8-acre farm in the rolling northern Virginia piedmont, near Bluemont in Loudoun County. Its main building is a two-story, stucco-covered fieldstone house built in 1797 on a Quaker plan, with a wide hall and two smaller rooms. Additions were made around 1873, 1902, 1947 and 1990, yet the interior keeps nearly all of its original woodwork and door hardware. The hall's paneling and chimneypiece blend Georgian and Federal details. Around the house stand a bank barn, smokehouse, garage, corncrib, dairy and run-in shed from the 1797 and 1873 building phases, along with dry-laid fieldstone fences and the remains of a boxwood garden. A small cemetery from about 1820 holds a marble marker for a fifteen-year-old girl and three fieldstone-marked graves. The farm was listed for its architecture, with a period of significance running from 1797 to about 1950.
Significance in brief: The nomination argues the property is significant under Criterion C for architecture. The 1797 Quaker-plan house retains nearly all of its original woodwork and hardware, showing a transition from Georgian to Federal styles. Later additions and outbuildings document the farm's evolution through about 1950.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
