Kingwood Center (Additional Documentation)
Why it's listed
Kingwood Center is a 47-acre estate in Mansfield, Ohio, combining a Georgian Revival mansion, formal gardens, and nature trails. Kingwood Hall, designed by C. Mack of Cleveland and finished in 1926, is a symmetrical brick building with a tall hipped roof, brick quoin-like banding, and wings with mansard roofs. Inside are 27 major rooms, mostly with original furnishings, including French furniture and hand-painted wallpaper in the dining room. In 1932 a U-shaped group of brick outbuildings was added, including a poultry house, a stable and a storage building, together with a tower. Greenhouses were replaced in 1960 and a service building was added in 1968. The grounds are known for formal perennial gardens, French and Italian statuary, and trails with over 130 native Ohio species. Builder Charles Kelley King, an Ohio Brass Company engineer who rose to chairman, left the property to the public with an endowment for its perpetual care. It is now managed as a botanic garden and museum by a foundation.
Significance in brief: The nomination calls it an outstanding example of a late Georgian revival mansion that is little altered and keeps its original interior. The grounds are noted for their statuary, landscape planning and formal perennial gardens, and the nature trails hold over 130 native Ohio species. Charles Kelley King left the estate to the public with an endowment for its upkeep.

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).
