DC PRESERVATION LEAGUE Most Endangered Places for 2011 Nomination Form Site Name: Holt/Johnson House Location or Address: National Zoological Park off of Adams Mill Road Year Built: ~1810-1814 Owner Name and Address: National Zoo/Smithsoian, Washington, DC Specify occupant if different from owner: Is the property occupied or vacant? Vacant Historic Designation: ❏ National Historic Landmark X National Register X DC Inventory of Historic Sites ❏ Not Designated or Don’t know Submitter’s name, address and telephone number: Larry Atkins, DC Historic Designs, LLC 3297 C Sutton Place, Washington, DC 20016 Phone: 4434527776 Email: [email protected] Please provide the following information: 1. The historic, cultural or architectural significance of the site. http://holthouse.dchistoricdesigns.com/ Also see the attached file. 2. A description of the threat facing the site and the immediacy of that threat. The house is in decay and has severe structural issues that threaten it's total collapse within the next few years. 3. Suggestions on what actions are needed to alleviate the threat. The house is in slow decline and immediate attention and funds are needed to structurally stabilize the building before its collapse. There is a need for the Zoo to designate a purpose for the property and incorporate it into its programming. Grants should be sought and private funding is available if the Zoo and Smithsonian would delineate a plan for how the building will be used. 4. A description of how listing on DCPL’s Most Endangered Places list would help the site. This is historically a very important building as well as an early DC architectural gem. Keeping the property in the public's fore front will draw attention to it and allow the Smithsonian to give it a higher priority in its programing than it has received in the past. The Smithsonian needs to step up and help the Zoo develop a sustainable future for this very important, beautiful and historic structure. Historic Holt House (~1810-1814); A Legacy of Wm. Thornton Illustration 1: Holt House - 18891 Introduction Holt House(Ill. 1), located on a secluded promontory in Washington’s National Zoo, is a stately neo-classical structure that has survived the past 200 years with evidence that it was conceived by Dr. William Thornton, the 1st Architect of the Capitol (Ill. 2). Many of Thornton’s contemporaries and founders of the Federal City such as Benjamin Stoddert, Walter Mackall, Thomas Johnson, John Quincy Adams, and Amos Kendall are identified with the property. The house is notable as an important surviving example of a five-part Palladian house plan but with Thornton’s probable influence on its design, and other historic ties, it is therefore an important and intrinsic part of Washington, D.C.’s history and that of the New Republic. Holt House, currently owned by the Smithsonian Institute, was listed in 1973 on the National Register of Historic Places as a” Landmark of importance which contributes significantly to the cultural heritage and visual beauty of the District of Columbia.”2 Recognized as a house of “notable design” in the application; Thornton’s Holt House is one of a few five-part houses, surviving from the Federal Period in the District of Columbia. It is known through his wife’s, Anna Maria’s diary, that Dr. William Thornton often prepared plans and designs for his friends and secured design commissions by virtue of his personal relationships. This paper will explore the design features of Holt House, its history, the prominent people of the era and their relationships with Dr. Thornton, providing evidence that William Thornton created the architectural concept for Holt House. 1 Photo 1889, Smithsonian Institute Archives, Negative #14330 2 Holt House National Register Nomination Form, April 24,1973,p2 1 Illustration 2: Wm. Thornton, 1st Architect of the Capitol3 (1759-1828) Holt House’s Design Holt House is one of the few remaining ‘suburban villas’ in Washington, D.C, a design concept by the 16th century Italian architect, Andrea Palladio. As with Holt House, designs modeled after Palladio’s, incorporated a central block, flanked by symmetrical wings, each consisting of connecting hyphens and end pavilions.

Matthews, after Gilbert Stuart Oil on canvas,1930 3 HABS No.DC-21DC,WASH,128, United States Department of the Interior,p57 2 Holt House is a piano nobile design, an architectural term for the upper floor of a large house, with higher ceilings than the ground floor, containing the main reception rooms. The upper level or main level of this house was originally used as the principal and formal living areas; with the lower level or ground level used as service area and cellar. The upper level featured a large central space in the main block with bed chambers and other family spaces probably in the hyphens and wings. The ground level is thought to have had at least five rooms originally but less finely finished than the main floor and not a full story in height. The west wing had an interior stair that connected the lower floor with the upper floor, probably connecting a ground level kitchen with an upper level dining area. There has been speculation that due to the different methods of construction, including an oversized chimney and bricked up openings, that the west wing may pre-date the rest of the house. It may have been used as a small single family dwelling as the other parts of the house were completed; as was the sequence at both Tudor Place and Arlington House.5 It was the custom in the 18th century, that when an owner was constructing a large house, to first erect one of the wings to house the family until the other portions were complete. This gave the owner a place to live and allowed him to be on-site to supervise the construction. It may have also been built at the time of the Columbia Mills to house a mill manager. Holt House was built of load bearing masonry walls; primarily of brick but intermingled with local stones and rocks. The exterior of the masonry was covered with a white limed based stucco, with a smooth finish and possibly scored to resemble ashlar; similar to the exterior finish of Tudor Place (Ill. 4). 6 Illustration 4: Tudor Place (1805) 5 Fredrick Doveton Nichols, Tudor Place, 1969, p.80 6 Image from Buildings of the District of Columbia,Pamela Scotand and Antoinette J.Lee, New York, Oxford University Press, 1993, p411 3 The central block and matching wings on Holt House have gabled roofs with pedimented façades that are articulated with equally spaced modillions (Ill. 5). The modillions are rectangular blocks or brackets used horizontally in a way that appears to support the roof above. The pediment of the central block, on the north and south elevations, is accentuated with an oculus recess in the masonry. Since there was no attic space or need for light, these recesses may never been glazed but the fashion of the era would have dictated a glazed opening. Illustration 5: Holt House-North Elevation (~1810-1814)7 Originally the north entrance served as the main entrance to the house and was accessed by a stairway from the ground level to the main level’s open porch. Beneath the porch was an enclosed space accessed on both the east and west elevations through arched openings; both arches remain today. The south elevation of the central block, the most prominent elevation, (Ill. 6) was accessible on both the main and ground levels. The main level had an open porch with a parapeted flat roof, which was accessed off the ground level by a pair of matching spiral stairs. The paired spiral stairs were unique to this area but not extraordinary in Palladio’s designs. The main level entrances on both the north and south sides of the central block were three panel double-doors with glazed sidelight sashes. Illustration 6: Holt House-South Elevation (~1810-1814)8 7 Stephen Hansen, DC Historic Designs, Holt House-North Elevation Drawing,2009 4 A significant architectural feature of Holt Houses’ design was the use of Wyatt windows in the south elevation. These tripartite sash windows, with a center sash of six over nine, were a design popularized by the English architect, James Wyatt in the 18th century. The Wyatt window (Ill. 7) is similar to a Serliana or Palladian window, but without a center-arched glazed section. Wyatt windows are found in many houses in the Washington vicinity at the turn of the 19th century. Benjamin Latrobe used Wyatt windows in many of his designs but they were typically adorned with blind arches at the head (a semi-circular recess in the stucco) as seen on the south elevation of the Van Ness House (1813-1816). Thornton used unadorned Wyatt windows at Tudor Place and Holt House. Illustration 7: Wyatt Window Common Domestic Type, c.1810.9 These and other design aspects will be discussed further in a later section devoted to architects and builders in the area at the time of the construction of Holt House. The History of Property Ownership Holt House takes its name from Doctor Henry Holt (Ill. 8) who purchased the house and the land in 1844. 10 Illustration 8: Dr. Holt at South Entrance (1889) 8 Stephen Hansen, DC Historic Designs, Holt House-South Elevation Drawing, 2009 9 Stephen Hansen, DC Historic Designs, Wyatt Window Drawing, 2009 5 The property, on which Holt House sits, is now a part of the Smithsonian Institute’s Zoological Park.
