Elm Court was listed on the National Register of Historic Places in 1979. Portions of the content on this web page were adapted from a copy of the original nomination document. 
Elm Court, the estate of B.D. Phillips, features a forty-room residence built around an enclosed central court and set into a hillside amidst a series of landscaped terraces. The house, measuring approximately 125.70 feet by 159 feet, is of limestone, marble and slate over a steel reinforced concrete frame. Construction, under the direction of Harry Wimer, construction engineer, was begun in early 1929 and completed in mid-1930 at a cost of $3,000,000.
The exterior of Elm Court, picturesquely irregular in configuration, is characterized by numerous typically Tudor features: complex slate roofs with many gables, large groups of rectangular windows, rich oriel and bay windows, interesting chimney treatments, and intricately carved stone detailing.
The interior plan rambles about the central courtyard on two multi-level stories. Finishing throughout the interior is all intact and shows careful attention to detail by the architect, builder, and craftsmen. Rich oak panelling is enriched by linenfold and other decorative carving. Each of the carved interior doors is patterned after a different famous door in England. The house also contains a wealth of stained glass windows, all made in England. The subject matter of the windows in each room corresponds to the purpose of the room. Elaborate metal work throughout the house by Samuel Yellin of Philadelphia includes grilles, gates, sconces, candelabras, torchieres, and chandeliers. The bathrooms are all marble-lined and feature fixtures of silver and gold plate.
The first floor contains an Entrance Hall, flanked by the Library and Study, the Main Stair Hall, a large sunken Living Room, a long Great Hall, a small Sun Room, the Dining and Breakfast Rooms, and the Kitchen and Garage Service areas. (These rooms are strung out in a clockwise fashion around the central court.) The treatment of the Main Stair Hall and Great Hall best reflect the richness of Elm Court. The Main Stair Hall features a landing dominated by a magnificent cathedral-like Gothic window. Carved wooden vaulting in the side hall areas add warmth to this two-story stone-walled space. The Great Hall contains a huge greystone fireplace extending from floor to ceiling and bearing on its apron the sculptured Phillips coat of arms with its motto "Ducet Amor Patriac" (The Love of Our Father Leads Us). A carved Skinner pipe organ dominates one end of the room, and heavy oak paneling on the ceiling is set off by carved transverse beams.
On the second floor are eight guest rooms, the large master bedroom with two adjoining dressing rooms, a sewing room, a music room, and seven bedrooms for employees. Medallions on the windows throughout depict scenes from English literature. Music symbols appear in the music room, and king and queen scenes in the master bedroom suite is topped by a carved figure of a knight bearing a shield.
Service areas are located on the ground and first floors, and living quarters for employees above the garage and service areas. The kitchen and service areas contain their original fixtures. Of particular interest are a Super Service Range made by the Majestic Manufacturing Company in St. Louis and a built-in refrigerator. Two identical hot water gas-fired furnaces on the ground floor guarantees a constant supply of heat to the residence. Garages and shops are located adjacent to the kitchen area.
Like the great English gardens, the landscaping of Elm Court has been developed in an architectural manner as a series of interlocking terraces, high-lighted by walls; and garden houses, which are an extension of the house it-self. The courtyard garden, based on the precedent of European cloisters, contains a geometric pattern of boxwood, ivy, yew, and potted plants. The sunken garden terrace with its central pool, recently filled in but soon to be restored, is entered from a terrace down broad stone steps. It fills the area enclosed by the curving driveway and what is known as "Linden Avenue" with its rows of beautiful linden trees.
Beyond these formal gardens, the natural woodland surrounding Elm Court has been carefully developed. Existing trees were preserved in the original plan and dogwood planted against the background they provided. Also planted in this somewhat contrived woodland were rhododendrons, evergreen azaleas, ferns, evergreen shrubs and ground covers.
Recent work on the house by the architectural firm of Loeffler & Johnson of Pittsburgh has included only repair and restoration measures. No major alterations have been made.
Retaining all of its original fixtures and detailing, Elm Court stands as a rare period piece of the Gothic Revival of the 1920's and 30's. It is also one of only two buildings in Butler by Benno Janssen, the other being a small classical office building for the J.W. Phillips Gas & Oil Company. Benno Janssen (1874-1964), working in conjunction first with Franklin Abbott and later with William York Cocken, was considered to be quite a fashionable designer. In tune with the eclecticism of his time, Janssen worked in both the Italianate — Classical and Romantic country house styles. Best known for his work in Pittsburgh — the Pittsburgh Athletic Association (1901-11), Mellon Institute for Industrial Research (1931-37), the E.J. Kaufmann House (1924-25), and Long Vue Country Club (1922-26) among others — he might be seen at his most creative in this residence. The building is more than a representative example of the Tudor Gothic style of the 1920's and 1930's; it is the architect's superb interpretation of this style which gives it its unusual grace and aesthetic proportion. Janssen's imagination and excellent attention to detail, together with the uninhibited use of materials, craftsmen, and artisans, makes this house truly unique.
Elm Court contains a wealth of art in its English stained glass, limestone relief carvings, carved woodwork, and hand-crafted metal work. All these elements are integral parts of the structural and decorative schemes of Elm Court. Of particular interest is the metal work of grilles, gates, sconces, candelabras, torchieres, and chandeliers created by Samuel Yellin of Philadelphia. Mr. Yellin was a well-known artisan of the 20's and 30's in Philadelphia, whose works may be found at Princeton University, Columbia University, Cornell University, Yale University, University of Pittsburgh, University of Pennsylvania, Bryn Mawr College and many other public and private buildings and homes in the United States. The Philadelphia Museum of Art plans an exhibition of Mr. Yellin's work in 1980. All of the original drawings of the metal work in Elm Court are in the possession of Mr. Harvey Yellin at the Yellin Museum in Philadelphia.
The original landscape work, done by Nicolet and Griswold of Pittsburgh in connection with Benno Janssen, is a fine example of the "period design" in landscaping which corresponded to architectural trends of the era. The entire estate was planted with specimen trees and shrubs which are now mature after 50 years of growth. Aside from aesthetic considerations tied to the architecture of the house and grounds, the trees form an arboretum of sorts as the planting has grown unchanged for 50 years.
Benjamin Dwight Phillips (1885-1968), builder of this estate, lived there from 1929 until his death. The house served as headquarters for his philanthropic endeavors which were mainly architectural in nature. His gifts were used for support and construction of many college and university buildings including Milligan College, Culver Stockton College, Lincoln Christian College, Bethany College, Phillips University, Pepperdine College and Disciples of Christ Historical Society in Nashville, Tennessee. Mr. Phillips was the president and major stock holder of T.W. Phillips Gas and Oil Co. of Butler, PA. This company had previously been the Phillips Brothers Oil Company founded by his father in 1863. Because he shunned publicity much of his generosity was unknown to the general public. Consequently, few people have ever had access to Elm Court. The great majority of his estate in excess of fifty million dollars was left to charity upon his death. During his lifetime, Mr. Phillips never allowed his name to be placed on any of his buildings. Elm Court remains a monument to this generous man.
