Designed by George Watts Carr and built for James Cobb, Pinecrest was purchased by the Duke family in 1934. It was, until 2012, the home of Mary Duke Biddle Trent Semans. From the National Register Listing:
The Mary Duke Biddle Estate is located at 1044 and 1050 West Forest Hills Boulevard along the western edge of the fashionable early-twentieth-century Forest Hills subdivision in the City of Durham, North Carolina. It is [...] situated prominently on land that rises to a plateau above Forest Hills Park. Comprising 8.562 of the 13.17 acres assembled during the mid 1930s and 1940s by Mrs. Biddle, the estate is an irregular parcel of land bounded by Kent Street on the west, neighboring properties on the north and south, Westwood Drive on the southeast, and Forest Hills Boulevard and Forestview Street on the east. Fences delineate roadside boundaries, and forested groves and bamboo thickets largely obscure the buildings, structures, and grounds from view.
Set back several hundred feet from Forest Hills Boulevard and Forestview Street atop an east- facing hill, “Pinecrest” the focal point of the estate, is a large and handsome Tudor Revival dwelling designed by Durham architect George Watts Carr Sr. in 1927 for Forest Hills developer James O. Cobb. From 1935 through 1958, extensive additions and interior renovations made to the dwelling for Mrs. Biddle under the direction of New York designer Karl Bock included Colonial Revival, French Eclectic, Oriental, Art Moderne, and Art Deco elements.
Bock also made plans for Mrs. Biddle’s auxiliary housing and recreational and landscaping needs. During the late 1930s and early 1940s, he designed and supervised the construction of one additional dwelling, and designed or planned for the installation of three outbuildings and nine structures that contribute to the historic character of the property.3 The Cottage (5) at 1044 West Forest Hills Boulevard, constructed in the English Cottage style, compliments the original Tudor Revival style of Pinecrest. A much smaller dwelling, it has an attached garage and was constructed near the northeast boundary of the property to accommodate servants and automobiles. A gasoline pump (6) was installed adjacent to and west of the garage. A cast iron picket fence with two ornamental gates (7) was erected along West Forest Hills Boulevard.4 Two large brick arches (2 & 3) were erected northwest and southwest of Pinecrest to mark the beginnings of footpaths that interconnect on the grounds of the estate. A picnic area with a stone fireplace and a nearby wading pool fed by streams that emerge from stone- lined grottoes (4) were created northwest of Pinecrest in a grove of trees. A recreational complex with a bathhouse (8) tennis court (9), a swimming pool (10), and a stone fireplace (11) was constructed southwest of Pinecrest near the west boundary of the estate. An extensive pergola (12), a gardener’s cottage with an attached greenhouse (13) and a storage garage (14) were added west of the dwelling along Kent Street. Ornamental shrubs, small fountains, birdbaths, and statues dot the estate though an elaborate rose garden once situated west of the house no longer exists.
Two non-contributing structures, a contemporary metal storage shed installed northeast of the storage garage (15) and an early-twentieth-century playhouse recently placed in a garden northwest of Pinecrest (16) do not distract from surrounding historic resources.
Pinecrest, The Cottage, the gardener’s cottage and greenhouse, the gardener’s garage, the swimming pool, the bathhouse, and the tennis court are listed on the National Register as contributing within the Forest Hills Historic District (NR 2005).
