Hopkins studied at the
Ecole des Beaux Arts in Paris followed by several years in Rome completing his knowledge of architecture, presumably in the early 1890s. By 1898, he returned to New York City and was practicing as an architect. Early in his career, Hopkins specialized in the design of farming complexes for the American capitalist during the Gilded Age. By 1900, he was designing a new farm group for
Frederick W. Vanderbilt in Hyde Park, New York in association with
Edward Burnett (1849-1925), an agricultural specialist who earlier developed and managed the farming operations for other members of the
Vanderbilt family. Hopkins and Burnett maintained an office at 11 East 24th Street in New York City. Together they designed some of the country's most extraordinary farms, including Foxhollow, the Tracy Dows estate in Rhinebeck, New York, and a farm for Harry J. Fisher in Greenwich, Connecticut. Their collaboration, though not firmly documented during this time, probably resulted in several other farm projects associated with Hopkins New York, New Jersey, and Massachusetts. Their work, particularly Hopkins architectural style, established the standard for farm architecture and influenced an entire generation of architects. In 1913, he severed his association with Burnett and established himself as Alfred Hopkins & Associates located in the Architects Building at 101 Park Avenue in New York City. Hopkins continued specializing in gentlemen's farms, quickly establishing himself as the "dean of farm group architecture," due in no small part to the success of his
Modern Farm Buildings, first published in 1913 (dedicated to Edward Burnett) and two subsequent editions (with the Burnett dedication omitted). Hopkins farm groups appeared in Westchester County, New York, the Hudson River Valley, northern New Jersey, Illinois. He designed no fewer than fifteen farm groups on Long Island, including the farm at
Laurelton Hall for
Louis Comfort Tiffany. An article on farm groupings published in
Architectural Record in 1915 notes that Hopkins was often called upon to design the farm groups on estates where the residences were the work of other architects, such as
Bertram Goodhue,
John Russell Pope and
Charles A. Platt. Hopkins was among the contributors to
Stables and Farm Buildings: A Special Number of the Architectural Review produced by the staff of
Architectural Review in 1902. His
Modern Farm Buildings served to publicize his practical and picturesque esthetic, and in common with all
architects' publications since the sixteenth century, to attract clients. Hopkins' book went into a third edition. Hopkins laid out his farm buildings around paved courts or grassed paddocks, keeping rooflines and eaves low to blend with the landscape, and carefully separating the necessary farming functions. He preferred to remove hay storage from its traditional loft over the stables to eliminate dust infiltration and ammonia pollution. Open-sided sheds housed farm vehicles. The spatial routes of cows and horses were kept separate. Farmhands' quarters were integrated with the buildings. An outstanding late survival of Hopkins'
Cotswolds-inspired vernacular manner is the stable court at
Hartwood, near Pittsburgh (1929). The same year he published a brochure distributed among architects,
Two Cotswolds Villages, describing the vernacular architecture and stone-tiled roofs of two picturesque English villages:
Bibury, Gloucestershire and
Castle Combe, Wiltshire. Hopkins is less known for his
Prisons and Prison Building (New York: Architectural Book Publishing 1930), where rational planning met other ends, in a progressive and humane program based on the classification of prisoners and their segregation by groups in small units; proposals that argued against walled prisons and for the uplifting effect of good architecture. His practical experience was founded on his work at Westchester County Penitentiary, Berks County Prison, and his proposed designs for a federal prison to be built at Lewisburg, Pennsylvania,
Lewisburg Federal Penitentiary, completed in 1934. Hopkins was also among the architects who published plans for inexpensive carpenter-built housing in
Carpentry and Building. and his small book
Planning for sunshine and fresh air: Being sundry discourses & excursions in the pleasant art of building homes, set forth in a manner and upon a theory ... how best to effect their proper economies appeared in 1931. In the 1920s and 1930s Hopkins was associated with architect John G. Dentz in the firm of Hopkins & Dentz, which developed a specialty in the design of large bank buildings, including the
Buckeye Building in
Columbus, Ohio and the
Boji Tower in
Lansing, Michigan. He published
The Fundamentals of Good Bank Building in 1929. After an interim following his death, an architectural firm was founded in 1954 by six associates from his office, as La Pierre, Litchfield & Partners. ==Some characteristic projects==
