The Seamour and Gerte Shavin House is a Frank Lloyd Wright designed Usonian home in Chattanooga, Tennessee.
 The house was added to the National Register of Historic Places in 1993.
Frank Lloyd Wright (born Frank Lincoln Wright, June 8, 1867 – April 9, 1959) was a first generation Welsh-American architect, interior designer, writer and educator, who designed more than 1,000 structures, 532 of which were completed.
 Wright believed in designing structures that were in harmony with humanity and its environment, a philosophy he called organic architecture.
 This philosophy was best exemplified by the Fallingwater house (1935), which has been called "the best all-time work of American architecture".
The Charles W. Merrill House is a 6,000-square-foot residence designed by regionally prominent architect Walter H. Ratcliff, of Berkeley, for mining engineer and San Francisco businessman Charles Washington Merrill.
 Built in 1938, the house's architecture reflects elements of the Spanish Colonial Revival, but with its two stories, low-pitched roofline, and second-story balcony on the front elevation, the house is most characteristic of the Monterey style popular in large California homes built between 1925 and 1940.
 The house and grounds were designed as a small country estate.
 The house occupies a hillside location and is sited on two stonework terraces, pierced by three stone staircases placed among gardens designed by landscape architect Mabel Symmes in 1938-1939.
 The house is significant under Criterion B for its association with the final stage of Charles W. Merrill's long and distinguished career.
 Merrill lived in the house during the period in which he presided over a highly diversified engineering corporation, with worldwide influence, that had grown from Merrill's pioneering patents and discoveries of the 1890s and 1900s.
 The house also is significant under Criterion C as an example of the eclecticism that architect Walter H. Ratcliff brought to his architecture.
 Built in the mature phase of Ratcliff's career, the Merrill House with its elements of Spanish Colonial Revival and Monterey styles reflect Ratcliff's distinctive blend of academic eclecticism and keen awareness of regional topography, climate, and setting.
The Dwight Perkins House is a historic house located at 2319 Lincoln Street in Evanston, Illinois.
 The house was built in 1904 for architect Dwight H. Perkins and children's author and illustrator Lucy Fitch Perkins.
 Perkins designed his house in a style heavily influenced by the Prairie School and the Arts and Crafts Movement.
 The house was built from wood and stucco, materials characteristic of both styles which let the house blend into the surrounding nature.
 Its exterior decorative features include bracketed eaves, casement windows, trellises, and a half-timbered gable.
 Landscape architect Jens Jensen, a friend of the Perkinses, designed the house's surroundings, which include a reflecting pool.
 The inside of the house incorporates horizontal bands of windows which let in sunlight, unpainted wood features, and an open floor plan.

Obed Taylor (April 27, 1824 - August 2, 1881) was an architect who designed many notable buildings in early Utah that survive on the National Register of Historic Places.
 Taylor's works include the Salt Lake Assembly Hall on Temple Square, the Salt Lake 18th Ward meetinghouse, and Ogden's Z.C.M.I. and First National Bank Block.
 Though Thomas L. Allen has been credited with being the architect of the Summit Stake Tabernacle, Taylor approved of the plans and likely assisted Allen who was untrained as an architect.
 Obed Taylor worked in partnership with William H. Folsom on many projects including the Deseret National Bank, ZCMI's cast-iron storefront (1876), and the Feramorz Little residence.
 He died at the height of his architectural career in 1881.
 Funeral services were held in the Salt Lake 18th Ward meetinghouse which he had recently designed.
 The Walker Opera House as well as a building at the University of Deseret were designed by Taylor but completed after his death.
