Three significant St. Louis homes designed by architects Paul Randolph, William Adair Bernoudy and Isadore Shank were the focus of the recent Sheldon Art Galleries Mid-Century Modern Architecture Tour, chaired by Phyllis Langsdorf and Andrea Powers-Schankman. The event was a sellout, with proceeds benefi tting exhibition and educational programs of The Sheldon, which celebrates its 100th anniversary this year.

The largest structure on the tour, the 6,414-square-foot Horan house on Conway Road, was designed and built by Bernoudy (1910-1988) in 1960. A St. Louis native and University City H.S. graduate, Bernoudy spent one semester at Washington University before leaving to apprentice with Frank Lloyd Wright. Bernoudy is highly regarded for his Mid-Century Modern style that brings together elements of Wright’s Prairie Style architecture with aspects of the International Style, according to architect Andrew Raimist, who conducted detailed research on each of the homes on the tour.

The Horan House is a multilevel structure with a low-pitched roof, solid brick masonry walls and clerestory windows tucked beneath generous roof overhangs.

Among the home’s more striking features are white terrazzo floors, numerous spacious rooms and the distinct horizontal definition of space that lends a comfortable human scale to this otherwise large family home.

Another attractive feature is the generous use of windows on the rear section, which admits natural light into the interior, tempered by the roof overhangs. The soffits of these overhangs extend to the interior of the home, where they become a light shelf and further help define the horizontal nature of the space.

On the outside of the home are private courtyards and balconies distinguished by garden trellis lattice work and balcony railings that provide crisp geometric detail.

Owned and lovingly cared for by the same family since its commission and construction, the home sits on 18 acres and is on the market for the first time in its history with an offering price of $3.499 million.
