 The house features a tower topped by a finial at its northeast corner, a large gable on its rear facade, and a hipped roof with cross gables and a small dormer.

Hyperboloid structures are architectural structures designed using a hyperboloid in one sheet.
 Often these are tall structures such as towers where the hyperboloid geometry's structural strength is used to support an object high off the ground, but hyperboloid geometry is also often used for decorative effect as well as structural economy.
 The first hyperboloid structures were built by Russian engineer Vladimir Shukhov (1853–1939).
 The world's first hyperboloid tower is located in Polibino, Dankovsky District, Lipetsk Oblast, Russia.

The Theodore A. Pappas House is a Frank Lloyd Wright designed Usonian house in St. Louis, Missouri.
 The Pappas house was listed on the National Register of Historic Places in 1979, when it was only 15 years old.
 It is one of two houses in St. Louis designed by Wright, the only Usonian Automatic in Missouri.
 Wright designed it between 1955 and 1959 at the Pappas’ request, and Theodore and Bette Pappas built the house together with the help of day laborers between 1960 and 1964.
 The Pappas house is a rambling four-bedroom house, and after the Gerald B. and Beverley Tonkens House, is the largest of the Usonian Automatics built.
The New Hampshire Apartments in Grand Forks, North Dakota were listed on the National Register of Historic Places in 1982.
 They were built in 1904 at a cost of $26,000 and were significant as a building designed by architect Joseph Bell DeRemer.
 The apartments were an example of commercial vernacular architecture, and the building was the first in Grand Forks to have a planned second-story-level walkway to another building (the Security Building).
 When listed on the National Register, the apartment complex was one of few remaining downtown structures designed by DeRemer with classical details.
 It was built by the Dinnie Brothers, a construction firm that was established in 1881 and was at one time responsible for the building of more than 60 percent of the commercial buildings in Grand Forks.
High Strain Composite Structures (HSC Structures) are a class of composite material structures designed to perform in a high deformation setting.
 High strain composite structures transition from one shape to another upon the application of external forces.
 A single HSC Structure component is designed to transition between at least two, but often more, dramatically different shapes.
 At least one of the shapes is designed to function as a structure which can support external loads.
