Additional Background

An Adventure in Space . . . the tag-line used by developer Clyde Mannon to appeal to the rocket scientists and aerospace engineers working at the nearby Martin Company (today Lockheed Martin). Intended as the successor development to Edward Hawkins’ Arapahoe Acres in Englewood, Hawkins retired early in the project, leaving it in Mannon’s capable hands (having been Hawkins builder at Arapahoe Acres).

Nestled on a hill in Littleton, this neighborhood of semi-custom modern homes has earned its place on the National Register of Historic Places for the quality and preservation of its home designs (most of which are by Denver architect Bruce Sutherland), which take into account indoor-outdoor living, natural light, and respond to the neighborhood’s sloped lots. With a similar design aesthetic as its sister neighborhood Arapahoe Acres, the home designs employ post-and-beam architecture, large expanses of glass, natural materials, low-slope roofs, playful geometry, and unique, yet restrained ornamentation which take cues from Frank Lloyd Wright’s Usonian House concepts and other modern influences of the 1950s and ’60s.

Unlike the design of today’s homes, and consistent with mid-century modern ideas, the houses in Arapaho Hills are meant to be experienced from all sides as a single cohesive design, front-to-back, outside-and-in. To merely drive or walk by only gives you a glimpse into these “Adventures in Space!” This is your chance to see it all by way of an open house tour of multiple homes in the neighborhood.
