This designation places the X-100 among a select group of homes that have not only endured over time, but have helped define the evolution of modern living.

A Rare Level of Integrity One of the key factors in the X-100’s designation is its remarkable level of preservation. Over the decades, the home has been carefully maintained and thoughtfully updated to respect its original vision. Important defining features remain intact, including: The steel-frame structural system The open, garden-centered floor plan Skylights and natural light strategies Signature material palette of steel, glass, and laminate This continuity allows the home to be experienced today much as it was in 1956.

The designation: Does not limit private ownership or resale Does not impose federal restrictions on modifications (unless federal funding is involved) May offer potential incentives or recognition for preservation efforts Instead, it serves primarily as a recognition of significance, elevating the property’s status in both cultural and real estate contexts. A Collector-Level Opportunity For buyers, National Register status adds a layer of meaning that goes beyond square footage or location. It signals that the property is: Architecturally important Historically documented Extremely rare within the marketplace Homes like the Eichler X-100 are often viewed as “trophy properties”—assets that combine lifestyle, design, and long-term cultural value.
