Eichler X-100

One X-100. Seventy years of possibility.

1586 Lexington Avenue · San Mateo Highlands

The X-100 turns the idea of an Eichler into an extraordinary experiment in steel, glass and garden living. Built in 1956 for Eichler Homes and designed by Jones & Emmons, this singular residence brings its structure into view: exposed steel posts and beams, an open plan and daylight reaching deep into the home.

A house designed to explore what comes next

The National Register documentation describes the X-100 as a testing ground for new materials and ideas about living. Steel carries the structure, freeing the interior walls from that role. Skylights illuminate two indoor gardens, while expanses of rear glazing connect the rooms with the landscape.

That combination gives the home its identity: the frame is part of the architecture, the garden is part of the interior, and the spaces unfold around light rather than a conventional corridor.

Explore the architecture

Look for the exposed frame, the indoor planting areas, the relationship between built-ins and circulation, and the way glass extends the living spaces toward the outdoors. This is a private residence; visits are by appointment.
