Architecture worth looking at closely
A prototype with a life of its own.
The X-100 was built in the San Mateo Highlands in 1956 as an experimental steel house by Jones & Emmons for Eichler Homes. Its architectural history, subsequent restoration and National Register recognition are documented by the home’s history website.
The film is your first encounter. A visit is the opportunity to study how its structure, openings and spaces work together—and to consider what stewardship of a distinctive home means for you.

The renewal project / 2016–2017
Restoration with a point of view.
The documented X-100 Renewal Project, completed in 2017, brought together owner Marty Arbunich, project managers Lucile Glessner and JC Miller, and a team of specialist trades. The work addressed both the home's architectural character and its landscape.
Recover the original idea.
The project restored the carport by removing a garage door and uncovered original wood siding beneath metal cladding.
Work through the details.
Pool and decking restoration, custom gates, lighting, paint and furnishings formed part of the coordinated renewal.
Follow the evidence.
The project archive documents the decisions and progress photographs. Its improvement gallery follows 11 phases of the work.

The Property Nerds viewing lens
Look past the first impression.
Follow the structure.
Look at where the steel is expressed, how the roof reads across the rooms and how the structural rhythm shapes the view. Architecture becomes easier to understand when you follow the lines.
Watch the edges.
Notice the relationship between glass, garden and living space. During a showing, pause at the transitions and compare the experience of looking out with the experience of moving through.
Imagine the everyday.
Bring your routines into the conversation: where you would read, gather, work and spend time outdoors. An architectural home should reward both close observation and daily use.
Before your private visit
Bring curiosity. Ask specific questions.
- Property information: Request the current offering details, floor plan, disclosures and available inspection records from the Boyenga Team.
- Restoration and care: Ask which records document completed work, what maintenance is recommended and which specialists may be appropriate.
- Future plans: Discuss any changes you are considering with qualified professionals and the relevant local authorities before relying on assumptions about feasibility.
- The showing: Share your timing and the aspects of the home you want to understand, so your visit can focus on the details that matter to you.
Price, availability, property measurements and showing arrangements should be confirmed directly with the listing team. This architectural introduction is not a substitute for the current listing documents.
