The Johnson house, Pierre Koenig’s only building in Northern California, was built on a 20-by-20-foot grid. Glass curtain walls open the house to the landscaping and expansive views. A see-through central fireplace forms the centerpiece of the open-plan living-dining area.
Koenig’s additions in 1988 included two new bedrooms, filling the former carport and entry, and providing a new carport in an added wing. The project also involved stripping away a dropped ceiling, wood veneer paneling that hid the steel siding, bay windows, and Victorian-style beveled-glass doors.
“It’s absolutely, completely functional and complete and honest in the delight of its revealed structure. It’s so simple and beautiful, so unadorned. It’s direct and a joy to live in,” Cynthia Riebe says of the house. “I love the night light and how it changes, and the reflections through the interior and the exterior. There’s no boundary between the two.”
The house was restored and expanded by Cynthia and Fred Riebe during the 1990s with the help of Koenig himself. Structure: Steel-framed and steel-sided. The ceilings and exterior walls are unadorned, corrugated steel decking. Laminated wallboard sheathes the interior walls.
