Double-height stair void of a ground-up new construction home in the Berkeley Hills, CA, as featured on America ByDesign on CBS. The folded ceiling plane - the defining architectural gesture from which the Fold House takes its name — is most clearly expressed in this interior shot. Two birch plywood ceiling planes meet at a diagonal crease above the stair void, one horizontal and one angled, the junction creating a precise dark shadow line that animates the upper volume. Full-height steel-framed glazing at the stair landing frames an unobstructed panoramic view of the Berkeley Hills neighborhood, East Bay flatlands, San Francisco Bay, and Marin headlands beyond.
