An architecturally daring and significant home designed by Pierre Koenig surfaced on the open market this month priced at $4.385 million. Koenig was one of the Case Study Program architects, and designed CSH #21, the Bailey House, and #22, the Stahl House. The Bailey was offered for sale late in the last decade, and sold about two years ago for $3.3 million.

This page from Koenig’s portfolio is located in Santa Monica, and called the Schwartz House. A later build, it went up in 1994. The home’s exterior uses steel and frosted glass, and there’s a great deal of industrial design in the architecture, including a playful offset framework that supports the structure and adds a small bedroom terrace to the façade. At ground level, living areas include an office, with pocketing glass walls. But most of the living space begins on the second floor.

Warm hardwood floors and glass begin the main living area of this house—a wall of glass illuminated the combination dining, living and kitchen area and brings some green into the common space. The eye-catcher is the spiral staircase that transitions from public to private accommodations—canary yellow galvanized steel treads, a gray industrial balustrade, and a black pole.
