A mountaintop lair by Kendrick Bangs Kellogg hits the market near San Diego

On the market for the first time, this sculptural residence by architect Kendrick Bangs Kellogg is a defining example of his organic architecture, in which structure, landscape and light converge. Completed in 1991, the 4,133sqft timber and glass aerie sits high on its 40-acre Valley Center site, northeast of San Diego. It’s listed with Agents of Architecture for $2.995m.

Every element of Kellogg’s design feels hand-shaped to the arid terrain. Curving walls of glass trace the horizon, framing 360-degree views of the surrounding valley, while a composition of wood, stone and concrete blurs interior and exterior thresholds. The open-plan living spaces unfold with a quiet rhythm, anchored by a sculpted fireplace and intimate nooks scaled for daily life. Upstairs, the primary suite opens to a private terrace whose contours echo the rock beneath it.

Reflecting Kellogg’s signature craftsmanship and devotion to place, this one-of-a-kind property stands as both shelter and sculpture — a continuation of California’s radical architectural lineage.
