Charles Warren Callister’s Barrel-Vaulted Duncan House Lists in San Francisco for $7.9M

176 Palo Alto Avenue in San Francisca, California, is currently listed at $7,900,000 by Neill Bassi at Sotheby's International Realty - San Francisco Brokerage.

Commissioned in 1959, the Duncan House stands as a quintessential expression of Northern California modernism. Designed by Bay Area architect Charles Warren Callister, the Clarendon Heights residence pairs structural drama with an acute sensitivity to site and elevation. 

Perched high above the city, the home’s defining architectural gestures—barrel-vaulted timber ceilings and expanse-spanning, floor-to-ceiling glass—frame uninterrupted, panoramic views of San Francisco and the bay.

A recent sensitive restoration updates the interiors with custom finishes while preserving Callister’s original interplay of warmth, volume, and light. It remains a rare, highly preserved artifact of midcentury architectural heritage in one of the city's most elevated enclaves.
