The Kellogg House

An authentic Mid-Century Modern home featured in numerous architectural publications, the “Kellogg House” is a standout on San Francisco’s Potrero Hill. Built in 1948 by architect F.J. McCarthy for the Kellogg family, this three bedroom home is designed for gracious indoor/outdoor living. Sited on a rare, double-lot near the top of Potrero Hill’s coveted North Slope, the Kellogg House delivers unparalleled views of the City skyline, from the Bay Bridge to Twin Peaks.

The original design and layout – with an emphasis on seamless indoor/outdoor living spaces and clever elements such as rotating vertical shutters opening to reveal floor-to-ceiling glass walls – was thoroughly restored, refreshed and expanded by Serrao design | architecture in 2015, enabling the Kellogg House to step gracefully into the 21st Century.

Surrounded on all sides by landscaped terraces with succulent gardens, the main level reveals an oversized  kitchen with center island, dining, lounge, fireplace and media areas. This level’s focal point is a north-side wall of glass showcasing dramatic City views. At the top of a floating staircase, a full-floor primary suite features a bedroom, covered outdoor terrace with gas fireplace, and fully outfitted walk-in closet and dressing room. The adjacent primary bath features garden overlooks and timeless elements of modern design.

The lower level, with direct access to the greenery of the front and rear gardens, is comprised of two bedrooms, a full bath, laundry room and two-car garage, complete with EV charging stations. The terraced gardens artfully integrate a spa-like wellness retreat, showcasing an outdoor shower, hot tub, and recently-installed infrared sauna. A true sanctuary, the terrace and lawn areas are surrounded by mature Acacia and Eucalyptus trees.

Elegant and timeless, the iconic Kellogg House features the ultra-rare combination of Mid-Century design, balanced indoor/outdoor living, exceptional panoramic views, and ease of access to neighborhood restaurants and cafés, the city center, and Silicon Valley…creating the ultimate in modern San Francisco living.
