Built in 1948 by architect F.J. McCarthy, the Kellogg House is named after its original owner, and in its first in incarnation, stood two stories with two bedrooms and two-and-a-half bathrooms. The house remained largely intact for the next 45 years until 2015 when Sacramento-based Serrao Design and Architecture gave it more modernist appeal with the addition of a full-floor penthouse level primary suite with a covered terrace, one more bedroom, a wellness center with an outdoor shower, multiple decks, and louvers aplenty.

Spanning a double lot near Potrero Hill's North Slope, the residence offers panoramas of the city from Twin Peaks to the Bay Bridge. Find rotating vertical shutters that open to floor-to-ceiling glass walls for taking in the landscaped terraces and succulent gardens that surround the home.

On the main level, the heart of the home consists of a large kitchen with a center island, dining area, lounge, fireplace and media areas. Take in glorious views of the city from a north-side wall of glass. Up a floating staircase is the primary suite level with its own covered patio with a gas fireplace, walk-in closet, and dressing room. Find two more bedrooms, a full bathroom, and laundry room on the lower level, which also has access to the two-car garage as well as the front and rear gardens. Outside is a soothing sanctuary with a hot tub, infrared sauna, and the outdoor shower. Enjoy a sweat and a soak amid a grove of acacia and eucalyptus trees.
