Property Description

An authentic Mid-Century Modern, the Kellogg House is a standout on Potrero Hill. Built in 1948 by F.J. McCarthy, the home was extensively expanded in 2015 on a double-lot near the top of the coveted North Slope with panoramic views of the City skyline. The main level is surrounded by landscaped terraces and gardens, and reveals an open kitchen, dining, lounge, fireplace and media areas, all capturing the views. At the top of a floating staircase, a full-floor primary suite features a covered terrace with gas fireplace, walk-in closet with picture window, and bath with garden overlooks. The lower level is comprised of 2 bedrooms, a full bath, laundry, and 2-car garage with EV charging, and integrates a wellness retreat with outdoor shower, hot tub, and sauna, all surrounded by mature trees. Elegant and timeless, this iconic residence features the rare combination of Mid-Century design, indoor/outdoor living, views, and ease of access to neighborhood cafs, downtown, and Silicon Valley.
