About this home
Single Family · Built 1929 · Historic
Situated on a private side street, this grand estate sits on a majestic 2-acres with jaw-dropping panoramic bay views, some of the best in all of Hillsborough. Exquisite architectural detailing and finishes throughout, including inlaid parquet walnut floors, hand carved fireplaces, and walls of glass framing iconic bay views and landscaping. The main level includes a stunning office, billiard hall, and the "Morocco Room" lounge. Upstairs, the large master suite enjoys equally stunning views of the bay, in addition to a luxury spa bath and formal sitting room. A separate in-law suite and wine cellar with tasting room are located on the lower level of the residence. Equally impressive are the surrounding grounds, fully landscaped with grand-scale trees, expanses of manicured lawn, and an elevated terrace overlooking the views and swimming pool. All of this just minutes from shopping, dining, golfing, parks, and top rated Hillsborough schools. (Square Footage Per County Records: 8,629)
