Designed by Jim Jennings Architecture, this one-of-a-kind architectural marvel is situated on an expansive parcel in Telegraph Hill, offering stunning views of the Golden Gate Bridge and the Bay. At the heart of the home is a 50-foot concrete cylinder accentuated by glass bridge walkways and a glass ceiling that serves as a rooftop terrace, revealing striking architecture and soaring ceilings. Nearly every room includes direct access to outdoor space with rectangular Bay windows extending from the building's envelope with hidden pocket doors. Designed to display fine art, the interiors feature plaster walls applied over plywood, reminiscent of museum surfaces. Multi-zone AC and heated concrete floors grace the main level, while the upper levels are finished with polished maple finishes. The floor plan is exceptionally flexible and ideal for single residents or multi-family use. Entry-level bedrooms can be independent apartments or family, fitness, recreation, or office spaces. The primary suite on the third level includes a sizable room perfect for an office. Entertaining spaces are designed to accommodate large gatherings and private conversations, with immediate access to outdoor spaces. Multiple landscaped garden venues.
