Tucked inside a classic Edwardian building on a beautiful, tree-lined block in Presidio Heights, this garden-connected flat blends timeless San Francisco architecture with warm, modern living. The sophisticated house-like condominium occupies the lower level of an elegant three-unit building and offers approximately 1,700 square feet of beautifully scaled living space. The main level includes two bedrooms and two baths, including a primary suite with a thoughtfully remodeled en-suite bath, along with a flexible den or office currently used as a third bedroom. At the rear of the home, the space opens dramatically into the home's gathering rooms - a gracious living room with fireplace and built-ins, a large remodeled kitchen with custom millwork, and a comfortable family room. These rooms are all oriented toward a wall of windows and glass that overlook the balcony and garden below, with Nano doors that create a seamless connection between indoors and out. A spiral staircase leads down to the patio and garden, a peaceful green retreat that feels wonderfully private. Just off the garden is a deeded bonus room with a remodeled bath - heated, carpeted, and complete with a closet and sliding doors to the patio. Ideal as a guest suite, office, gym, or creative studio. Additional highlights include in-unit laundry and a large ground-level storage room with a wine cellar cooler, perfect for collectors and entertainers alike. Set among Presidio Heights' storied homes and leafy streets - and just moments from the neighborhood's beloved parks, shops, and cafes - 3446 Clay offers the rare feeling of living in a house while enjoying the ease of a boutique building.
