Designed by esteemed early-20th-century architect Edgar A. Mathews and built in 1903, this five-bedroom, 8,520-square-foot residence exemplifies San Francisco’s unique enduring style. On one of the city’s most desirable blocks—steps from Alta Plaza Park in Pacific Heights—it is set back from the street for privacy and enjoys partial views of the bay. The grandly scaled four-level interiors are replete with thoughtful built-ins—from window seats to bookshelves—with hardwood floors and leaded-glass windows contributing to a sense of time-honored refinement. The public spaces, located on the main level, include a generous living room with a wall of windows, built-in seating and bookshelves, and a fireplace; a formal dining room with a wall of windows and access to the backyard; a wood-paneled library; a spacious kitchen with Carrara marble and butcher-block countertops, Sub-Zero and Wolf appliances, and a breakfast area; and a cheerful sunroom that also opens to the lush backyard. The glorious rear gardens offer an idyllic escape of colorful seclusion with a stone tile terrace, manicured hedges and plantings, and tall trees. One of three bedrooms on the third level, the master suite includes a light-filled sitting room with a fireplace, bookshelves, and a wet bar as well as a spa-like bath with a pair of walk-in closets, a dual-sink vanity, a glass-enclosed shower, and a soaking tub. The uppermost level offers a versatile room that currently serves as an office and features built-in shelves and desk space, a full bath, and a view of the Golden Gate Bridge and the bay. Each of the two top-floor bedrooms has French doors to a sunny south-facing deck. On the entry level, an open, welcoming foyer gives way to a gallery, a billiards room and gym, and a handsomely appointed family room with a media area, a wet bar, a powder bath, and access to a discreet alfresco hot tub. Completing the home is the one-car garage with storage. Located on a beautiful tree-lined street within a short walk of restaurants, shops, Alta Plaza Park, and many sought-after schools.
