Located on a premier block, this distinguished residence presents a rare opportunity to reimagine a significant Presidio Heights home of exceptional scale and architectural character. Built in 1900 and designed by notable architect Edward R. Swain, the fully detached home spans approx. 7,350 sqft across four levels on an extraordinary 60-ft-wide lot. Abundant natural light, original oak floors, 11-ft+ ceilings on the main two levels, seven wood-burning fireplaces, original light fixtures, and intricate period millwork reflect its turn-of-the-century origins. The grand foyer is enveloped in original wood paneling with stained glass, a fireplace, and integrated built-in seating. Adjacent, the gracious living room is defined by grand proportions, elaborate crown molding, and original oak floors. Beyond, a striking sunroom wrapped in arched windows leads to the formal dining room with a box-beam ceiling, wainscoting, original built-ins, and partial Golden Gate Bridge and Bay views. The generously proportioned kitchen and breakfast room enjoy Bay views and open to a view terrace, complemented by a butler's pantry and powder room. A grand staircase with an intricately carved wood balustrade and dramatic windows leads to the bedroom level with three bedrooms and a remarkable library. Sweeping Golden Gate Bridge, Bay, and Presidio views provide a backdrop to the library, distinguished by a coved ceiling with intricate plasterwork, original built-ins, wet bar, and stained glass. The south-facing primary suite features herringbone oak floors, a wood-burning fireplace, dressing room, and en-suite bath, while two additional bedrooms enjoy views and original Victorian fireplaces. The upper level of the home features two additional bedrooms and a full bath. The expansive lower level extends the home's living and entertaining spaces, with a generous family room opening directly to the garden and a spacious game room with wainscoting and an original fireplace. An additional bedroom and full bath provide private guest accommodations, while a laundry room, bonus room, and powder room offer additional flexibility. The expansive two-level garden is framed by mature greenery and a stately pine tree, offering a private outdoor setting with partial Bay views. A two-car side-by-side garage with interior access is complemented by a spacious private driveway. Ideally located on a tree-lined street near the Presidio, the boutiques and restaurants of Sacramento St, & Laurel Village.
