Designed by celebrated architect Willis Polk for his chief engineer, T. Ronnenberg—who later worked as a structural engineer on both the Golden Gate and Bay bridges—20 Oak Ridge Road combines architectural elegance with an exceptionally livable floor plan in approximately 4,119 square feet. The main level is devoted to living and entertaining. A gracious entry leads to beautifully proportioned rooms, including an expansive living room with fireplace and an a stunning adjoining sunroom with arched windows and tiled floors. A formal dining room connects to the thoughtfully designed kitchen, offering abundant storage, a breakfast nook and convenient side access through the mudroom. A powder room (not to be missed!) completes the level. Upstairs are three bedrooms and two full baths, plus a separate sitting area and office—an especially appealing layout. The generous, light-filled primary bedroom enjoys treetop and hillside outlooks, while the sitting area and office offer dedicated spaces to work or retreat. The two additional bedrooms share a thoughtfully designed bath. The lower level offers a private en-suite bedroom for guests, a comfortable family room for gathering and hanging out, and a flexible room currently used as an office/gym. A half bath, laundry, wine cellar and substantial storage add to the versatility. Exceptional interior design brings a contemporary point of view to Polk’s architecture. Paneled walls, a sculptural staircase and graceful windows complement thoughtfully selected lighting, color, furnishings and updated baths. The result is elegant without being formal—a sophisticated home equally comfortable hosting teenager hangouts, work events and pool parties. Outside, a heated swimming pool, expansive terraces, patios and mature landscaping create inviting spaces for dining, lounging and entertaining. Convenient access from Tunnel Road makes outdoor gatherings especially easy. Energy Score is 1 Directly across from the Claremont Hotel, the home is exceptionally convenient to neighborhood shops, La Fournée, Peet’s, restaurants (including the Station and the soon to open new diner!). If you use the “secret” Oak Ridge Path to Domingo you will get there even faster!
