About this home
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!

Claremont, located between the Berkeley Hills and Rockridge, is a residential and hillside Berkeley neighborhood with Craftsman streetscapes and canyon-side trails. The neighborhood’s character concentrates around the Claremont Avenue and College Avenue corridor, where sidewalk cafes, small boutiques, and a steady stream of walkers set an unhurried pace. The Claremont Club & Spa anchors the area with a classic resort profile, while the Claremont Branch Library adds a civic, bookish counterpoint. Homes step up the slopes in shingled and Tudor-tinged forms, with mature trees softening the blocks. Paths and stairways stitch together pockets near Claremont Canyon Regional Preserve, and the air shifts cooler as the grade rises.

Designed by renowned architect Willis Polk in 1915, 20 Oak Ridge Road is a dramatic and utterly exquisite 5BD/4.5BA home graced by many of the hallmarks of a European aesthetic: balconies, patios, and sunrooms, distinctive architectural details, and a sparkling pool. Known in the neighborhood as “The Gatsby House,” 20 Oak Ridge is generously proportioned and light-filled. It is ideally situated on a sought-after cul-de-sac overlooking the Claremont Hotel, and it is steps from exquisite amenities yet stuns with a private, estate-like sensibility.

Single Family Residential District - Hillside Overlay Zone
The purpose of the Single-Family Residential (R-1) district is to: Recognize and protect the existing pattern of development in the low-density, single-family residential areas of the city consistent with the General Plan; Make housing available for persons who desire detached housing and a relatively large amount of usable open space; Protect adjacent properties from unreasonable obstruction of light and air; and Permit community facilities such as religious assembly uses, schools, parks, and libraries which serve the local population and are not detrimental to the immediate neighborhood.; The purpose of the Hillside (H) overlay zone is to: implement General Plan policies for hillside development; protect the safety and health of residents where steep topography, unusual street conditions and proximity to the wildland-urban interface create severe risk from wildfire; protect the character of Berkeley's hillside areas and their immediate environs; give reasonable protection to views yet allow appropriate development of all property; and allow modifications in standard setback and height requirements when justified because of steep topography, irregular lot pattern, unusual street conditions, or other special aspects of the hillside areas.
