* ENTERED FOR COMP PURPOSES ONLY * Stunningly romantic in a serene setting, The Flagg Cottage'' was designed by Bernard Maybeck for UC Berkeley professor Isaac Flagg. Some years later, , an addition by architect Thea Robertson expanded the property. The two separate wings of the house are joined by public rooms, which include an elevated living room offering views of the SF Bay, an updated chef's kitchen, one half bath, and access to the rear gardens. The right wing holds the primary bedroom suite with a stone fireplace and a private entrance, a downstairs office/library as well as a formal dining room with a wall of built-ins. The left wing has an ensuite bedroom, one additional bedroom, and interior access to the garage. The unexpected viridian slate floors of the foyer and kitchen, and the kitchen's viridian colored soapstone countertops provide a keen accent to the wood interiors. The property enjoys two driveways, a separate workshop, a garden potting shed, and a rear garden terrace made of flagstone.

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.
