Rare, hybrid property has been maintained as a single-family home for decades, and offers the flexibility of a duplex plus an additional detached studio cottage with bath and sleeping loft. This multi-faceted Craftsman home has a huge variety of uses: two separate parties (live in one unit and rent the other out!), intergenerational living, a family home, a full rental, etc. Handsome Craftsman bones and details remain intact. Formal entryway gives way to elegant open living, dining and kitchen quarters. The tranquil backyard with large deck and custom brick patio provide easy indoor-outdoor rapport and space for al fresco dining and lounging. French doors in the sunny rear bedroom connect directly to rear gardens. The main level functions as a nicely separated unit or integrates beautifully for spacious single-family living. Second floor has a large primary bedroom, two additional bedrooms, a TV room/den, full bath and kitchen. Step out on the deck and enjoy a tranquil spot for morning coffee. Just beyond the front door, the beloved Rockridge neighborhood is at your fingertips with a density of dining, shopping, recreation and transportation choices virtually unmatched in the East Bay.
