8321 La Sierra Ave, Whittier, CA 90605

Tucked in the Prestigious Woods of Friendly Hills | Versatile Estate with Separate Apartment. Welcome to 8321 La Sierra Avenue—an exceptional property located deep in the prestigious Woods of Friendly Hills, one of Whittier’s most established and desirable neighborhoods. Set well off the street at the end of a tree-lined driveway, this custom 1987-built home offers space, privacy, and a layout designed for flexible living. Spread across three levels, this residence blends original character with potential for the next owner to restore or reimagine. The entry-level opens to a formal foyer and a large, open living room with expansive windows that frame the peaceful front yard. Also on this level: a dedicated office, powder bathroom, formal dining room, and an en suite bedroom with its own full bath—ideal for guests or single-level living. The kitchen, modest in size but full of charm, opens to a cozy family room with French doors that lead to a spacious wraparound deck overlooking the large backyard. It's an easy, comfortable space for day-to-day living or casual entertaining. Upstairs, the private primary suite includes a generous walk-in closet, full bath, and direct access to a balcony—perfect for enjoying morning coffee or the evening sunset. Three additional bedrooms, each with their own private bathroom—including a shared Jack-and-Jill layout—complete the top floor, along with hallway storage. On the lower level, an additional 1,100 square foot, one-bedroom apartment offers its own private entrance, full kitchen, dining area, two flexible living spaces (one ideal for an office), 3/4 bath, large walk-in storage closet, laundry hookups, and direct access to a separate two-car garage. This self-contained apartment provides excellent income potential or the perfect space for extended family, guests, or live-in help. The gross total of living space between all three levels is nearly 5,700 square feet. While this home is being sold in original condition and offers the opportunity for thoughtful updates, its generous footprint, custom layout, and location within The Woods make it an exceptional find. Don’t miss the chance to own a truly unique property in one of Whittier’s most sought-after neighborhoods—where homes rarely come to market and possibilities abound.
