9509 Heather Rd Originally conceived by acclaimed modernist architect Charles G. Kanner, this exceptional estate has been thoughtfully reimagined and expanded to honor its architectural heritage while introducing a refined contemporary lifestyle. Set behind gates on approximately 2.2 acres at the eastern end of Heather Road's coveted cul-de-sac, a long private drive leads to a residence where architectural pedigree, privacy, and modern technology come together in one of the neighborhood's most desirable settings. Striking entrance canopies lead to a dramatic double-height atrium, where walls of floor-to-ceiling glass flood the interiors with natural light and frame the surrounding landscape. At the center of the home, the formal living room is anchored by a custom wet bar, while a library and theater lined with floor-to-ceiling bookcases offers a more intimate retreat. An expansive family room and private office each open to their own outdoor patios, extending the living spaces into the landscape. A skylit courtyard centered around a mature olive tree connects seamlessly to the chef's kitchen and breakfast area. Custom oak cabinetry, refined stone surfaces, concealed top-tier appliances, and generous prep and gathering spaces create a kitchen equally suited for everyday living and entertaining. The upper level is anchored by a tranquil primary suite overlooking treetop and mountain vistas, complete with a private balcony, oak-paneled sitting room, dual walk-in closets, and a spa-inspired bath featuring a soaking tub, steam shower, and dual vanities. Three additional guest bedrooms complete the second floor, each enjoying views of the surrounding grounds. A detached fitness studio with its own private entrance offers the flexibility to serve as a guest house, wellness pavilion, or creative workspace. Designed for effortless indoor-outdoor living, the grounds feature an elevated pergola with a fully equipped outdoor kitchen, dining and lounge areas overlooking the pool and spa, all surrounded by mature landscaping and peaceful treetop city views. Architecturally significant and meticulously updated throughout, this remarkable Charles G. Kanner residence offers a rare opportunity just moments from Beverly Hills, within one of the Westside's premier neighborhoods and highly regarded school districts.
