621 Frontenac Avenue

Welcome to The Frontenac, a newly constructed residence in one of Mount Washington's most coveted pockets. Designed by NJD Studio and completed in 2026, 621 Frontenac Avenue pairs warm natural materials and refined architectural restraint with sweeping city and mountain views. The property offers 5 bedrooms and 5 bathrooms across approximately 3,277 square feet on a 9,500-square-foot lot, thoughtfully configured as two fully separate residences. A quiet street leads to a striking yet understated exterior of charcoal siding, a low gabled roof with deep eaves, warm stained wood, and softly illuminated stone steps framed by hedge screens and drought-tolerant landscaping. Inside, white oak paneling, exposed wood beams, skylights, and expansive picture windows create a serene, light-filled environment that feels deeply connected to the surrounding landscape. The main residence features 3 bedrooms, 3 bathrooms, a dedicated office, and expansive living spaces that open through Fleetwood sliders to an approximately 750 square foot deck overlooking the city and canyon. Designed for effortless outdoor dining and entertaining, the deck also offers potential for a private spa, sauna, or cold-plunge retreat. The sophisticated kitchen is defined by floor-to-ceiling cabinetry, paneled appliances, a concealed appliance garage, and a continuous slab of stone extending seamlessly across the island, countertops, and range wall. A dedicated laundry room with custom cabinetry and a marble counter adds everyday ease. The primary suite is a tranquil retreat beneath a vaulted white oak ceiling, with beautifully framed views, a custom-fitted walk-in closet, and a spa-like bath wrapped in full-slab travertine and finished with a floating double vanity and warm, understated lighting. Additional bedrooms are served by generous walk-in closets with custom built-in shelving and drawers. Completely independent of the main residence, the permitted and separately metered ADU residence includes 2 bedrooms, 2 bathrooms, a full kitchen, laundry, and its own private lawn and patio accessed through sliding doors. With its own street-level stair access and no shared entry, the residence offers exceptional flexibility for extended family, guests, a creative studio, or potential income-generating use.Technology and infrastructure have been thoughtfully integrated throughout, including Control4 automation, security cameras, intercom, built-in surround sound, solar, fire-resistant siding, a metal roof, and interior sprinklers. A two-car garage and driveways provide parking for approximately five vehicles, an exceptional advantage on these hillside streets.Moments from Mount Washington Elementary, the trails of Moon and Elyria Canyons, and the restaurants, cafes, and shops of Highland Park and Eagle Rock, with convenient access to Downtown Los Angeles, Glendale, and Burbank.
