901 Isabel St Historical Cultural Monument No. 849. This architecturally significant residence, known as The Nickel-Leong Mansion (1905), was designed by John C. Austin, architect of the Griffith Observatory and Los Angeles City Hall. Perched on a Mt. Washington hilltop, this extraordinary Greek Revival estate showcases immaculately preserved architectural details including hardwood floors, crown moldings, built-in benches and bookcases, and exquisite millwork, the kind of character and craftsmanship rarely found today. Framed by historic and rare Bunya pine trees, the neoclassical facade opens to a sunlit interior with a grand foyer, soaring ceilings, generous rooms, and a classical symmetrical floor plan. The spacious living and dining rooms feature large picture windows with gorgeous views and a focal fireplace in each room. The main level also includes a newly remodeled, vintage-inspired chef's kitchen complete with stainless steel appliances; a study with original oak millwork; generous hallways; a classic penny-tile bathroom; a large laundry room; a basement; and a separate garage. Upstairs are four generous bedrooms, including a sweeping, sun-soaked primary suite. Ascend a winding staircase to the large finished attic perfect for a creative studio, gym or play space. Set on over half an acre, the property features multiple private decks and outdoor terraces for dining, lounging, and entertaining. Located near the vibrant mix of hip retail shops, restaurants, and art galleries on Cypress Avenue, including Loquat, Caf Antonietta, Barra Santos, and The Golden Poppy Market.
