Welcome to this beautifully updated and reimagined mid-century modern home with a hint of ranch architecture--a stunning single-level El Dorado model offering 3 bedrooms and 2 bathrooms across 1,854 sq. ft. of living space on a 7,665 sq. ft. lot in the highly sought-after Rossmoor community. With vaulted ceilings, open-concept design, and seamless indoor-outdoor flow, this home perfectly captures the essence of Southern California living. Step through the custom front door into a bright, airy interior featuring striking vaulted ceilings, a dramatic floor-to-ceiling fireplace, and expansive windows that bathe the home in natural light. The redesigned open-concept layout creates effortless flow between the living, dining, and kitchen areas--ideal for both everyday living and entertaining. The chef's kitchen is equipped with premium energy-efficient stainless steel appliances, including a 6-burner Viking cooktop, microwave/convection oven, garden window, skylight, and warm butcher block countertops that combine style and functionality. Just off the main living area, a spacious bonus room with custom built-ins and backyard access offers flexible use as a media room, playroom, or secondary lounge. Both bathrooms have been fully remodeled, with the spa-inspired primary bath showcasing new marble tile, modern vanities, and a walk-in shower. The hall bath includes a jetted tub and a solar tube for added brightness. Step outside to enjoy two distinct outdoor living areas: a private front courtyard perfect for al fresco dining, and a spacious landscaped backyard designed for relaxation or entertaining. With only two adjacent neighbors and a tranquil backdrop that enhances privacy, this outdoor space feels like a true retreat. Additional upgrades include seller-owned solar panels (installed 2016) that significantly reduce electricity costs, an upgraded 200-amp electrical service, and a brand-new roof (2023) with a 50-year warranty. A long driveway, manicured lawn, and colorful flower gardens further enhance the home's curb appeal. Ideally located within the award-winning Los Alamitos Unified School District and just minutes from the beach, shopping, golf, and major freeways, this Rossmoor gem offers the perfect blend of architectural character, modern upgrades, and long-term peace of mind.
