One of the most unique properties in all of Mission Viejo-you truly have to see it to believe it. Rarely does a home offer the opportunity to enjoy the functionality and flexibility of what feels like two homes for the price of one. Designed with a private attached ADU that can be separated with its own entrance while still maintaining an interior connecting door, this extraordinary residence is ideal for multigenerational living, extended family, guests, a private home office, or running a home-based business. It also offers exceptional potential for rental income while maintaining privacy for both living spaces. Perched in the highly sought-after New Castille community, this exceptional residence showcases breathtaking near-panoramic views stretching across much of South Orange County. Offering approximately 3,577 square feet of beautifully updated living space, this turnkey home seamlessly blends luxury, versatility, and comfort in one of Mission Viejo's most desirable neighborhoods. The attached private ADU offers approximately 1,250 square feet with direct access from the main residence, creating endless possibilities for today's evolving lifestyles. Whether accommodating aging parents, giving teenagers their own private retreat, welcoming long-term guests, creating a dedicated executive office, or generating supplemental income, this flexible space is truly a rare find. The main residence encompasses approximately 2,327 sq ft and features a beautifully remodeled kitchen, updated bathrooms, upgraded fixtures, enhanced lighting, rich hardwood flooring, and fresh interior and exterior paint. Designed for both everyday living and entertaining, the home features an incredible total of two full kitchens, three spacious living areas, five bedrooms, and five bathrooms. Three of the five bedrooms open onto private view decks, providing spectacular panoramic vistas that stretch across Orange County. Relax in the spa while enjoying unforgettable sunsets, discover the hidden room perfect for a wine cellar, tasting room, hobby space, or additional storage, and appreciate the thoughtfully converted side-yard carport with garage door, offering even more secure parking and flexibility. An abundance of storage throughout the home easily accommodates even the largest of families. Expansive windows fill the home with natural light while framing the spectacular views from nearly every angle. Residents enjoy exclusive membership to Lake Mission Viejo.
