Agent Remarks

Situated within the prestigious 24-hour guard-gated community of Altair, this Toll Brothers Helios Italianate residence offers 4413 square feet of thoughtfully designed living, complemented by extensive enhancements throughout. A double-height foyer creates a striking introduction to the home. Just off the entry, a formal living room framed by arched windows offers a refined space well suited for an office, library, or sitting room. Beyond the foyer, the layout opens to the dining area, expansive family room, and gourmet kitchen, where the home’s open-concept design is tailored for both everyday living and elevated entertaining. The gourmet kitchen is appointed with a large center island, a 6-burner Wolf range, abundant cabinetry, and generous prep space. Recessed lighting and expansive windows bring in natural light, while oversized pocket doors extend the interior living spaces effortlessly to the outdoors. Designed as a true extension of the home, the backyard features thoughtfully executed improvements totaling more than $700,000—creating a private resort-like setting. Complete with a pool and spa, covered outdoor living area, multiple gathering spaces, and curated landscaping, the outdoor environment is both functional and visually striking. The home features five en-suite bedrooms, including a desirable main-level suite. Upstairs, the primary suite offers a spacious retreat with a sitting area and a well-appointed bath featuring a freestanding soaking tub and separate walk-in shower. Secondary bedrooms each include en-suite baths, with one offering a private balcony, while a second-level loft provides additional flexible living space. Additional features include built-in audio in the living room, an upper-level laundry room with cabinetry and sink, paid-off solar, and an upgraded driveway. Residents of Altair enjoy access to resort-style amenities including pools and spas, clubhouse, tennis and multi-sport courts, parks, and scenic walking trails, all within a secure, guard-gated setting. Ideally located near premier shopping, dining, and major transportation routes, and within the Irvine Unified School District.
