24335 Arcadia Street A one-of-a-kind custom pool home estate sitting on nearly an acre in the heart of Santa Clarita's coveted Happy Valley neighborhood, with a 1-bed, 1-bath detached guest house. This extensively refreshed property offers exceptional space, privacy, and multigenerational versatility. Featuring a roughly 6, 084-square-foot main residence with 6 bedrooms and 5.5 bathrooms, a detached guest house with dedicated covered parking, a 3-car garage, and resort-style grounds, this home has been thoughtfully transformed since its previous sale. Extensive cosmetic updates throughout- from luxury quartz countertops to upscale hardware & plumbing fixtures, window treatments, and more- create a more polished, upscale feel while still retaining the elegance and craftsmanship of this custom home's features. Designed for both everyday living and large-scale entertaining, the main residence includes formal living and dining rooms, a spacious family room, and a generously sized kitchen equipped with a Viking range, double ovens, a built-in Sub-Zero refrigerator, new commercial-grade faucets, and abundant storage. Four secondary bedrooms and three bathrooms are grouped within the lower wing, while the expansive primary suite offers a private library and office, an additional flex or fitness room, and a deck overlooking the property. Just off the kitchen is the expansive laundry room, with extensive built-in cabinetry, plus a guest/maid full bathroom and living quarters. The outdoor setting is equally impressive. A private pool and spa create a resort-like centerpiece, surrounded by mature landscaping and an established orchard featuring a variety of fruit trees. Newly added raised garden beds expand the property's growing potential, creating a special environment for gardening, gathering, and enjoying the outdoors. Near the orchard, the detached guest house includes its own full kitchen, bathroom, and walk-in closet, ideal for extended family, long-term guests, a private workspace, or independent living accommodations. A solar system with Tesla battery backup adds valuable energy efficiency and resilience. With its remarkable scale, flexible floor plan, separate guest quarters, mature grounds, and extensive cosmetic updates, this Happy Valley estate offers a rare opportunity to enjoy the character of an established custom home with an entirely refreshed look and feel.
