The moment you drive through the gates and enter this 1.64 acre exclusive Pinnacle property, you know you've found something truly special and unique. Completely remodeled, this home with detached guest house boasts an East Coast meets West Coast vibe where absolutely everything has been thought of to provide the ultimate family home and entertaining space. The grand yet homely interior has over6000 sq ft of living space with game room, family room, 2 home offices, 5 ensuite bedrooms that include a lovely bright master with oversized balcony and oversized custom walk-in closet, a spacious bonus room upstairs, and a wonderful family kitchen with huge granite island and eat-in dining room, in addition to the formal dining and living rooms. Outside, make the most of the warm Californian climate and very private backyard with a beautiful pool and spa, Baja shelf, fountains, and built-in speakers. Keep active on your own sports court where you can challenge family and friends to a game of basketball, pickleball or volleyball. Watch the amazing sunsets while dining alfresco, using the outdoor kitchen, then spend the evening around the large gas fire pit. 5421 Castillo de Rosas is arguably The Pinnacle's nicest home, and sits on the neighborhood's largest lot.
