3558 Siembre St Step into a custom Mid-Century Modern gem in Bonita where sunlight pours through panoramic windows and the open great room/kitchen layout makes everyday living feel easy and connected. Thoughtful recent updates bring a designer touch-fresh, neutral finishes that enhance the home's mid-century character rather than replace it. You'll find three comfortable bedrooms plus a flexible optional fourth space that works beautifully as a guest suite, office, gym, or multi-gen room. The kitchen and baths have been refreshed with quartz counters, a generous island, stainless appliances, and plenty of storage-ready for casual meals or entertaining. Multiple living areas give you options for movie nights, homework zones, creative space, or a cozy reading corner, all leading naturally outdoors. The backyard is built for California living: an outdoor Thermador cooktop and grill, places to dine and unwind, mature trees, low-maintenance hardscape, and a turf area for play. A gated extended side yard adds even more flexibility, with the potential to reconfigure for extra off-street parking for a boat, trailer, or RV. All of this in one of Bonita's most sought-after pockets close to parks, trails, schools, and freeway access. Opportunity for buyers seeking flexibility today and options tomorrow-ideal for multi-gen living, work-from-home, and entertaining. Convenient to parks, trails, schools, and freeway access, and positioned near neighboring properties for those exploring a "compound" concept.
