Nestled on a peaceful, tree-lined street, this privately gated property offers the perfect blend of luxury, privacy, and natural beauty on a sprawling 31,798 sq ft lot with direct access to scenic bridle trails. From the moment you arrive, you're greeted by a tranquil front yard featuring a cascading waterfall, a serene Koi pond, and mature citrus trees-setting the tone for what lies ahead. Inside, the home offers over 5,000 square feet of thoughtfully designed living space that seamlessly combines modern sophistication with everyday comfort. Vaulted ceilings and expansive windows fill the home with warm, natural light.

There are four spacious bedrooms, including a luxurious primary suite with soaring ceilings, an oversized walk-in closet, a spa-like en suite bath, and a private flex space ideal for a home gym, office, or yoga studio. Doors from the suite open to a private balcony overlooking the show-stopping backyard-perfect for morning coffee or evening sunsets.
