Timeless architecture meets refined modern comfort, offering the scale, elegance, and versatility today's luxury buyers seek. A grand double-door entry opens to a soaring marble foyer, setting the tone for the sophistication throughout. The two-story great room takes center stage, wrapped in floor-to-ceiling windows and anchored by a magnificent two-story fireplace, with rich hardwood flooring tying the level together. The formal dining room flows into a chef-inspired kitchen featuring stainless steel appliances, dual ovens, granite countertops, and an oversized center island with cooktop. French doors lead to a sprawling rear patio - ideal for al fresco dining, summer entertaining, or unwinding beneath the evening sky. The main-level primary suite is a true sanctuary, complete with a tray ceiling, a wall of windows overlooking the grounds, and a custom walk-in closet. The spa-inspired ensuite features dual vanities, a jetted soaking tub, and a beautifully tiled walk-in shower. Additional bedrooms are equally spacious and sun-filled. The fully finished lower level is built for entertaining, featuring a private cinema room with tiered seating, a massive projection screen, and immersive surround sound, plus a dedicated game area and a spacious exercise room. Adding exceptional rental and income potential, this level also includes two additional bedrooms, a full modern bath, a second kitchen with stainless steel appliances, a brand-new washer and dryer, and its own separate walkout entrance - perfectly suited for multi-generational living, extended guests, or a private income-producing suite.
