Description

NEW 2026 BUILD! Welcome home to this luxury estate featuring 4 bedrooms plus an office, 2.5 baths, and a detached 2-bedroom, 1-bath guest house, all situated on an expansive third-of-an-acre lot designed to provide privacy between both residences. Built by McDew Development, this unique property offers luxury living, exceptional flexibility, and income-producing potential in one of St. Petersburg’s fastest-growing areas. The striking modern exterior showcases custom white stucco, dark architectural accents, and black impact-rated windows and doors. A welcoming front porch leads to an open-concept interior featuring soaring ceilings, luxury vinyl plank flooring, wide baseboards, recessed lighting, and designer finishes throughout. Expansive sliders open to a private, fully fenced backyard with ample room for a resort-style pool. At the heart of the home, the chef’s kitchen features a waterfall island, floor-to-ceiling two-tone wood cabinetry, quartz countertops, built-in cooktop, wall oven, wall microwave, counter-depth refrigerator, and a spacious walk-in pantry with additional storage and prep space. The first-floor primary suite offers custom walk-in closets and a spa-inspired bath with a soaking tub, oversized shower, floating double vanity, and private water closet. A dedicated office completes the main level. Upstairs, three additional bedrooms surround a spacious loft-style great room with a wet bar, ideal for entertaining or relaxing. Adding tremendous value is the detached 800 SF ADU, complete with 2 bedrooms, 1 bath, a full kitchen, living area, laundry, and private balcony. Whether used for rental income, multigenerational living, or extended guests, this fully self-contained residence provides versatility rarely found in new construction. The property is completed by an oversized 3-car garage with alley access and is conveniently located minutes from Downtown St. Petersburg, the St. Pete Pier, Gulfport, Tropicana Field, and I-275. Situated outside a flood zone and custom built in 2026, this is a rare opportunity to own a private modern luxury retreat with both lifestyle and investment appeal.
