Set on just over an acre in Frontenac's coveted Radcliffe subdivision, this stately 4,724 square foot residence with a side-entry four-car garage and fully finished lower level sits within the acclaimed Ladue School District. The current owners took the original structure down to the ground and built entirely new in 2019, delivering the scale, systems, and finish level only true new construction can offer. A circular drive winds past mature trees and manicured gardens to a columned portico and covered front porch. Step through the double entry doors into a light-filled foyer crowned by a coffered ceiling and crystal chandelier, with 10 foot ceilings, 8 foot doors, and engineered hardwood flooring throughout the main level. The great room is a showpiece beneath a coffered ceiling, anchored by a striking black fireplace with custom mantel and a wall of black-framed windows overlooking the grounds. The kitchen is a chef's dream. An expansive center island with seating and prep sink sits beneath ornate pendant fixtures, surrounded by custom white shaker cabinetry, gold-toned hardware, and quartz countertops. Sub-Zero refrigeration and Wolf appliances anchor a fully integrated package with double ovens, induction and electric cooktops, range hood, microwave, and ice maker, and a walk-in pantry keeps everything within reach. Open to the kitchen, the hearth room is where everyone will gravitate. Soaring vaulted ceilings with exposed beams, a floor-to-ceiling stone fireplace flanked by custom built-ins, and walls of windows make it equal parts dramatic and comfortable. It is the ideal spot for morning coffee, casual dinners, and everything in between. The formal dining room sits at the front of the home with crown molding and a crystal chandelier, while a dedicated wet bar with dark cabinetry, undermount sink, and beverage refrigerator connects it to the kitchen, making entertaining effortless. A private main-floor primary suite occupies its own wing, featuring plush carpeting, a tray ceiling with crystal chandelier, an inset fireplace, and room for a seating area overlooking the backyard oasis. The spa-inspired primary bath is a genuine retreat with heated floors, a freestanding soaking tub beneath its own chandelier, an oversized glass-enclosed steam shower with marble bench, dual vanities, and two custom walk-in closets. Main level laundry is handled in style with a utility sink and custom cabinetry, and a mudroom off the garage with built-in lockers keeps the daily coming and going organized. Upstairs, a spacious second living room makes a natural landing spot for homework, movie nights, or simply giving everyone room to spread out. Three generously sized bedrooms, each with plush carpeting, a private ensuite, and a walk-in closet, provide an arrangement families and guests alike will appreciate. The finished lower level extends the living space dramatically. A recreation room with polished concrete floors offers dedicated zones for lounging, media, and a ping pong table, served by a custom wet bar with black cabinetry, mirrored backsplash detailing, built-in sink, and refrigeration. A carpeted office with egress window sits just off the main gathering area, finished with a built-in window bench and gold-toned chandelier, functioning equally well as a fifth bedroom or guest suite. A full bathroom, dedicated home gym, sauna, and extensive storage complete the level. The backyard oasis boasts a heated gunite pool with integrated steps, sun shelf, and patterned tile border, paired with a spa and stone-clad fire bowls for cool evenings. The oversized covered patio is finished like an interior room, with a coffered ceiling, shiplap detailing, dual ceiling fans, recessed lighting, a mounted television with integrated sound, and space for both full outdoor dining and lounge seating. All of this sits minutes from Plaza Frontenac, downtown Clayton, and Highway 40.
