About This Home
Rare luxury new construction in Webster Groves offering exceptional design, high-end finishes, and nearly half an acre of deep backyard space — an opportunity seldom found in this established community. The main level showcases beautiful white oak hardwood flooring throughout, a dedicated office, and a spacious open-concept layout designed for modern living. The gourmet kitchen features exquisite custom cabinetry, quartz countertops, large waterfall island, and seamless flow into the living area, creating an ideal setting for entertaining. A main-floor bedroom + accessible full bath provides flexibility for guests or multigenerational living, along with a main-floor laundry + mudroom — one of two thoughtfully placed laundry areas in the home. Upstairs, you’ll find four generously sized bedrooms including a luxurious primary suite. Equipped with a soaking tub, a spacious spa like shower with a bench and double rain heads, custom white oak vanities with a makeup area between, and a custom walk-in closet. As for the other bedrooms, two bedrooms share a Jack-and-Jill bathroom, while another offers its own private ensuite — all featuring custom closet shelving for exceptional organization. A spacious second-floor luxury laundry room adds everyday ease and efficiency. The finished lower level provides an expansive open rec room complete with a wet bar and space for a beverage cooler, ideal for entertaining or additional living space. A bedroom and full bath offer excellent guest accommodations, while two oversized storage rooms provide incredible flexibility for a home gym, hobby space, or future expansion. Outside, the property offers a large covered patio, private attached two-car garage, large additional parking pad, and a rare deep backyard providing exceptional outdoor space not often found in newer construction. Located within the highly sought-after Webster Groves School District and walkable to Avery Elementary, parks, local dining, coffee shops, and retail, this home presents a truly rare opportunity to enjoy luxury new construction in Webster Groves.
