Description
Welcome to a truly exceptional offering, where no detail has been overlooked, and every inch exudes luxury, function, and style. This custom new construction home, paired with a beautifully finished accessory cottage, delivers an unparalleled living experience. Anchored by a grand two-story entry, the home immediately impresses with breathtaking floor-to-ceiling box molding, a sweeping oak staircase with wrought iron railings, and a black statement chandelier that sets the tone for the entire home. The formal living room features a gas fireplace framed in granite, soaring floor-to-ceiling windows, and gleaming 4” select-grade white oak floors that flow seamlessly through the first and second floors—including all bedrooms and hallways. The heart of the home is an incredible open-concept kitchen showcasing a huge two-tone center island, quartz countertops, white upper cabinets and rich brown lowers, all accented by a tile backsplash, pot filler, and Cafe Series stainless steel appliances including a built-in drawer microwave and oven. A full wall of sliding glass doors opens from the center to reveal a grand Trex staircase that cascades into a resort-style backyard, fully landscaped with a programmable sprinkler system. The first-floor laundry closet is both practical and stylish with a butcher block folding station, white cabinetry, and subway tile backsplash. A sleek first-floor powder room with matte black fixtures is conveniently located near a separate side entrance. Upstairs, the enormous primary suite offers a luxurious walk-in closet with custom built-ins and jamb switch lighting, and a spa-like bath with a double vanity and a walk-in glass stand-up shower. Additional second-floor bedrooms are all generously sized and feature upgraded moldings and finishes throughout. The hallway bath includes a Kohler soaking tub, porcelain tile, designer vanity, and quiet exhaust fan with push timer. The finished accessory cottage is a true bonus—perfect as a home office or studio—with new roofing, siding, windows, flooring, a half bath, and its own hot water heater. Structurally, the home features two blacktop driveways with cobblestone border and skirt, cedar impression siding on all exterior walls, a fully sheet rocked garage with 12’ ceilings and a floor to ceiling window, and a basement with outside entrance and dual egress windows. Every modern convenience is here—smart entry locks, built-in closet systems, TV and Cat 6 wiring in every bedroom, and high-efficiency Bosch HVAC and water systems across two zones—all tied into sewer and supported by new gas and water lines. This is a home where grand design meets thoughtful function, delivering the ultimate in new construction living.
