An exceptional opportunity to own a luxury new construction home designed around your vision. Currently under construction and nearing completion, this one-of-a-kind residence offers the rare ability to personalize finishes, modify select layouts, and incorporate custom upgrades before move-in. Because the builder is also the seller, you'll enjoy an unparalleled level of flexibility rarely found in new construction. Set on a private 1.3-acre homesite surrounded by mature trees and approximately 25 acres of township conservation land, this spectacular 4,670-square-foot home offers the perfect blend of luxury, craftsmanship, and privacy. The striking exterior showcases timeless Hardie Board siding, cultured stone accents, black Andersen windows throughout, a standing seam metal porch roof, and an expansive covered front porch that creates exceptional curb appeal. Designed for both everyday living and effortless entertaining, the main level features a dedicated dining room, living room or private office, elegant powder room, and a luxurious first-floor primary suite. At the heart of the home, soaring 27-foot cathedral ceilings in the great room and kitchen create an unforgettable first impression, while walls of windows flood the space with natural light. A dramatic cultured stone fireplace anchors the open-concept living area, seamlessly connecting to the beautifully appointed kitchen. The gourmet kitchen offers custom Fabuwood cabinetry, quartz countertops, a spacious walk-in pantry, and a 48-inch Thermador propane range. Designed with both luxury and functionality in mind, the layout can accommodate one or two oversized islands, while premium appliance upgrades, including Thermador or Sub-Zero options, allow the space to be personalized to your vision. The first-floor primary suite serves as a private retreat, featuring 9-foot ceilings, a spa-inspired ensuite bath with heated tile floors, dual vanities with quartz countertops, and an oversized walk-in glass shower with dual shower heads. A separate walk-through wardrobe - ideal for a "his" closet or additional shoe and accessory storage - leads into the expansive customizable main walk-in closet. From there, enjoy direct access to the laundry room for exceptional everyday convenience, while a second entrance from the hallway provides added functionality. The second level is divided into two private wings. Above the primary suite are three generously sized bedrooms and two full bathrooms connected by an open hallway overlooking the great room. On the opposite side of the home, above the three-car garage, an expansive loft with soaring 11.5-foot ceilings and its own full bath can serve as a fifth bedroom, guest suite, in-law quarters, home office, fitness studio, media room, or playroom. The approximately 2,000-square-foot basement offers exceptional expansion potential, with options to finish the space with a fireplace, bathroom, bar, gym, sauna, wine room, theater, or other custom features. Additional highlights include light wide-plank hardwood flooring, a three-zone HVAC system, fully insulated interior walls for enhanced comfort and sound reduction, and the builder's renowned Forever Dry Basement waterproofing system. Outdoor living can be customized with optional additions including a rear deck, landscape lighting, and expanded front driveway parking. Located within the award-winning Great Valley School District, this is a rare opportunity to create a truly custom luxury home in one of Malvern's most desirable settings.
