This spacious masterpiece of modern architecture is situated on a quiet, curving street in the desirable George Mason School district and offers privacy, proximity, luxury, and functionality on one of the nicest streets in Alexandria. The property is a 20-minute drive to the Capitol, 10 minutes to Old Town, and a short walk to the fun and excitement of Del Ray. The home takes full advantage of its location on .32 acres adjacent to Alexandria City's 6.25-acre Monticello Park. Monticello Park has been named a Community Forest by the Old-Growth Forest Network, a designation that protects the park from future development. Drawn by the stream, ample trees and green space, the park is a stop for more than 30 species of warblers on their annual spring migration, as well as orioles, finches, wrens, thrushes, flycatchers, and many more. In the home, the abundance of nature is highlighted by large windows that afford magnificent views. Appointed with high-end materials and cutting-edge design, the home has six bedrooms, including a main-level ensuite bedroom/office, and six and a half baths. The elegant, modern floating staircase with thick oak treads connects the three levels, giving the home an open, airy feel. The 9' ceilings throughout the home enhance the spacious ambiance. The heart of the home is the kitchen, with its oversized island, large pantry, top-of-the-line Thermador appliances, luxurious quartz countertops, and designer tray ceiling. Double sliding-glass doors lead to the private rear deck overlooking the park, making this a place where people will want to spend precious time together. Upstairs are four large ensuite bedrooms, including the primary bedroom which occupies the entire rear of the house, providing stunning park views through oversized casement windows. The primary bedroom is a luxurious escape from the day-to-day, with a beautiful designer tray ceiling, and a large walk-in closet (14'3'' x 13'3''). The luxurious primary bath features a floor-to-stone ceramic tile shower surround, custom double vanity, rain shower, body spray (seven shower heads in all), and a freestanding soaking tub. The sixth bedroom is located on the lower level with an adjacent ensuite bath and spectacular views of the park. The spectacular lower-level media room is prewired for projection and high-speed digital service and features custom lighting and a riser for two- seating. The lower level recreation room is the ideal place to entertain or just relax, with a walk-behind wet bar custom cabinetry, quartz countertops, a wine cooler, and an ice maker. A sliding glass door leads to a covered patio overlooking the park. The house is prewired for internet, including a video security system, and features three heating and two cooling zones. Unlike any home in the area, 3113 Circle Hill blends modern luxury with unparalleled proximity, making this property the perfect home for anyone drawn to luxurious living in Alexandria City among the birds and trees.
