This lovely "tree house" colonial sits comfortably nestled in an idyllic natural oasis in one of Vienna's most sought-after communities. Though only minutes from Reston Towne Center, Tysons Corner, and downtown Vienna, you are on a quiet cul de sac, in an oasis of green space, literally surrounded by 50+ acres of public forest and parks, with walking trails, streams, and easy access to the W&OD bike path. Sip your morning coffee on the tranquil screened porch, as you watch the deer and foxes wend their way through your backyard in search of breakfast. Take your daily walk by going through your backyard to the trails and walk for literally miles, your only companions the wildlife. And end your evening with a glass of your favorite vintage in the hot tub on the deck, as the crickets serenade you in total privacy. Updated to absolute perfection, this brick front colonial with handsome blue stone walkway offers almost 5,000 square feet of light filled and practical space on .57 acres. The sprawling main level is floored in gleaming hardwood. It features formal living and dining rooms with ample natural light and elegant trim work. The dining room thoughtfully flows out both to the living room and to the screened porch, ideal for holiday dinners and large-scale entertaining. The stylish updated kitchen boasts cream cabinetry, granite counters, stainless steel appliances, and a bright breakfast room that flows seamlessly into the family room. The family room is highlighted by a white-washed brick fireplace and provides access to the rear deck and hot tub. A practical home office with a wall of built-ins sits off the foyer, overlooking the leafy front yard. A functional laundry/mudroom and a stylish powder room complete the main level. Upstairs, the expansive owner's retreat offers a large bedroom, two walk-in closets, and a spa-like ensuite with a separate glass-sheathed shower, free-standing soaking tub, and double vanity with a cabinet tower for ample storage. Three additional generous bedrooms share an updated full bath. The walkout lower level provides an enormous, full daylight recreation room with built-in shelving, perfect for game night and Sunday football with friends, along with a private fifth bedroom and bath for long-term guests. The lower level also includes a large unfinished storage room, which would be ideal for a future home gym. Outside, you have paradise ... an inviting deck with hot tub, a screened porch, and a lower-level patio, all enjoying tranquil views of the surrounding parkland.
