Tucked away at the end of a quiet cul-de-sac in the coveted Oakbrook community, this exceptional 4-bedroom, 2.5-bath Colonial offers a rare blend of privacy, serenity, and space-an increasingly hard-to-find retreat that feels worlds away, yet remains close to everything. Surrounded by mature trees and the gentle sound of a stream, the home's setting is truly its signature feature. Step onto the expansive two-tiered deck and experience your own private sanctuary-perfect for sunset evenings, morning coffee, or effortless entertaining against a picturesque natural backdrop. Inside, refined yet comfortable living unfolds with generous, light-filled spaces. Rich wood flooring flows through the oversized family room and elegant dining room with bay window, while a dedicated study with classic oak paneling, built-ins, and French doors offers a quiet, sophisticated workspace. The sunlit kitchen is designed for both everyday living and gathering, featuring a center island, cooktop, wall oven, and breakfast area-all perfectly positioned to capture peaceful views of the surrounding landscape. Upstairs, three spacious bedrooms and two full baths provide a restful retreat, with tranquil views continuing throughout. The walk-out lower level presents an exceptional opportunity to expand-ready to be transformed into additional living space tailored to your vision, whether a home theater, guest suite, fitness studio, or multi-generational retreat. With no HOA, unmatched privacy, and a location just minutes to shopping, dining, I-95, and Quantico, this home offers the perfect balance of seclusion and convenience.
