Tucked away on a quiet cul-de-sac, this private estate offers a rare opportunity to own a true sanctuary in the heart of Sterling 20165 yet without the restrictions of an HOA. This completely custom colonial boasts over 4,800 finished square feet, a 2-car attached garage, plus a 4-car detached garage and workshop, sparkling in-ground pool, space for your RV, plus a BRAND NEW ROOF! (May 2025) From the moment you enter the sun-drenched 2-story foyer, you'll notice the thoughtful upgrades and custom details throughout making this ONE OF A KIND home comfortable yet unique. The main level features an open floorplan with gorgeous sand-in-place hardwood floors, oversized dining room with Valley Forge custom chandelier, a charming double-sided stone fireplace anchoring the expanded family room, powder room with batten board SS topped vanity, and ship-lap home office with gas fireplace. The spacious kitchen is bright and inviting, with white cabinetry, granite countertops, custom island with stainless steel top, glass-front upper cabinets, and a sunny breakfast room that opens directly to the fenced pool area. Up the elegant wood staircase you will find 3 full bathrooms UP, and four spacious bedrooms--including an expanded bedroom 2 with an en-suite bath above the garage and an equestrian-themed bedroom with custom barn door overlook adding character and charm. The primary suite is a peaceful retreat with tray ceiling and view of the pool plus an attached en-suite with separate shower, slipper tub, dual sink vanity topped with stainless steel, and ceramic tile floors. At the end of the hardwood-clad upper hallway lies the convenient upper level laundry room with sink connection. The fully finished lower level offers a flexible layout with a large rec room, theater area, 5th bedroom or 2nd office with hand-milled cabinetry and closet, a full bath with tub shower and ceramic tile, utility/storage room, and two separate walk-up double door exits to the beautifully serene fenced backyard. The detached 4-car garage and workshop, with ample windows and its own dedicated electrical panel, presents endless possibilities-- a gym, studio, tinkering on cars, or a work area for serious hobbyists. Behind it, there's space to park your RV with dedicated power. Mature landscaping, lush greenery, swingset, and a picturesque Beech tree grace the front yard, creating a truly idyllic setting--just minutes from top-rated schools, shopping, dining, and commuter routes.
