Ideally situated in the sought-after Westchester Crossing community of Roswell, 4165 Westchester Crossing NE is a rare find that perfectly balances traditional elegance with modern, multi-generational functionality. This meticulously maintained 5-bedroom, 3.5-bathroom residence sits on a .38-acre lot within the award-winning East Cobb school district. The main level is defined by smooth ceilings, gleaming hardwoods, and a chef's kitchen featuring granite countertops and gas cooking that flows into an oversized family room with custom built-ins. Upstairs, the vaulted primary suite offers a spa-like retreat, with a deep soaking tub and separate walk-in shower. The property's standout feature is the expansive, daylight-finished terrace level. Clad in large slate tile, this space functions as a true in-law or guest suite, complete with a full bedroom, bathroom, private "school room" or office, and a separate exterior entrance. Outdoor living is a priority here; enjoy morning coffee on the screened-in porch or host evening gatherings by the custom stone firepit within the professionally landscaped, picket-fenced backyard. Recent high-ticket upgrades provide peace of mind, including a newer water heater, serviced HVAC systems, and energy-efficient windows. Residents enjoy world-class amenities through an active HOA, including a swim team, tennis and pickleball courts, a clubhouse, basketball, and a playground, all just minutes from the heart of Roswell.
