Looking for a four bedroom single family home in Downingtown, PA, with over an acre, no HOA, a private backyard, and convenient access to Exton and West Chester? Welcome to 4009 Katie Lane, a beautifully maintained and move in ready Colonial tucked away on a quiet cul de sac in the established Trestle Woods and Deer Crossing neighborhood of Chester County. A new roof and gutters, a brand new composite deck, and a radon mitigation system add to the home’s appeal. From the moment you step inside, it is easy to begin imagining life here. Hardwood flooring carries throughout the first floor, while natural light and an open layout create an inviting flow for everyday living. The formal living and dining rooms provide flexible spaces for hosting holidays, working from home, enjoying a quiet conversation, or gathering with the people who matter most. White cabinetry, granite countertops, a tile backsplash, stainless steel appliances, a large pantry, and a spacious island make the kitchen a natural gathering place for morning coffee, weeknight dinners, and conversations that continue long after the meal is finished. The kitchen opens directly to the family room, where a gas fireplace adds warmth and creates a comfortable place to unwind. First floor laundry makes everyday routines easier. Outside, the brand new composite deck invites you to enjoy outdoor dining, weekend gatherings with the amazing neighbors, and quiet mornings overlooking the private backyard. Picture summer dinners outdoors, a garden taking shape, or a peaceful evening with room to spread out on more than an acre of your own space. The fenced in space makes it perfect for Fido. Upstairs, the spacious primary bedroom provides a comfortable retreat with a walk in closet and a generously sized bathroom featuring a separate shower and soaking tub. Three additional bedrooms offer ample closet space and flexibility for guests, hobbies, or home offices as your needs evolve. The setting feels removed from the rush of everyday life, yet the location keeps everything within easy reach. Route 30 Business is 0.5 mile away, Route 322 is 1.6 miles, and Route 113 is 2.3 miles away, with convenient connections to the Route 30 Bypass and Route 82. Downingtown Train Station is 1.3 miles from home, and Thorndale Train Station is 2.2 miles away via Hazelwood Avenue, providing two nearby options for SEPTA’s Paoli/Thorndale Regional Rail Line, formerly known as the R5, with service to Center City Philadelphia. Enjoy Downingtown Borough’s restaurants and shops, visit Kerr Park just 2.2 miles from home, or head to the Struble Trail, 2.4 miles away. Main Street at Exton is 6.3 miles away, while West Chester’s shopping and dining are also within easy reach. Driving distances vary by route and destination. Public water, public sewer, a two car garage, new deck, new roof and gutters, radon system, fenced yard, and no HOA add everyday convenience. With its recent improvements, private outdoor space, welcoming neighborhood setting, and access to so much of what makes Chester County special, 4009 Katie Lane offers room to settle in and make yourself at home. Schedule your tour and experience the setting for yourself.
