This fine home is the one you've been waiting for! Located just outside of vibrant Kennett Square, 121 Hadleys Mill Run is a fantastic 4 Bedroom, 3.2 Bath Colonial in Unionville Chadds Ford School District! The home is situated in the cul-de-sac neighborhood of Hadleys Mill, backs to open space and is a stones through away from Kennett Square Golf & Country Club. The handsome curb appeal of this home showcases the classic Hardie siding and turned garage with wood-look door. Step inside from the covered front porch, and be greeted by a spacious and sunlit foyer with expansive hardwood floors and tasteful décor. You'll immediately notice the attention to detail with the paneled, turned staircase and arched doorways. To the right, the expansive foyer opens to the Living Room with ample trimwork and oversized windows. Foyer also opens to the formal dining room with a continuation of upscale finishes. Ahead is the generously sized family room with (natural gas) fireplace and open to the Kitchen. The gleaming kitchen offers an expansive concrete-top island, custom backsplash, and roomy dining area. This floorplan was made for entertaining as Kitchen sliders provide seemless access to rear composite deck and private views of the wooded backdrop. Back inside, the first floor is rounded out by a large Laundry Room, nearby Powder Room, and a continuation of hardwood floors, attractive trimwork, and large windows. Upstairs there are 4 large bedrooms, including the generously sized Primary Bedroom with large en-suite bath and large en-suite Dressing Room (complete with the included 'island'. Primary bath includes oversized shower stall, separate soaking tub, and double vanity. The three additional bedrooms are all generously sized and are served by two additional baths. One benefit of the 4th bedrooms is the adjacent loft/ bonus room which easily serve as an in-law suite or aupair suite. Downstairs the finished, walk-out basement (complete with an additional powder room) offers flexibility for use as you see fit. Additionally, the current owners utilized one portion of the basement for an excercise area without foregoing plenty of storage space in the remaining unfinished portion of the basement. Finally, if the view from the Deck, wasn't enough, you'll find your own private oasis in the lower level screened porch with porch swing! Relax the evening away in this special space. The gently sloping yard provides complete privacy with mature trees and adjacent open space. Top it off with a gas-fired back up generator! Other notable features include the near new HVAC systems (2023 and 2024), newer roof (2018), and Public Water/Sewer! Schedule your tour today!
