The primary residence offers generous living and entertaining space with an eat-in kitchen, formal dining room, living room with fireplace, first-floor office/bedroom and full bath. Upstairs are 3 additional bedrooms and 2 full baths, including a spacious primary suite. Additional recreation and storage space is available on the lower level and is not included in the 3,076 sq. ft. above-grade living area. Set on 1.27 acres in a desirable Wallingford location, the property borders approximately 11 acres of Wallingford Land Trust property, creating a peaceful natural backdrop while remaining convenient to area amenities and major routes. More than 20 documented improvements enhance the property, including a roof replaced approximately 3 years ago, professionally rebuilt chimney in 2026 with 10-year warranty, complete exterior restoration and repainting in 2026. Updated mechanicals throughout. Additional features include a 2-car garage, 16' x 12' shed, EV charging station, and expansive rear yard with mature landscaping. For those seeking true separate living quarters without sacrificing the space and layout of a traditional primary residence, 18 Quigley offers a configuration rarely found: 3,076 sq. ft. above grade, 5 bedrooms plus office/optional bedroom, 4 full baths, two kitchens and a legal 2-bedroom accessory apartment with substantial independence from the primary residence.
