About this home

Welcome to 5 Diane Court, a thoughtfully updated Colonial nestled on a quiet cul-de-sac with views and access to a private, tranquil lake. This 6-bedroom, 3 full bath home provides an exceptional lifestyle both inside and out. The heart of the home is the updated kitchen, featuring a Sub-Zero refrigerator, a Viking 6-burner stove, and sliding doors that open directly to a deck. The main level also includes a first floor bedroom and full bathroom, a living room with a fireplace, a formal sitting room, and a dining room with doors leading to a charming screened porch overlooking the lake beyond. Upstairs you’ll find a spacious primary suite with its own private bath, plus four secondary bedrooms that share a hall bathroom and a laundry room. The walkout lower level (not included in the square footage) expands your living space with a versatile recreation room, a thoughtfully designed mudroom with built-in closets, a pantry, utility room and direct access to the 2-car garage and whole home generator. Outdoors, enjoy your own herb and vegetable garden and beautifully maintained mature landscaping. The property includes shared lake access with neighboring homes. Part of the Katonah-Lewisboro School System. Minutes to major highways and the Katonah and Goldens Bridge train stations.
