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.
