Welcome to a truly one-of-a-kind residence that blends historic charm with modern comfort. This home was thoughtfully converted in the early 1900s from a barn into a spacious home with 4,204 square feet of interior finished space. 2,739 sf on the top 2 floors, and a 1,465 sf finished in-law suite below with separate entrances that walk out to the driveway and side yard. This exceptional property offers a great combination of character, space, and almost limitless potential for customization. 24 Old Knollwood sits proudly on just under a 1/2 acre wooded lot, where the home’s unique stone facade stands out and creates instant curb appeal. Step inside through the foyer into a dramatic double-height living room with a matching height fireplace to create an entertaining space that can be both cozy and grand. With 5 generously sized bedrooms and 2 full bathrooms, there is flexibility for every lifestyle — from growing households to multi-generational living. The expansive layout continues outside, where a two-level deck overlooks a large backyard, perfect for entertaining, gardening, or quiet outdoor relaxation. Car enthusiasts and hobbyists will appreciate the detached and oversized 2-car garage, offering 576 sf and a loft for additional storage or workspace. This property’s mother-daughter suite on the lower level, an added 1,465 sf of space, also presents an excellent opportunity for extended family living, guest accommodations, or rental income. Full of character, space, and endless potential, this rare offering combines history and functionality in a suburban setting with every convenience nearby. A must-see home unlike any other.
