25 Park Street Welcome to 25 Park Street. Located at the very end of a quiet street with no through traffic, this impressive center-hall colonial in the Old Setauket Historic District has the space and layout that is hard to find right now. Walk in and the two-story foyer with a center-hall staircase and grand chandelier immediately sets the tone. The main level flows well: A formal parlor and dining room, a huge great room with a gas fireplace and high ceilings, and an updated kitchen with gas cooking and a center island. The kitchen opens to a bright breakfast area surrounded by windows-a perfect spot for morning coffee. A detail that matters for a lot of buyers: There is a first-floor room that works perfectly as a bedroom or office, with a powder room right outside the door - no stairs required. Upstairs, the primary suite is at one end of the house with its own en-suite bath with jetted tub, generous closets, and a separate office or dressing area. Right next to the primary is a bedroom with its own en-suite bath, and at the other end of the house are two more good-sized bedrooms, and a full hall bath. The lower level is a big bonus here. It is fully finished and permitted, with a separate outside entrance, a second kitchen, a full bathroom with stand-up shower and soaking tub, and plenty of room for a guest suite or a home office. The total finished space across all three floors is over 5, 150 square feet. Outside, the property sits on just under an acre of beautifully landscaped grounds with mature specimen plantings. The in-ground pool is surrounded by a large two-tier paver patio, and there is a built-in gas grill and fire pit. There's a Belgian-block driveway and an oversized three-car garage. Sprinklers and four-zone heat and AC are already in place. Located in the Three Village School District, close to Stony Brook University and the hospital, the LIRR, and the Village Green.
