3 Ada Lane — Setauket, NY 11733
Three Ada Lane is the kind of Setauket colonial that earns every dollar of its price. Custom-built in 1995 on nearly three-quarters of an acre, it sits in one of the North Shore’s most established neighborhoods — mature privacy plantings, refined curb appeal, and the quiet that only comes with a well-chosen street. Inside, the layout is thoughtful rather than just large: nine rooms, hardwood floors throughout, custom crown moulding, a gas fireplace in the great room, and a primary suite that functions as an actual retreat — radiant heated floors, updated bath, generous closet space.
The outdoor package is the other half of the story. A Gunite pool with overflow spa, a recently updated Trex deck with a dedicated gas line for barbeque, and a full privacy-landscaped yard. The pool carries a new Loop-Loc cover. The basement has an outside entrance — usable as additional living, a recreation room, or storage — and the 2-car garage completes a package that sold above list at $1,350,000 in 42 days. This profile compiles the verified property data, school district details, and neighborhood context for the record.

School District
Three Village consistently ranks among the top public school districts on Long Island and in New York State. Ward Melville Senior High School in particular draws buyers specifically for its academic reputation — strong AP enrollment, competitive arts programs, and a track record that carries weight with college admissions. For families, this district is a genuine asset.
The Neighborhood
Stony Brook University
Stony Brook University and Stony Brook University Hospital are minutes away — a meaningful anchor for the local economy and a steady source of demand for homes in this price range. Proximity to a major research institution shapes the entire community’s character.
Port Jefferson Village
Port Jefferson’s harbor, restaurants, boutiques, and ferry to Bridgeport, Connecticut are a short drive. It’s the kind of waterfront village that makes weekends feel like a different life — without requiring a second home to access it.
North Shore Beaches
Long Island Sound beaches — calmer water, less traffic, genuinely underrated — are accessible throughout the warmer months. Setauket Harbor and the surrounding Frank Melville Memorial Park system give the area a preserved, open quality that newer North Shore suburbs can’t replicate.
LIRR Access
The Port Jefferson branch of the LIRR puts Penn Station within reach for commuters, and the Ronkonkoma branch offers an express option nearby. For buyers who need the city without wanting to live in it, this location delivers a real commute — not a theoretical one.
What Made This Home Stand Out
Sold Above List — Cash — 42 Days
This home closed at $1,350,000 on a $1,299,900 ask — 104% of list — in a cash transaction that closed in 42 days. That outcome doesn’t happen by accident. It reflects accurate pricing, a market that recognized the value, and a property condition that didn’t invite negotiation downward.
Gunite Pool + Overflow Spa on 0.69 Acres
A Gunite pool with overflow spa and new Loop-Loc cover, set on nearly three-quarters of an acre with full privacy landscaping and a gas-line Trex deck. This is an outdoor living package — not an amenity tacked on. In the Three Village market, homes with this combination at this price point move quickly.
Primary Suite With Radiant Heat
The fully updated primary suite with radiant heated floors sets this home apart from comparable colonials in the area. Radiant heat is a genuine comfort upgrade — not a cosmetic one — and in a bedroom context, it’s the kind of detail that buyers who’ve lived with it won’t voluntarily give up.
Full Basement With Outside Entrance
A full basement with a separate exterior entrance is a functional asset in ways a standard basement isn’t — it reads as flex space, in-law potential, home office, or recreation room without requiring interior access. In a 3,403 sq ft home that doesn’t show its footprint on paper, this is where the real square footage story lives.
Ward Melville High School District
Three Village Central School District — and Ward Melville specifically — is one of the primary reasons buyers pay a premium for Setauket addresses. It’s not abstract reputation. It’s AP course offerings, college placement data, and the kind of program depth that smaller districts simply can’t sustain. For families with school-age children, the district boundary is a hard filter.
