House of the Week: A 1914 Shelter Island Estate With a Private Dock Lists for $15.995 Million

Let’s talk about Shelter Island — the kind of place you go to get away, not to show off. Over on Harbor Lane sits a century-old estate with a wild proposition: buy the historic house, pool, private dock, and, if you feel like it, scoop up three extra acres next door and build out your own compound. We’re not talking your average waterfront home. This is the sort of place you could stretch into nearly five acres, turning that summer retreat into an all-out empire.

The bones of the estate go way back. Built in 1914 by Samuel Hird, passed down to cosmetics king Bob Ruttenberg, it’s now up for grabs at $15.995 million. That’s for 1.5 acres and a sprawling 4,500-square-foot home overlooking Dering Harbor. From here, you get about 245 feet of shoreline, plus a little parcel with its own dock with sunset views, porch living, and water so close you can hear it.

Whoever grabs this place gets first dibs on the neighboring land. Want more elbow room? Tack on an extra $2 million, snag the three acres, and go wild with plans: a guest house, tennis court, outrageous gardens, you name it. The additional space is ready for someone with vision.

On its own, the house is already a classic summer hideaway. The grounds are lush enough for privacy, the heated pool and spa call for lazy afternoons, and there’s even a pool cabana and three-car garage, both with old-world charm. Sure, the next owner might want to freshen things up, but the bones are solid.

Step inside and you can feel that early-20th-century grandeur. There are oversized windows and French doors that frame the harbor, and wood-burning fireplaces keep things cozy when it turns brisk. Living and dining rooms are built for gatherings, the kitchen is big enough for catering, and there’s a butler’s pantry. Seven bedrooms mean the doors are open to friends, family, and whoever else stumbles in for the weekend.

What makes this property different isn’t just the architecture or history, but the ambition baked into its listing. You can’t replicate a view like this or a hundred-year-old porch. The luxury here is getting to decide, without limits, just how big your Shelter Island dream goes.

And Shelter Island itself? It’s got a quieter soul than the Hamptons. Less flash, more hush, more boats than Bentleys, and a vibe that feels genuinely apart from the mainland. Life here centers around the water and the simple pleasure of pulling up to your dock after a jaunt across the harbor.

So, for just under $16 million, you land the house, the grounds, the dock, and the history. If you spring for $18 million, your legacy gets a little larger. Either way, you’re buying into Shelter Island’s quieter side and the chance to own history, with room to build whatever comes next.
