This $3.7M New Hampshire Lake House Has a Tree House Inside — and It Was Built for $10 Million

When r/zillowgonewild posted this listing, the author led with "I want to be a child again!!" — and after one look at the indoor treehouse room suspended above a living tree, the sentiment is hard to argue with. This Adirondack stone and timber home on Merrymeeting Lake in New Durham, New Hampshire is one of the more genuinely singular properties to hit the market this year.

An Artist's Dream House, Now Available

Built in 2005 as the dream home of an artist who, by the listing's own account, spared no expense, the construction cost is estimated at $10 million — over $1 million of which went into masonry alone. The result is a 6,623-square-foot Adirondack-style home on the sandy shore of Merrymeeting Lake, one of New Hampshire's most prized spring-fed lakes, known for pristine, crystal-clear water. The great room announces the home's scale immediately: a three-story stone fireplace rising through 20-foot windows that open the interior to the surrounding forest and lake. Exposed beams, cathedral ceilings, custom cabinetry, and a chef's kitchen with a large island carry the craftsmanship throughout. There are four bedrooms, each with its own private bathroom, a separate in-law suite reached by a path called "The Forest Path," and enough stained glass, skylights, and handcrafted detail that the listing describes it, accurately, as an artistic masterpiece.

The Birdhouse — and Everything Else

The room everyone wants to know about is called "The Birdhouse" — a special room with a balcony that appears to be supported by a living tree growing beneath it. It is, by any reasonable measure, an indoor treehouse, and it is exactly as magical as it sounds. The Reddit poster who shared this listing summed it up plainly: "Whimsical house with a tree house inside. Feel like a child again." Beyond the Birdhouse, the property sits on nearly an acre of lakefront with 100 feet of sandy beach, a private dock, and a raft, abutting 86 acres of conservation land. The location is 90 minutes from Boston and at the intersection of New Hampshire's Lakes Region and its mountain country — close to hiking, skiing, snowmobiling, and the kind of lake life that justified building something this extraordinary in the first place. The current owners have spent three years repairing and improving every aspect of the property, and they've attached to the listing both a full list of updates and a document called "Common Feelings and Sentiments" — a guest record, essentially, of the emotional response this house tends to produce in people. The property has been featured in Boston Magazine and has an excellent weekly rental history. It is listed at $3,695,000.
