It’s called the Blue Cone, but the joke’s on the name. There’s nothing blue about it. Against the dark green of Swedish pines, it blazes red—like a misplaced berry or a Scandinavian exclamation mark. Locals still smirk at the contradiction. Visitors, meanwhile, just stand there a moment longer than they meant to, staring upward.

Unlike its flashier Treehotel siblings—the UFO, the Mirrorcube—the Blue Cone doesn’t try to shock. It’s humble, almost modest in form, and then—bam—there’s that color. Architect Thomas Sandell designed it to be approachable, not intimidating. A place you enter, not merely admire. And accessibility was never an afterthought; the entire structure is reachable by a gentle bridge that floats across the slope from a neighboring hill. No ladders. No acrobatics. Just a quiet, confident welcome.

Three sturdy foundations anchor the building to the forest floor. Technically it’s not hanging from trees at all—but you wouldn’t guess that from inside. The illusion is perfect: windows frame treetops instead of trunks, and the floor seems to hover. When the wind stirs, the pine scent seeps through the walls’ thin seams. You might think it’s in your head. It isn’t.

Step inside and the mood flips from bold to calm. Everything—walls, ceiling, floor—is dressed in pale birch. The light here feels filtered, softened by wood grain and snow glare. At 22 square metres, it’s compact but never cramped: one main room that spills into a loft, a tiny lounge, a snug bedroom, and a bathroom that somehow manages to smell faintly of cedar and cold air. Four guests fit comfortably, though two feel ideal.

Outside, the Lule River snakes silver through the valley. On clear mornings you can see mist rising straight from its surface, a slow-motion dance that the north does better than anywhere. Come winter, snow muffles everything. You hear your own heartbeat. Then—crack!—a branch drops ice somewhere nearby, and you’re back on Earth.

The rest of Treehotel spreads quietly through the forest: seven rooms, each more improbable than the next. Yet the Blue Cone keeps its own rhythm—simple, grounded, welcoming. It proves that not every treehouse needs to look like science fiction to feel magical.

Book a night, and you’ll see. Even walking across that bridge feels symbolic—leaving the ordinary slope of life for something balanced between earth and air. And despite its name, the Blue Cone glows warm red in the dusk, refusing, charmingly, to blend in.
