Arctic TreeHouse Hotel opened in November 2016, on a steep, forested slope just outside Rovaniemi, Finnish Lapland's capital. The original concept was thirty-two paired units, raised on slender black legs to minimize disturbance to the hillside itself, shingle-clad and low to the ground in a way locals nicknamed "pine cone cows" before the name stuck. Five larger GlassHouses and three newer ArcticScene Executive Suites, added in 2019 with private saunas and soaking tubs, have since rounded the property out to roughly sixty rooms total.

Every unit shares the same defining feature: a glazed end wall positioned at the foot of the bed, angled toward the forest and the sky rather than toward a neighboring building. That orientation wasn't incidental. Studio Puisto specifically planned the placement of each cabin, and the lighting scheme across the entire property, to maximize the odds of an unobstructed aurora view — soft, minimal exterior lighting, a full decade before "dark sky hospitality" became an industry phrase anyone used.

The main building is shaped like a five-pointed snowflake, anchored by a lobby with a large steel fireplace and Rakas, the property's restaurant, where local cuisine shows up on a menu. Green roofs, local timber, and solar panels powering the main building round out a property that treats sustainability as structural rather than promotional.
