Today’s Solutions: December 18, 2025

To call it a tree house would be almost insulting to Sweden’s Treehotel. The Lapland lodging opened its doors—or, rather, dropped its ladders—in 2010. Since then, thousands of guests have taken in the Lule River valley views from its treetop windows. The Treehotel has five different rooms; one resembles a bird’s nest, another a UFO. But staff says the Mirrorcube, designed by Swedish architectural firm Tham & Videgård, is by far the most popular choice. 

The Mirrorcube is covered in reflective glass, so it blends into its forest surroundings. This is ­luxury ­nature tourism: Inside the shiny box, you’ll find a ­living room with a double bed and bathroom. The ­hotel’s ­sauna is nearby. And if you covet a cube of your own, good news: A do-it-yourself version recently went on the market. It would definitely brighten up the ­backyard. | Find out more: treehotel.se
