High in the Seven Mountains and overlooking the city of Bergen, Norway, is a glass and wood cabin nestled in rocks and trees. It is 150 square feet and square in design, but its modern shape doesn”t take away from its naturalistic touches, like the burnt larch exterior. It also hides something that will make you do a bit of a double-take.

The cabin

Wait, what?

Imagine coming across this in the middle of a hike. This black hole-like entranceway seems to swirl before your eyes, and might remind you of certain elements of Cabin in the Woods. Fear not, for it just opens up into a cozy little home.

The cabin is called the “Tubakuba,” and gets its name from the tuba-shaped entranceway.

“Tubakuba” was designed by Norway”s Bergen School of Architecture in a workshop. The unusual doorway was inspired not only by the shape of a tuba, but also by the sense of wonder when one enters a cave or other mysterious place. The entranceway is child-sized; most adults have to crouch to get through it.

The tunnel-like entrance also doubles as a shelter, providing people with a place to be outside even if the weather is inclement.

“Tubakuba” has no electricity, but a stove will keep people warm during colder months.

The inside is spacious and sleekly modern. The cabin looks off the mountain, offering an incredible view of the city below. The cabin was designed as an “off-grid hotel room,” and can be rented for free for a day. If you don”t mind the low-ceilinged and slightly creepy entrance, consider “Tubakuba” when booking your next woodlands getaway.

So if the classically rustic look isn”t for you, consider making a trek to Norway, and enter this strange but cozy portal.
