Underground House by Polish Architecture Firm

As curious as it is cool, the underground design for OUTrial House by Polish architecture firm KWK Promes reveals a secret in this quiet country field in Ksiazenice, Poland. Carved into the earth and concealed beneath a lush layer of grass, this innovative hideaway house peeks through only with a sliver of windows. An underground atrium was created by slicing into the design, opening it up to the sky while remaining “underground.” But perhaps most interesting feature about this unique design is that the landscaped roof is only accessible from inside the house, by ascending the grass-covered stairs. Beneath the camouflaged facade, the house boasts all the traditional goods: living rooms, functional spaces, and even a sound studio.
