Neither a tiny house nor a treehouse, Arcadia the Spirit Shelter is a furnished backyard hangout for exploration and meditation. The Allergutendinge design can be assembled and reassembled in any place, allowing the users to define where or what Arcadia is for themselves. Furnished with a built-in bed, dining table, and storage, the little enclave is fine for a siesta or a half-day stay. The lightly decorated space is made of naturally finished wood and painted white on the outside. A skylight, a window, and a porch open up the space to the surrounding environment, connecting the spirits of the person, the shelter, and the surrounding paradise.
