We can't remember seeing a tree house we haven't liked. Even the one our dad built us in the 80's, it could only hold two kids at a time but we thought it was the best. Now, having grown up, our tastes have matured but our interests in tree houses have only grown stronger. Baumraum is a team of German based architects, landscape designers, tree experts and craftsmen who build individual houses based on the needs of each client. We love the simplistic design that makes us think that maybe we could construct one of these in our own backyard. Along with the reliability of a sturdy tree, many of these tree houses are held up by cables. However, if trees are not abundant in your yard, they can always be stabilized by a group of beams/stilts and secured to the ground.
