A wooden treehouse is a structure erected in or on the limbs of a tree and made entirely of wood or other organic materials.
Common uses include a space for children to play, relaxation for adults, and pleasant outdoor entertaining. A typical wooden treehouse will include a platform, walls, roof, and entrance, as well as windows, shutters, railings, and a ladder or stairs for getting in and out.
Safety is of paramount importance in the design and building of a wooden treehouse, which is why it must be securely fastened to the tree and built to withstand the elements.
