Jeujura Treehouse Building SetUsing the same century old practices that founded the family owned business, the Jeujura Treehouse Building Set is built for generations of play. The 90 piece model builds a wooden hideaway in an ancient tree, complete with a swing, ladder, and pet cat. Made from beech and maritime pine from French forests and processed in French sawmills, their pieces are colored with water based tints and come in recycled cardboard boxes.
