To provide an artificial garden so designed as to have undulation, freely set its outer configuration, and make it possible to transfer members for structuring the garden through the inside of a house while saving labors, costs and time each required for construction.

This artificial garden is formed by arranging a lot of garden structure boxes filled with planting soil so as to be adjacent to an artificial garden construction surface. The garden structure box has the following structure: the side frame of each of the boxes is shaped along a virtual partition obtained by dividing the artificial garden to be formed into nearly lattice shapes with desired patterns. The upper end of the side frame is formed so as to be along the undulation of the planting surface of the corresponding virtual partition.
