Villa Julia is a house for children in which they are provided with the cardboard and the lines for folding, but the children themselves set it up (under adult supervision), find a place for it and make it their own by coloring the drawings found on the sides. They are given a plan with easy instructions for assembly, in five stages. The game takes place in several phases: assembly, personalization and decoration, occupation and dismounting. Villa Julia has a chimney, eaves, door and windows. Its lines make one think of typical middle-class detached North American homes of the 1950s.

Villa Julia is made of cardboard and is not colored. It comes complete with instructions and stickers for personalization.
