These blocks work both as a classic puzzle game with one solution when the pieces are laid down in their fine handmade wooden box, but can also be used to build cities that can house anything from Lego men to Barbie dolls. The pieces are wide and can stand so that you can easily build in height. Each piece has different cuts, which give the houses character and depth. They also decorate beautifully in the window shade or in the children's room. There are 7 houses in the box.
