These are wonderful German Cardboard buildings made from recycled and recyclable cardboard they are light, easy to assemble and easy to store.  The plain cardboard lets your children colour and decorate them however you like.  Why not stick real straw on the thatched roof of the farm or add tissue paper leaves to the treehouse?  Your imagination is the limit. 

The medium sized buildings come with a set of 12 felt tip pens to start the decorating but of course that is just the start!
