Wall Saver is a line of decorative articles of urban furniture thought to preserve and at the same time to furnish the external walls of the houses. Wall Saver appears as semi-transparent tray containing repellent liquid for animals, easy to place and easy to remove, with the double function to decorate the external walls of a house and to put off the most common domestic animals to piss near these walls. So, Wall Saver is a clever solution which combines the instrumental function of the object to an aesthetic decorative function. The basic idea is to reproduce as industrial furniture object the concept of the plastic bottle common used to put off domestic animals to piss near gates or walls.
