Removing a strip of pavement along the facade of a building allows the rainwater from the facade to infiltrate into the ground. Climbing plants friendly to birds and butterflies increase urban biodiversity. Plants in the ground need to be watered less than potted plants.

Climbing plants growing in a facade garden allow the covered part of the facade to remain cool in summer. If fruit-bearing plants, such as grapevines or redcurrants, are used, the fruit offers food for yourself and, for example, birds.
