ACO Sponge City concepts based on the Stockholm system
The sponge city principle of the Stockholm system describes an innovative construction method that creates an optimal habitat for large-crowned urban trees, while providing retention space for rainwater. The Stockholm system provides a large volume of root space for the tree to use without damaging the infrastructure above. Stockholm, where this construction method was developed over 20 years ago, has played a pioneering role.

“As Confucius said: ‘Take care of the roots - then the branches and leaves can take care of themselves‘!”
