A completely new type of tree tub has been developed and installed in the Kop van Zuid district in Rotterdam. Trees of up to 15 metres tall grow here without any difficulty here and the tub provides fully automated care facilities. The tub and the tree are movable. This solution is applicable at sites where there are many pipes and ducts in the ground and at future development sites, multi-functional squares, etc. They represent the modern exponent of the Orangerie.
