Waterstudio.NL is an architecture firm that specializes in creating projects that are on or near water. One of their newest projects is a towering multi-layered structure called the Sea Tree. In an effort to bring back healthy environments to harbors and rivers surrounding major cities, such as New York, these structures would be built in the rivers, lakes, or harbors that often border large metropolises and house not only sea life but also various birds, insects, and plant life.

Prefabricated offshore, the structure would be built and designed to only support plant and animal life above and below the water. A system of cables allows the tree to sway a bit in the wind while securing it to the sea bed; and the height of the structure can be adjusted to suit the selected location.
The design is highly cost effective and Waterstudio.NL’s idea would be to have big oil companies donate the towers to cities to show their appreciation for the environment. Regardless of who would be buying them, this design could have a really positive impact for the environment while not taking up expensive and limited space in cities.
