I found this interesting place which is in Mexico. Generally, concrete used as an industrial material, so I thought that it is good for simple and inorganic design. However, this article shows how concrete can coexist within natural environment like a jungle, and it inspired me a lot. The reason why concrete can fit into the place naturally is it is liquid and it can change forms. It also have a long time history since Ancient Egypt, and even now, concrete has a possibility to invest new ways of use for construction. As you see the picture, the building located inside a jungle, but there is no walls and windows, which is good to feel nature and one strategy they used is two trees passes completely through the roof.
