Dezeen spoke to Bernard Tschumi about deconstructivism in an exclusive interview

We continued our series on deconstructivism with an interview with architect Bernard Tschumi who argued that the architecture style was built on a desire for exploration that contemporary architects do not share.

"When you asked me what was deconstructivism's impact on contemporary architecture – that's where I want to retreat at the back of the room," he told Dezeen.

"So many corporate firms have literally learned too much, but purely about the image-making part of the deconstructive period."

The cross-shaped building is concealed in a forest and stores 1,400 tons of carbon dioxide in its mostly-wooden structure.
