Giant Sequoia Skyscraper Concept

For all their grand height, the roots of the giant sequoia don't go down very far — and thus they fall quickly when the trunk starts to rot. The Giant Sequoia Skyscraper Concept aims to merge architecture with nature, filling in the empty trunks with spaces for education, observation decks, labs, and exhibitions. In addition to providing usable human space inside, the design's central core and the lattice-like exterior attached to the bark would help keep the tree upright long after its roots would have failed.
