61 TimberTower 30 Stories 100 m equell to 30 stories Fotos: TimberTower Fotos: MGA Vision.. Lots of Thinking.. Reality Conclusion according to my experience, innovative solutions can create new markets for timber applications large wooden structures are possible we do have the technical knowledge to do it the composite approach will help us to compete with steel and concrete in price and performance... the benefits for the environment will be the bonus! 61
