We critted yesterday and presented our latest ideas regarding the structure and design drivers.
After looking into the way bamboo grows we found links to the city which we have incorporated into our design.
The "rhizome" is the root structure for bamboo. It is a shallow root system but extremely dense and enables a stable foundation for the bamboo shoots to grow so tall. Comparing this to the city, we noticed that the structure is similar to the underground of a city with a dense network of pipes, services, carparks and underground railways etc. Above ground, there are similarities to the downtown city with a mixture of buildings rising to different heights. We considered the idea of density where, at the base of the bamboo forest, there is a large concentration of bamboo. However, moving upwards, the density lowers as the shoots are not all the same height. A similar situation happens in the cross section of the city, at ground level there are many buildings, but moving upwards, the skyline gets less and less dense.
We also considered the relationship between bamboo and the city in plan. The bamboo rhizome grows outwards from a central bamboo shoot. This is similar to the way urban sprawl occurs with the city slowly growing outwards from the CBD.
We have interpretted this into our skyrise structure though raising the ground level. Our skyrise will not just represent the bamboo forest above ground but the entry to the structure will be through the "dense rhizome" of the sub-terra. The entrance will be a small tunnel surrounded by densely packed bamboo poles. "Above" ground, some of these poles will rise high above visitors to at least the 8 metre minimum height. On some of these poles we will attach ropes and harnesses to enable visitors to our structure the opportunity to climb the bamboo and experience the canopy of the forest.
An animation of this proposed idea is posted here.
