The biggest feedback for our presentation was to “just make it a triangle”- by adding a third structure, the whole thing will become much more stable. One weakness we knew about going into the presentation was the tendency of the roof to deform- more secondary members spanning each roof portion would help resist this tendency, and will probably be necessary even with the addition of a third tree as the forces will only increase without a corresponding increase in the roof’s ability to resist them laterally.
The other challenge with adding another tree is to fit the structure inside the site boundaries- the current iteration is already pushing them slightly, so a third unit will require more careful attention to size. We have a few modifications in mind already- the bench ring could be smaller, for one. The increased stability granted by a third unit should offset the decreased stability of a smaller base, so that’s easy enough to justify.
Beyond that, we need to start focusing in on the connections. The difficulty as beginners to Rhino and Grasshopper is that we’re not sure how to work with connections in Karamba, or generally how to model such detail in Grasshopper. That’s likely where we’ll have the most need for instruction/help.
