The parametric tree is aimed to be growing from individual courtyards of the traditional Tunisian homes, and up above, over the existing roofscape, support an additional floor/roof combination to accomodate different programs and functions.

The definition seeks to adjust the tree height and branching span in relation to the courtyard size. Other parameters are number of branches and branch width. All of these - except no of branches, can be adjusted in the current definition, yet each parameter requires a manual change. Ideally, there should be a logic, with which all of these can be changed at the same time, similar to how a real tree grows.

There are a couple problems with the current definition:

1. In order to obtain different branches at the same level, one branch is rotated multiple times. This gets excessive especially in third layer of branches, where 64 branches are required.

2. Section planes placed at branch connections cannot be adjusted to be perpendicular to the direction of growth.

3. When lofted, the branch volumes intersect. However, no method has been found to trim the volumes and cap them again. ‘Boolean trim’ tool simply draws the intersecting lines. Is redrawing these surfaces necessary?

4. How to unroll these branches in a proper way also remains as a question.

5. The possibility to join the top surfaces supported by multiple trees has not been explored yet.
