3D VORONOI Semi Orthogonal Script

Hello!

I am creating a pavilion using 3D Voronoi in grasshopper, the idea is that people should be able to walk inside the voronoi cells, I was wondering if I can adjust the cells so some of them have an orthogonal or semi orthogonal floors. 

I am attaching an image of a project that did something similar to what I need, and also the script i have so far.

Thanks.
