mixed use tower floor plan galapagos

hi,

i am trying to create a mixed-use high-rise building in grasshopper.

My main goal is to create a tower which adapts to its users.

I was thinking to create different "boxes" per function (office, apartment, hotel...)

Each type of box has different parameters (height width length....)

The next step is creating a tower with these boxes where the boxes are placed at their best location. How can i do this? i know i can use galapagos to get the optimal position, but first i need to know how to place these boxes.

I was looking to do something like Nate Holland in this video:

My question is, how can i do this, how can i build this in the best way?

Are there any example scripts?

Hope that someone can get me on the way!

Thanks

Mari
