Ground Plan Organization

Hello Guys,

I would like to create an optimized ground plan.
On the picture down you can see 3 steps from my work. My problem is to step 3.
1 - ground plan diagram with plugin Space Syntax
2 - Middle Point with rectangle + gene pool

Problem 3 (i did it in rhino) -I would like to arrange the rectangles next to each other and later I would like to optimize these on an area in size and shape. I have no idea yet. I uploaded the grasshopper script, i need still some help. Maybe someone can have a look.

I am very grateful for the help.

Thx, Alexander
