Organize the rectangle next to each other

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 the 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 marked the problem in the script.

Maybe someone can have a look and give me feedback...THX!

I am very grateful for the help.

Thx, Alexander
