HELP! How to expand rectangles equally in two directions

[jazznep]

Hey guys

I want to be able to expand the x component of the rectangles in the model in both opposite directions. I also want to fix the y component to the corner point of the polygon. But then I want to expand the y component in one direction, outward from the corner of the polygon, as much as I expanded the x component.

Thank you in advance for your interest and advice!

I am at a beginner level and would be very happy if you could help me. I think the solution will be to adjust the origin points of the rectangles. But I’m not sure and I couldn’t figure out how to do it.

would you mind sketching over your image even a very rough view of the final result you’re looking for?

Of course, with gratitude!

Here is my final request. (There was a small mistake you see sorry)

this might be one way (rectangle starting height can be calculated with math instead of pull, but I’m lazy )
