Extrude along a vector (vector in the middle, not on the outside edge)

My project is an urban study of buildings
which the building height controls over the exposure (+ u zoning density building depth).

It works.
However, I want the reference axes (the axes of the building) not on the outside edge of the building, but in the middle of the building.

Im begging for help.

I would be very happy if you could revise my added GH file (the rhino file is attached too)

Below is a graphical representation.

Does the axis need to move or the building?

The Rectangle component's inputs are domains not numbers. When you supply only a number it is converted into the domain 0 to 30. Where as if you supplied -15 to 15 you would get the axis down the middle. Change the expression on the domain component to something like -A/2 and B/2 to get what you want. see attached
