offset domain curve intersection

Hi there, I am trying to make a brick like system were i can automate the distance between each brick and its rotation according to a profile curve, however I am having difficulties aligning the distance between each brick on grasshopper.

Ideally I would want the offset curve to intersect with the corner of the edge of the previous brick. here is a screenshot and files of what I am trying to do.

so the offset curve is based on the projection from the domain curve that creates a rectangle, but I want to move the domain point in which to let the offset curve intersect exactly with the corner of the previous rectangle.

I hope someone can be of any help.

Thanks
