Need Help for the architectural surface

Hello everyone，

I am new and i study Grasshopper for a short period of time .Recently I am trying to build some examples of architectural surface by myself, but I failed to think out this architectural surface in the image.I am not sure that  the change rule in the architectural surface I thought is right.It orders that you should keep the brick size remains the same.

I hope you can help me or can give me advice.Thanks a lot!
