Centralized/Arrayed Windows and Door

Hello, I am making an code for an georgian typology and I would like to know how I can create an windown and door centralized on my buildings. I have the base of building created from the offset curves from the property lines.

However, I would like to create an odd numbers of window that is symmetrical, both in 1st and 2nd floor. However for 1st floor, I would like to include one huge door instead of the window. I attached the similar image that I am looking for.

Its my first time in grasshopper and I am totally lost with where I should be starting from. I would really appreciate the helps! Thank you!
