Architectural modeling problems

hi everyone, I’m just started using grasshopper for architectural modeling, and I’m truely confused!
I’m not sure how to create forms like below in grasshopper!
can anyone help me to figure it out?!
thanks by the way…:gift_heart:

Hey. can you draw two splines in free hand and then loft them? the image you put looks random. so maybe you need to better understand what you are aiming for
