Hi all, i hope this finds you well.
i am trying to design a structure that will flow over the roof of my building, the form is very detailed and ultimately is a green wall system. below is a sketch of the idea. the brown tentacles are a 3D sculptural formed green wall system.
the idea is that what is constructed is a timber "tube" arranged on the rooves of my structure and it becomes a custom garden bed that can easily be adapted. cut a whole in the timber, put in the soil and plant a flower.
also as a cooling strategy for the building
what i need is basically to be able to take a sweep, and change point height so that i can make them flow.
that would be enough but would also love to be able change face sizes.

i'm no pro but i'm also not an amateur, i just need some pushes into what i need to look at applying to a model, i've been trying to wrap my head around reference lines and and such but i'm not finding what i want. what kinds of tools should i try to achieve this?
if i find a solution i will be sure to share
