you have attached a Rhino file containing two cubes and a rectangle curve… no gh file .___.
something like this could be a starting point, I would use Pipe instead of Multipipe:
weird_pipes.gh (13.4 KB)
the above resembles the look of the pipes running along the frames, but if you want to mimic also the composition method used in the picture, I think the base module is more this (dirty sketch):
weird_pipes_base_module.gh (21.3 KB)
