Modelling in Rhino

Hi everyone, I am trying to do a model of this building in Rhino generated by Midjourney and was wondering if anyone can offer any indications to as what the best modelling practice will be? I have tried doing it in several ways such as CageEdit or drawing out the main curves and sweeping them however the outcome does not seem to match the geometry as on the image. Really appreciate any advice!

Have you tried the SubD tool?
I’m not sure it’s the best way but I would try to do it with this.
Firstly, I would try to create the main mass and then elaborate. A tool that can work organic surface and sharp lines together.
