Jessie has already shared the smartest approach to the transitional shapes. The idea is to build it up or cast the weird stuff, until you get to a shape/profile you can easily work with plywood.  You will NOT want to try to make curves with 3/4" birch ply, so use this for the straight walls and lay up thin ply layers over a frame for the curves.  The price of plywood is currently at a 2-year high.  Good luck finding good 3/4" birch ply under $60/4X8 sheet.  Some birch ply will edge shatter if nails are placed too near the edges, so be mindful of that.  I recommend pre-fitting and then gluing everything in addition to nailing with ring-shank nails.

Best regards,
