WOW!! You are SOOOOO lucky!! To even have a "kitchen" in your area!!! And I thought I was lucky to just recently have gotten the Loft area of our townhome for my studio!!!!
As for a design "wall" why not try the idea I am going to do...
Take a large (old fashioned) window shade and replace vinyl with flannel or cover vinyl with flannel....That way you can put up high, like above one of those side windows, and just pull it down when you need to use it, and then "snap" it back up when not in use! I saw idea on internet but they wanted Boo-coo bucks for it!! Going to try making my own!
