The plates look super! (And don't worry about "us" being upset! You are following your heart, and only you know your daughter ... we certainly don't!) :-) I love that Kaufmann fabric that Rita shared. That's along the lines of what I was envisioning early on for this space. Fun, fresh, young, a bit bohemian - I think that would really rock!

You’d have to narrow the wide opening in order to fit pocket doors, but you also have some hvac and electrical to deal with that I can see which might still make pocket doors problematic. What if you just walled off the dining room and have the only entry to the office be via the hallway? Or narrow the dining room opening, do traditional French doors and a long transom on top? I think you could get away with traditional French doors in the entry foyer also, but again, that’s a lot of French doors and they wouldn’t be terribly effective at blocking sound.

I also love your table... such a meaningful piece. here are a couple more ideas for chairs in a couple different styles... https://www.ballarddesigns.com/ada-dining-chair---set-of-2/furniture/dining-kitchen/dining-chairs/537025?uniqueId=537025 https://www.ballarddesigns.com/elda-dining-chair/furniture/dining-kitchen/dining-chairs/544233?uniqueId=544233?&defattrib=Finish&defattribvalue=NOK I think the table deserves a crystal chandelier of some sort. I would consider going to an antique store and seeing if you can find a vintage crystal chandelier... here are a few more, but non vintage https://www.ballarddesigns.com/lucille-faceted-crystal-chandelier/lighting/indoor-lighting/chandeliers/555170?uniqueId=555170 https://www.lampsplus.com/products/emelia-19-and-three-quarter-inch-wide-antique-brass-and-crystal-pendant-light__58n45.html https://www.lampsplus.com/products/magrite-26-and-one-half-inch-wide-gold-6-light-chandelier__64v77.html https://www.lampsplus.com/products/calylah-21-and-one-half-inch-wide-chrome-and-crystal-chandelier__56n57.html I think the dining area rug should be colorful and also like the idea of a persian style. agree it needs to be bigger and should fit the table and chairs on it when chairs are pulled out. https://www.rugsusa.com/rugsusa/rugs/rugs-usa-tribal-embrace/Red/200MJSH04A-P.html https://www.rugsusa.com/rugsusa/rugs/rugs-usa-printed-tribal-medallion-flatweave/Orange/200MKCL09A-P.html https://www.rugsusa.com/rugsusa/rugs/rugs-usa-printed-floral-flatweave/Rust/200MKCL11A-P.html

With what you have shown us …it does not look like it is feasible…with more info … a floor plan…better pictures of all the adjoining spaces… a better understanding of you needs for the office space… other ideas may develop…I agree with PPF… this will likely require a contractor… if you can find one that is qualified and willing to do more than just build walls
