For chair scoot and sit space, I'd follow the guidelines for a rug - 4' all around. Then you want to be able to navigate around the table while people are seated, so add another 18" all around. Are you locating the table at the end of the galley? Maybe you could use a banquette on one side or in the corner https://www.houzz.com/photos/3rd-street-bungalow-traditional-kitchen-austin-phvw-vp~214425

As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

Wow, that was awesome Mark, thanks for that and everyone else. I thought about the desk facing the other way actually, to avoid feeling enclosed I do have really great views there so I thought about a small couch and maybe a bookshelf on the back, but having the dining table in front is probably not the best either.... complicated :( Here are a couple more pics, today was a beautiful day so I managed to get more of the views

I read an interesting comment somewhere, where a lady invited a group of her friends over to lovingly point out all the problems they saw (through fresh eyes) with her home on preparation for sale. She said she was surprised at marks and damage that she had lived with for so long she no longer noticed them. We "owner built" a home previously, and when we came to sell 7 years later, we painted the garage and did those jobs that we had put off, and it became sad to finally see her at her best, at the end, when we could have been living in a completely finished home all that time. I read about a lady who decluttered her home, had it professionally cleaned (build clean, or bond clean) and had a professional styler do her home and she realised just how nice it could be and decided not to sell. :) ta
