Are you looking for a room divider? [houzz=] [houzz=] [houzz=]

I would remove the cover you have on table right now. Just wondering if your furniture is Japanese , just curious :) also details of windows seems to have some Far Asian influence. I would brighten the table up with a bowl of flowers to match the scene, chair covers too with tie backs, table mats, and rug under table. Try to colour coordination table accessories, chair cover, rug and curtains. Center the table in the middle of room and add sideboard near window or corner display cabinet.

I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

You will need space to walk and for your feet if you turn the chairs around - if you put a divider in you will block the view from the dining table out to the balcony - and thus make the kitchen and dining room both have no view ! So if you keep it open, the natural light can get through !
