Below is the floorplan for the majority of the first floor.

We're not sure how we want to separate the kitchen/dining room/great. We want it to feel open, but each space to be defines as well. We were thinking of putting 18" headers. We have 10' ceiling so it should still feel open.

I really wanted arches, but the arches won't line up. The kitchen and dining room would be separated by one big arch and the great room and dining room 2 smaller arches. Would that look wierd?

We also struggle with how ot separat the great room/hall and staircase. The staircase leads up to 2 bedrooms which my 6 yo is going to use. And downstairs to the bassement. We were thinking of making that wall opposite solid instead of half. And putting a gallery of photos.

And advice on how to separate spaces?
