I would do the cabinetry in the yellow from the windows with a butcher block top to mimic the wood tones of the counter stools.

i was thinking old barn beams posts with partial cabinets below in old barn wood, with concrete counter top with a butcher block section?

I would use the same counter, I think. I might consider doing a very dark color on the cabinets - similar to the floor?

I agree with HERE Design and Architecture. You've already got alot going on visually in this space, might not want to throw too much more at it.

By the way, love the cabinet you've got under the counter at the end - very clever.
