attempting to not make changes as they could be costly at this point (even prior to construction), if you are satisfied with the plan, then there should not be anything more to be concerned with.
About the only real things that stand out at me is:
the amount of space in the kitchen area. Do you have a large island or something in this space? If not, there appears to be a huge waste of sqftage.
The 2nd thing is the sunroom off the kitchen. Is there a reason you have so many doors? Why not consider french casement windows in there and only place doors where you actually need them? That many swinging doors can become an issue with venting. Any breeze will cause them to move around, hitting each other. You can most likely reduce cost some as well by going with windows. just a thought.

Izerarc - thanks for response. My builder builds a great house, but he is lousy with the software! The kitchen as shown on the plan was just a rough design, he's sending me to a KD - but there will be an island (sort of pie shaped) with a prep sink and raised curved bar that will seat 4.

I had to chuckle about all the doors shown on the porch. His software didn't have provision for screen system but that's what it is, no doors, just vinyl screened panels with Trex flooring. We're into very low maintenance.

I'm relieved that you didn't notice anything glaring. There are so many decisions to make, it makes me nervous.

Thanks for taking the time to post.
