Of course, it can be reduced, but why should it? Budget-wise, everything is fine. Space can be used wonderfully in many different ways.
So, to summarize:
- Door to the kitchen from the hallway.
- Possibly a pantry (in the relatively large kitchen, in my opinion, there is plenty of space even for parties, which are the exception)
- larger utility room
- larger children's bathroom
- wall for 2 children's rooms to be built from the very beginning (could be used as an office)
- "reasonable" staircase to the attic?
