Congratulations on the house
It is not optimal on the ground floor, but certainly not terribly bad. Of course, in the dark season, there may be a lack of light; in summer, you are happy about that. Summers are supposed to get hotter anyway.
You decided to build that way, and the reasons are still valid. Everyone who builds a house has probably had a "if ..., then ..." moment at least once. Recall the reasons for the decision in your mind and mentally arrange your house. Look forward to moving in.
