A site plan of the property would not be bad. I have to be honest: I would not be happy in a house without south or at least west sun. Our driveway and street are also on the south side, yet the kitchen, dining, and living areas face south. The entrance is on the east side. Are you building without a basement? Is this utility room sufficient for technology, laundry, and storage space? I don’t know how often you have guests, but I would skip the guest room and instead plan for a pantry and possibly a wardrobe. If guests are not the norm, then a children's room can also be freed up. If there is no guest room, then also no shower on the ground floor. Nobody uses it anyway.
