Does one who inherits a three-story house bear the cost of finishing the unfinished floor, and what is the share of each heir in this cost?

If the mature son and daughter agree on the division of the house and are content with it, then the division is considered binding, and neither of them has the right to revoke it against the other. However, if there is no agreement or if they are not mature, then the division is not binding and must be adjusted by dividing the house or its value between them, with the male receiving the equivalent of the share of two females. If the son renovated the house, he has the right to reclaim the renovation costs from the inheritance, unless he donated them.
