Buongiorno, I have made several options for, both first and second floor which can be combined. As the construction is not very clear, I created more or less opened spaces. Real possibilities should be checked on site, the position of roof (because of the atrium), pipework... I have also created two tipes of staircases, one smaller and the other bigger. Both can be prolonged if necessary, because of the real hight. Also, new windows could be opened on the first floor, if needed. All kitchens could be closed or opened. I think that the final appearance should be mix of traditional domestic style and some contemporary details. Best regards, grazie.
