Division of a semi-detached house along the roof ridge

A fairly massive semi-detached house was also built here. It faces the street with its gable, although according to the development plan it did not have to be that way. The more practical division of the former single-family house plot probably played a major role in this. Unfortunately, I do not know the floor plans. Upstairs, due to the lack of skylights, there is likely a very dark attic space. That can certainly be solved better.
