There were other variations which resulted from constraints given by the shape of the land plot. If the frontage was wide, then the courtyard was placed in the middle with its long axis (if rectangular) perpendicular to the alleyway. In such a case, the plan was often split into two mirrored arcades with several rooms on either side.
Another variation was a mirrored split of the plan into two similar houses (Twins) but with one entrance which, in turn, split into two. In such a case, the arcade in each house took an L-shaped arrangement. The upper storey was repeated with an arcade or a tarma. A party wall was used to divide the twin houses.
