In public buildings, the floors usually do not exceed three, and the maximum height can reach 13.5–14 m. without the roof (Town Hall). These buildings appear particularly imposing in relation to the scale of the houses, both in terms of the height and area of their coverage, as well as its plastic decoration.
The residence was the main use of the buildings in the old town of Xanthi. In a few cases, the use of the ground floor as a shop, or as a storage area, or as an area for processing tobacco leaves is observed. The category of public buildings includes administrative buildings, religious buildings, educational buildings as well as residential buildings that currently house public functions. Commercial buildings include shops, workshops, and spaces for recreation and social gatherings.
