Residential architecture in Poland
Residential buildings in Poland are fundamentally divided into two main categories: single-family buildings (houses), and multi-family buildings (blocks of flats, apartment buildings). The former are meant to house only a small number of people, either one or a few families, while the latter are built with larger amounts of people living in their own separate areas of the same building in mind.
