Porrastupa

A porrastupa is a type of residential building found primarily in Finland, characterized by its common entrance shared by several apartments. The term "porrastupa" literally translates to "staircase room" or "stairwell dwelling" in Finnish, referring to the central staircase that serves as the access point to individual living units. These buildings are typically multi-story, with apartments located on each floor accessible via the shared stairwell.

Porrastupa buildings are a common form of apartment housing and are found in both urban and rural areas of Finland. They often feature a functional and straightforward architectural design, prioritizing efficient use of space and shared access. The design emphasizes communal living by providing a central point of entry for residents, fostering a sense of neighborhood within the building.

The apartments within a porrastupa can vary in size and layout, catering to different household needs. They often include standard amenities such as kitchens, bathrooms, and living areas. The construction of porrastupa buildings became widespread during periods of significant population growth and urbanization in Finland, providing a practical solution for housing a growing number of people. Maintenance and upkeep of the common areas, particularly the stairwell and entrance, are typically managed through a housing cooperative or property management company.
