katusekorrus

A katusekorrus, a term originating from Estonian, refers to a story or living space located within the roof structure of a building. This architectural feature is essentially an attic that has been converted or designed for habitation, making it a distinct living area. Unlike a traditional attic used primarily for storage, a katusekorrus is intentionally finished and furnished to be comfortable and functional for people to live in.

The key characteristic of a katusekorrus is its integration with the roof's slope. This often results in rooms with angled ceilings, which can present unique design challenges and opportunities. Windows are typically integrated into the roof itself, known as dormer windows or skylights, to provide natural light and ventilation. The exterior appearance of a building with a katusekorrus may feature these dormer windows protruding from the roofline.

The concept of a katusekorrus is found in various architectural styles and historical periods, particularly in urban environments where maximizing usable space is important. They can be found in apartment buildings, houses, and commercial structures. The creation of a katusekorrus can involve either the renovation of an existing attic space or the deliberate design of a new top floor that follows the roof's contours. This type of living space can offer distinct advantages, such as unique views and a sense of seclusion, but also potential drawbacks like temperature regulation challenges due to direct exposure to the roof.
