Spaltenräumen

Spaltenräumen is a term used in architecture and urban planning to describe the creation of narrow, vertical open spaces or gaps within a building or between buildings. These spaces can vary in width and depth and are often designed to introduce natural light, ventilation, or visual interest into otherwise solid structures.

The purpose of spaltenräumen can be multifaceted. They can serve as light wells, drawing daylight deep into interior spaces that would otherwise rely solely on artificial illumination. This is particularly common in densely built urban environments where direct sunlight might be limited. In addition, spaltenräumen can act as conduits for natural ventilation, promoting airflow through a building and helping to regulate temperature and improve air quality.

Visually, these slender voids can break up the monotony of large facades, creating a sense of depth and dynamism. They can also be used to frame views of the sky, neighboring structures, or internal courtyards, adding a layer of complexity to the user's experience of the built environment.

The design and execution of spaltenräumen require careful consideration of structural integrity, material choices, and the potential for privacy issues. They can be left open, covered with glass, or incorporate elements like balconies or planting to further enhance their functionality and aesthetic appeal. The concept is often employed in various building typologies, from residential complexes to office towers and public institutions.
