Korttelialue

Korttelialue refers to a city block or a group of blocks within an urban area. It is a fundamental unit of urban planning and land use, typically defined by streets and containing a collection of buildings and open spaces. In many cities, a korttelialue is characterized by its zoning regulations, which dictate the types of activities permitted, such as residential, commercial, or industrial uses. The size and shape of korttelialueet can vary significantly depending on the city's historical development and planning approach.

Historically, the concept of the city block has evolved from medieval street patterns to the more standardized grid systems common in many modern cities. The arrangement of buildings within a korttelialue, along with the presence of courtyards, alleys, and public spaces, contributes to the overall character and functionality of the urban environment. Planners often consider the density, mix of uses, and accessibility of a korttelialue when designing or redeveloping urban areas. The term is particularly prevalent in Finnish urban planning contexts, where it serves as a key descriptor for spatial organization.
