Germany must learn to build vertical than horizontal
In Germany, restrictive building regulations limit high-rise construction in most areas. Depending on the federal state and local community, developers may be restricted to a maximum of, for example, four stories in urban areas, and only two stories in smaller towns and villages. This low-rise approach has significant consequences: land is scarce and expensive, and new development areas often become densely packed with closely spaced houses, each with minimal garden space. In cities, green spaces are increasingly being converted to fill urban gaps—a practice known as “Nachverdichtung”—which consumes large areas of greenfield land and disrupts natural ecological balance.
These green spaces could instead be used to plant trees, shrubs, and flowers that support urban biodiversity, providing habitats for birds, insects, and other wildlife. This approach would help foster a more sustainable coexistence between urban development and nature, allowing cities to retain vital green corridors for ecological health.
This „Nachverdichtung“ also interferes with the natural water cycle. By covering large areas with buildings and streets, water is directed into sewer systems instead of seeping naturally into the ground, which disrupts groundwater replenishment and affects overall environmental health.
Germany has only one city with a notable skyline—Frankfurt am Main. The limited adoption of high-rise buildings in Germany isn’t due to technical constraints but rather to enduring political and cultural preferences. A strong emphasis on preserving traditional cityscapes has shaped urban planning, with many cities reluctant to alter their historic character. Additionally, high-rise living carries a stigma rooted in the post-World War II era, when “Plattenbau” prefabricated high-rise complexes were associated with social issues and became symbols of poorly planned, low-quality housing. This legacy has left a lasting reluctance to embrace vertical development.
To address the country’s pressing housing needs, Germany must explore new concepts that welcome diverse types of housing for various income levels, from luxury apartments to middle-class and affordable housing. Examples from cities like Singapore show that high-density living can be both attractive and sustainable. With more high-rise residential buildings, Germany could ease the pressure on its property market, create more space for green areas, and reduce the impact on natural groundwater systems. Embracing vertical development could offer a way to balance growth with sustainability, preserving green spaces while providing housing that meets modern needs.
