Turfstone
The starting point for the design is the lawn ironstone widespread in the groundwater soils of the landscape area, a layer cemented hard mainly by precipitated iron in the sandy soil that dominates here. Once a raw material for smelting iron by hand, it was also used as a building material in a natural area poor in stones and can be found in the masonry of numerous historic buildings in the region.
The main idea of the design concept was to make the "iron" in the soils of Langenhagen visible in the design of the park entrances by means of landscape architecture, to highlight it from the subsoil, as it were. The image of a tectonic fault, where the ferruginous soil horizon emerges, is the subject of the design.

Design concept
In order to make the lawn ironstone lying beneath the earth's surface "visible", the design provides for weatherproof structural steel. Like a tectonic fault, the ferruginous soil horizons visualized by the rusty surface of the steel "come to light" on both sides of the park entrance. While the corten steel corners are similarly sloped, the earthen bodies are planted with maintenance-extensive plantings of perennials and grasses. The perennial plants, which are rather rare in the urban area, highlight the striking design of the entrance. The ground beneath the plants is covered with a mineral mulch layer of gravel-crushed turf. Thus the rusty steel and the mulch contrast very appealingly with the green of the plants.
