Conceptual design of a visitor centre 

In this project, we transform a former lignite mining spoil tip into a recreation and leisure space. Our project for a visitor center aims to create an atmosphere of playfulness and friendliness, while at the same time ensuring a high level of architectural quality and sustainability.

As the existing figure of the Indemann (observation tower) dominates the site, our design does not attempt to compete with it. Rather, the proposed solution uses the consistent proportions of the observation tower in plan and elevation to seamlessly integrate the new volume into its surroundings. By referencing the dimensions of the Indemann in a reduced scale, a building with a friendly attitude towards its larger neighbor is created. The orientation of the cantilevered roof in the direction of Indemann's northeast-facing arm gives the impression of an "animal" companion standing by its side. The new visitor center is an elegant, simple and compact square volume with a cantilevered roof that protects the entrance area. The new visitor center forms an inviting square that connects the entrances to the various activities within the area, such as the Indemann, café, visitor center, footgolf pitch and more.

The building has a simple, modular structure based on a 2x2 meter grid. Its walls are made of rammed earth, and the ceiling of a system of wooden beams that follow the floor plan grid. Such wooden structure defines the character and atmosphere of the spaces and allows a clear division of the interior. Therefore, the floor plan of the building is simple and can be used flexibly. The central part of the building serves as an exhibition area, information center and an inviting space for visitors. This cross-shaped central space offers views of the surroundings through large windows. The exhibition area becomes a heart of the building and also houses a separate seating area to be set up as a waiting zone for visitors. Thanks to a curtain system, the space can be redesigned and further subdivided into different layouts according to the daily needs of the users, and can also be adapted to changing requirements in the long term.

The building designed with proposed means is not only sustainable, but also guarantees low operating and maintenance costs in the long term thanks to compact design in combination with a highly thermally insulated building envelope, optimized use of daylight, use of renewable energy and a reduction in electricity consumption through use of photovoltaic panels.

The form of the building, which is made of solid rammed earth, is designed as a counterpart to an open-cast mine. The choice of materials ensures exceptionally good recyclability and low resource consumption. This also takes into account the idea of sustainable construction and circularity. Large wood-aluminum windows provide the rooms with natural daylight, while external sun protection reduces external heat loads during the summer months.
