Re-Silo

Progress in agricultural practices and technology improved production capacities across the globe. The so-called green revolution which started in the 1950s changed agricultural production quantities through the development of high-yielding varieties of cereal grains. As these grains reached their limit new strains which do not exist in nature were created also known as genetically modified organisms (GMOs) which further amplified the production. While the production capacity increased exponentially conventional storage technologies reached their physical limits. The once commonly used steel grain bins were not designed for such capacities. Today, they are replaced by other storage infrastructure resulting in their abandonment. On one hand, this creates redundant structures but on the other hand, it also creates a huge opportunity to extend their intended lifespan by repurposing them into livable space. 

The overarching concept of our proposal is to utilize something that is commonly considered as outdated and unusable. Our proposal aims to re-think the lifecycle of conventional grain bins in the U.S. and to prolong the service life of such obsolete agricultural equipment. Therefore, we propose to repurpose eight old grain bins into habitable spaces culminating into a center for knowledge and learning for the agricultural community. 

The site is limited to accommodate a large number of grain bins. Thus, the neighboring area is characterized by one storey buildings. This surrounding context led us to the decision to reduce the number of used grain bins from originally 12 to 8. Being not invasive with the landscape, but complimenting it with the eye-catching steel grain bins is achieved by reducing the occupied volume which ultimately creates a lighter silhouette. From a bird's view the project site depicts a cellular structure. The core area is dominated by the learning center which provides space for workshops and lectures. Thus, it functions as the main entrance with a reception. This larger grain bin is achieved by reusing envelope sheets retrieved from the cut outs of the other grain bins. The interior is designed open and free, which creates a void that leaves room for thoughts and the possibility to experiment with the space. The combination of a green roof and skylight above creates a dynamic lighting along with natural daylight access. The five surrounding grain bins bracket the core. Separated in two floors each yields the capacity to accommodate one person for the time participating in the study program. All units are equipped with a private bathroom, a toilet, shower and sink. The openly designed living area is furnished with a standard single bed, a kitchenette and a small study area. Upper and ground floor follow a similar layout to achieve easy service of water, electricity and heat. Due to the fact that we aim to repurpose equipment rendered obsolete, the focus shifted also towards other parts of the learning facility besides the grain bins. For instance, instead of commonly used furniture we use upcycled furniture like chairs and tables. The cavity in between the buildings gives room for connections which are achieved by light weight steel construction bridges on the first floor. The building foundation is made out of concrete while recycled wood creates an appealing ambience. 

To minimize architectural barriers no stairs or steps are used. The spiral shaped ramp with a maximum inclination of 5° circles around the main building to gain access to the first floor. Railing ensures safe passage. Another objective of our design is to achieve a comfortable environment for the users. This presupposes a comfortable climate inside the lodging units and the learning center. In order to achieve this, passive house standard insulation in combination with a geothermal heat pump system which works with under flooring heating is proposed. Further, the use of triple glazed windows is required. A sufficient air exchange is achieved through regular natural ventilation by operable windows.  

In brief, our design acknowledges traditional agricultural storage systems by modifying  them into more up-to-date purposes. Reutilizing them into livable space creates an experimental learning center that enriches the agricultural community and is accessible to all users. Our proposal invites users to reflect on conventional practices and welcomes inclusive progress. 

Just as the cereal grains were modified to satisfy society's progress and to serve modern requirements and needs, we modified the outdated grain bins and re-utilized them to become human structures.
