LANGE TAFEL

2025
The “LANGE TAFEL” is a twelve-metre-long table for the “FORST” experimental area of the SDG+ Lab Kassel. Workshops, events and leisure and educational activities are to take place on a brownfield site in a residential area in summer 2025.

The table consists of four individual segments made of CNC-milled multiplex parts, which are connected using tensioning straps and can therefore be easily assembled and dismantled.

Mobile table tennis table for the special exhibition “Was zum Quant?!” as an extension of the outdoor installation in front of the Forum Wissen.
The table is secured on site by foundations, but can also be easily rolled to other locations for activities and events. The banners on the sides serve as advertising media and can be adapted to the respective special exhibitions.

NACHGEFRAGT

2024
Mobile information and enquiry station for exhibitions and events at various locations of the Nachgefragt research project, which investigates the provenance of objects in museums.
Posters and information can be attached to the back wall. Completed questionnaires can be dropped into a slot on the surface. Storage space is inside the box.
The roof and back wall can be removed for transport. This means that the station can be easily moved and set up by one person.

DEINE FRAGE AN DIE WISSENSCHAFT

2024
Deine Frage an die Wissenschaft (Your question to science) is a participatory exchange project that mediates between society and science.
Anyone with a question can write it down at the station and drop it in the letterbox. Selected questions will be answered on social media by the museum team in collaboration with scientists from the University of Göttingen.

PUBLIC SPACE INSTALLATION

2023/24
In order to bridge the gap between the museum and the public urban space, the installation on the square in front of the Forum Wissen will make the space usable and offer a first glimpse of the contents.
The installation consists of five objects on a red steel frame. The surface made of larch planks offers opportunities to linger, lean and rest. A red tape on the floor, on which various questions relating to the museum's themes are written, links the objects to each other.
The individual elements are modular designed and can be rearranged with each other.

T_1016

2021

T_1016 is a table for universal use. The narrow tapered legs made of ash wood are attached to the table top by means of powder-coated metal connectors.
The Egger Perfect Sense Topmatt coating provides a haptically soft yet robust surface. A filigree bracing system with wire ropes provides the necessary stability.
All parts are easy to separate and replace.

RAATHAUS

2020

For KW 36 (Kassel Museum Week) we designed and built the Raathaus on Friedrichsplatz in Kassel. The pink pop-up installation is an interactive platform for people to discuss and debate what makes a city beautiful and worth living in. Over five days, people exchanged, discussed and wrote over 1000 comments and contributions on the walls of the house, ranging from social, political, cultural and economic topics.

COLD DRIP 2000

2019
Cold Drip 2000 is used for the production of Cold Brew Coffee, at the same time it creates interest in the rather unknown coffee specialty. Due to the clear design, the extraction process becomes transparent and the dripper serves not only as a device but also as a communication object in the café, which attracts attention. With a volume of 2000 ml, the needs of small and medium-sized cafés are roughly met.
