For the redesign of the station forecourt in Raunheim (Figures 3, 4, 8), five new textile sail structures in the grouping 2-2-1 were designed by the open space planning office viaverde as a waiting room canopy for public transport passengers. The sail surfaces made of coated fiberglass fabric were attached to steel supports clamped into quiver foundations, as in the city square. The tensionable membrane corner detail already developed by AR-Ingenieure for the town square was supplemented by a controlled roof drainage system that drains the rainwater through the steel supports into the ground, where it is used for direct irrigation of the adjacent tree planting.

For the design of the town square (2017, images 1, 2, 5-7), four textile sail constructions were designed by the open space planning office viaverde. The sail surfaces made of coated glass fiber fabric were attached to steel supports clamped into quiver foundations. This means that there is no need for bracing, which would have been perceived as disruptive in the area of the square. To this end, AR engineers developed a tensionable membrane corner detail that allows the sails to be re-tensioned at a later date. The overall concept convinced the city and was also used in the redesign of the public space around the station.
