In the liturgical context, for example, he designs baptismal fonts, paraments, tabernacles, lecterns, altar tables and furnishing details from candlesticks to door handles. His designs are characterised by clear form and subtle details; function and design are consistently linked, far from any ornamentation.

In Felger’s applied works, the connection to free art always remains noticeable: a stone stele with a sculptural appearance is only recognisable as a fountain through the tap discreetly set into one side, the wavy lines carved into the limestone of a baptismal font have something graphic about them, the colour gradients of the paraments are reminiscent of paintings.

In 1974, Andreas Felger designed a ten-metre-wide mural for the indoor swimming pool in Mössingen made of 280 ceramic tiles individually fired for this project. The landscape of the Alps, abstracted into a brightly coloured composition, blends into the architecture like a window view.

Among other things, numerous design objects by Felger were documented for the first time in the work groups of the KUNST.STATIONEN.
