SOLID solutions in design GmbH was established by Manfred Gottschling and Klaus Guntschnig in Munich in January 2004.

Over the years, SOLID developed into an acknowledged expert enterprise for the development of exterior modules.

In 2016, by adding the Siebenwurst Group, Germany's biggest tool and mould producer with international locations in Poland, China, Mexico and the United States, as a partner, the way was strategically paved for further growth of SOLID solutions in design GmbH.
