[8][9] In the 1920s, August Siekmann established a factory to produce kitchen furniture on the site of the Cologne-Minden Railway Company.

During the Second World War, large sections of the factory site were destroyed, yet the company resumed kitchen production in 1946.

[12] SieMatic manufactures kitchen furnishings including cabinetry, countertops, interior organization systems and accessories.

[19][20] For several years, the wood chips and dust accumulated during production in the SieMatic factory in Löhne have been collected and used as an energy source to heat the company headquarters.

SieMatic dealers are located in cities across the globe including Sydney, Chicago, Dubai, Dublin, Oslo, and Seoul.

[23] SieMatic is also involved in the multi-unit market,[24] and its kitchens feature in luxury developments such as the Ritz-Carlton Residences in Chicago.
