Plochingen is a town in the district of Esslingen in Baden-Württemberg in southern Germany.
It is located at the confluence of Fils and Neckar, 19 km southeast of Stuttgart and the Neckar is navigable from here on.
Plochingen is one of the main stations on line one (S1) of the Stuttgart S-Bahn. The Fils Valley Railway, part of the connection from Stuttgart to Munich, runs through Plochingen, with the Neckar-Alb Railway to Tübingen starting here. The public transport here is good, so that even on weekends bus and train connections are very frequent.
Close to the railway station is a Hundertwasserhaus, designed by Friedensreich Hundertwasser and built in 1992. As this house should "not disturb the traditional skyline of the town", the house is rather conventional on the outside, which is unlike other Hundertwasserhauses. However, there is a single, significant tower in a style typical of Hundertwasser visible from outside the complex. The interior court evokes a typical Hundertwasser style. The courtyard also features a cafe.
