When travelling by train from Stockholm to Gothenburg you pass this building just west of Gnesta. It’s called Tvålfabriken (=the soap factory) and was designed in the 50s by Ralph Erskine. (I like how the speed of the train skewed the photo…)

Below is an areal photo with Gnesta station by lake Frösjön (bottom right) and the area Vackerby (top left) where the building is located.
