The grand home on Heynstraße 8 was commissioned in 1893 by Pankow resident and cane furniture manufacturer Fritz Heyn. To this day, the stairwell still displays the original paintwork. Heyn and his family lived on the first floor – the “Belle Etage” – which today houses the Pankow Association of Museums' (Museumsverbund Pankow) permanent exhibition of upper-middle class living in 1900. Thanks to Heyn's two daughters, who lived in the building until their death in 1972 and made no changes to their surroundings, the original fittings and some of the furniture remain untouched. The rich decoration and paintwork on the walls and ceiling of the drawing room and the study look exactly the same as they did more than a hundred years ago. The apartment also features a typical "Berliner Zimmer" ("Berlin room"), a bathroom with tiled walls, a kitchen and a tiny maid's chamber.
Special exhibitions depict what life was like for Heyn's family and for other residents living in this building in northeast Berlin around 1900. The Museum's ensemble is a protected historical monument and includes the apartment building, a front garden and a garden courtyard and pavilion that can be explored during the museum's opening hours.
