Due to the growth of population and industrialisation since the middle of the 19th century, new urban quarters arose all around the historic Berlin Mitte; these crossed over into the old suburbs, such as the Spandauer and Rosenthaler suburbs, and situate themselves up until today like a band of stone around the city centre. The foundation was formed in 1862 from, construction engineer and city planner, James Hobrecht’s drawn up so called “Hobrechtplan”. The for Berlin typical perimeter block structure of a manorial front-building with stucco façade and dense inner-courtyard architecture arose within the S-Bahn Ring. Examples of more residential accommodations from the founding-period are found all around the Kurfürstendamm in Charlottenburg and Wilmersdorf. In the southeast, Friedrichshain, Kreuzberg, and Neukölln are formed, and in the northeast: Prenzlauer Berg, Moabit, and Wedding, the rather proletarian forged traditional tenement town.
