Southwest of the Südfriedhof cemetery, in the "Unter Schwarzenberg" district, now known as Wiesbaden-Südost, the Kalle & Co. AG factory estate was built from 1937 as a small housing estate for regular workers in the immediate vicinity of the so-called Schwarzenberg estate.

After the "Gemeinnützige Siedlungsgesellschaft Kalle mbH" was founded in October 1936, an initial 45 houses were built by 1940 and a further 30 after the Second World War. The estate, located on Hagenstrasse, Giselherstrasse, Guntherstrasse and Utestrasse, was completed in 1955. The early estate houses were modest single-storey buildings with pitched roofs, each with three rooms and a kitchen/living room as well as a cellar, laundry room, stable and hayloft. There was also approx. 800 m² of land.

According to a "leaflet for advising settlement applicants" in the 1930s, only those whose "hereditary health" had been certified by a doctor in the sense of National Socialist "racial hygiene" were eligible as settlers. They did not have to have any capital, but they had to be willing to perform a prescribed number of hours of community service. The Kalle company provided the building site and favorable loans. Monthly payments gave the settlers the opportunity to become owners of the house and land over the years.

The "Siedlergemeinschaft Kalle gegr. 1938 e.V.", which still exists today, celebrated its 75th anniversary in 2013. Documents on the history of the settlement can be found in the Kalle-Albert works archive deposited in the Wiesbaden city archives.
