Soon after arriving in Tallinn, Ackermann settled down to live with Anna Martens, the widow of the guild master Elert Thiele. Ackermann gained the opportunity to freely use the recently deceased woodcarver and master cabinetmaker Elert Thiele’s well-furnished workshop. The house was located in the Olevimägi district (at 4 Olevimägi Street). Thiele gained possession of the house after marrying Maria, the daughter of the woodcarver Lüdert Heissmann, as her dowry. Heissmann had purchased the house from the heirs of Hinrich Lanting in 1652. Heissmann failed to pay part of the purchasing price. This debt was the start of a quarrel that was to last for years.

After Thiele’s death, two children from Thiele’s first marriage lived in the house together with his second wife Anna Martens and her new-born baby, who soon died. Even before a year had passed since Thiele’s death, his widow married Christian Ackermann in April of 1675 when she was already four months pregnant. Together with Thiele’s house and workshop, Ackermann also inherited Thiele’s debts and similarly Heissmann’s debts. For this reason, Ackermann did not continue to live in that house. Instead, he was forced to sell the house in 1679 and to move away from Tallinn to Toompea.

The harbourmaster and French teacher Peter Claudius de Champs purchased the house. After his death and when the difficult war years had passed (the Great Northern War), cabinetmakers and master woodworkers once again inhabited the house and the workshop there.
