Meyer became director when Gropius resigned in February 1928, and brought the Bauhaus its two most significant building commissions, both of which still exist: five apartment buildings in the city of Dessau, and the Bundesschule des Allgemeinen Deutschen Gewerkschaftsbundes (ADGB Trade Union School) in Bernau bei Berlin. Meyer favoured measurements and calculations in his presentations to clients, along with the use of off-the-shelf architectural components to reduce costs. This approach proved attractive to potential clients. The school turned its first profit under his leadership in 1929.
