sheets of paper and metal into three-dimensional shapes – were shown in a Bauhaus exhibition. In April 1927, Hannes Meyer was appointed head of the building department and Sharon was to be greatly influenced by his teacher's pragmatical and functional approach to architecture. In 1928 he and two other Bauhäusler, Gunta Stölzl, head of the Bauhaus weaving workshop and the student Peer Bücking visited the Vkhutemas Academy in Moscow, an avant garde art school with similar aims as the Bauhaus. In 1929, some time after their return, Sharon and Stölzl were married and their daughter Yael was born. In the same year, he received his Bauhaus diploma and was immediately put in charge of Hannes Meyer's architectural office in Berlin, to supervise the construction of the Bundesschule des Allgemeinen Deutschen Gewerkschaftsbundes (ADGB Trade Union School) in Bernau bei Berlin. Next to the Bauhaus school buildings in Dessau, it was the second largest project ever undertaken by the Bauhaus. The building underwent an extensive restoration which was completed in 2007. It is a protected building and in 2012 it was proposed for World Heritage Site listing.

In 1936 the two divorced. Sharon's first commission in Tel Aviv was the construction of four pavilions for the Histadrut (General Federation of Labour) exhibit at the Levant Fair in 1932. These pavilions, for which he had won first prize in an architectural competition, were composed of modular wooden elements, progressively growing in height and length, covered by jute. There followed a series of buildings in the so-called international style which would help define the city's architecture as the "White City." In addition he built residential cooperative housing estates, private houses, the central administrative seat of the Histadrut in Tel Aviv, and in 1936 his first hospital for 60 beds, near Tel Aviv. Sharon's housing estates, known as Meonot Ovdim in Hebrew, were built around large garden patios in the center, a continuous group layout, a public space for the residents, while communal services, such as a kindergarten, laundry, shops, and synagogue were placed on the ground-floor. A distinctive feature of Tel Aviv's townscape are the pilotis on which most of the apartment buildings in the residential quarters are raised. This feature was achieved on the
