Ossip (Yosef) Klarwein was a Polish-born German-Israeli architect who designed many works in Germany and Israel. Between 1921 and 1933 he was employed with Johann Friedrich Höger, and became chief design architect. Klarwein was an important representative of Northern German Brick Expressionism and of modern architecture in Israel.

The term Brick Expressionism describes a specific variant of Expressionist architecture that uses bricks, tiles or clinker bricks as the main visible building material. Buildings in the style were erected mostly in the 1920s, primarily in Germany and the Netherlands, where the style was created.
