Zimmerman Art Nouveau Building
The apartment house for A. F. Zimmerman at No. 61 Kamennoostrovskii Prospekt (1906–1907) is a historical landmark building in St. Petersburg designed by the leading proponent of the style moderne, Swedish-Russian architect Fyodor Lidval.
Lidval was one of the most prolific and influential St. Petersburg architects at the turn of the twentieth century. Rightfully celebrated for his style moderne contributions to the architecture the city, he was also a prominent figure in the revival of the classicism. His signature style included extensive use of modern structural and decorative elements, elaborate structural molding, application of different colors and textures; he was also fond of adding a corner tower projecting over the street level (Meltser Building on Bolshoi Koniushennyi, Singer House on Nevsky).
The Zimmerman building is often cited in architecture textbooks for its original and unique design of windows – there are twenty-five different types of windows!
