Rusakov Workers' Club was designed by the famous Soviet architect K. Melnikov and was built in the junction of two streets Stromynka and Babaevskaya in 1927-28.
"The Rusakov Workers' Club in Moscow is a notable example of constructivist architecture. The club is built on a fan-shaped plan, with three cantilevered concrete seating areas rising above the base. Each of these volumes can be used as a separate auditorium, and combined they result in a capacity of over 1,000 people. At the rear of the building are more conventional offices. The only visible materials used in its construction are concrete, brick and glass. The function of the building is to some extent expressed in the exterior, which Melnikov described as a tensed muscle". (Wikipedia)
The best architectural creation of Melnikov is considered his house-studio in Krivoarbatsky Lane (link) - an unusual round building with hexagonal windows. Even though it is hard to impress us with anything in the epoch of modern constructivism and the most unusual creative solutions, but Melnikov's architecture still attracts attention.
