A hexagonal window (also Melnikov's or honeycomb window)[1] is a hexagon-shaped window, resembling a bee cell or crystal lattice of graphite. The window can be vertically or horizontally oriented, openable or fixed. It can also be regular or elongately-shaped and can have a separator (mullion).
Typically, the cellular window[2] is used for an attic or as a decorative feature, but it can also be a major architectural element to provide the natural lighting inside buildings. The hexagonal window is relatively rare and associated with such architectural styles as constructivism,[3]functionalism[4] and, occasionally, cubism.
History
Attic hexagonal windows were occasionally used in the Northern European manor architecture of the 19th century. The concept became popular thanks to the Russian constructivist architect Konstantin Melnikov,[5][6] whose own famous house had 124 hexagonal windows, which were the main source of light as ceiling lights were not provided in many rooms.[7][8] Cellular windows are also a feature of the Scandinavian functionalism architecture of the 1940s–1960s and are a kind of synthesis of tradition and modernism in the architecture.
