The article analyses modular artistic forms that emerge in all scale structures of contemporary architecture. Module, as a standard unit of measure has been in use since antiquity. It gained even more significance amid innovative building and computing technologies of the 20th and 21st centuries. Static and fixed perceptions of a module were supplemented with concepts of dynamic and adaptable modular units, such as fractals, parameters and algorithms. Various expressions and trends of modular design appear in contemporary architecture of Lithuania, where modular forms consist of repetitive spatial and planar elements. Spatial modules as blocks or flats and planar modular wall elements are a characteristic expression of the contemporary arch...
