The paper discusses the concept of mega-object, which is a review of the relationship between the object and the environment from the perspective of enhancing specifi c individual actions of the designer. The central aspect of this conception is an individually executed model of an urban landscape fragment, which is one of the key subsystems of the environment. The fi rst thing that this model does is to achieve the plastic integrity of the form of an environment fragment. As a result, from the perspective of this concept, some single object cannot be fully eff ective without being an integral part of this whole. All modeling procedures developed in the composite method introduced by the author are subordinated to the idea of assembling or cutt ing the body of mega-object. The composite method here serves as an organic link to art, fi rst of all, to plastic art. The article emphasizes the importance of Frank Lloyd Wright's activities as the founder of an organic architecture, gives a classifi cation of mega-objects and describes how they are dependent on the so-called "Size scale" of the composite method design.
