Collective form represents groups of buildings and quasi-buildings- the segment of our cities. Collective form is, however, not a collection of unrelated, separate buildings, but of buildings that have reasons to be together.
Most collective forms that are present today simply evolved, they have not been designed. This give some reason why today so many professionals often fail to make meaningful collective forms.
Compositional form: preconceived elements and predetermined separately. It is the natural extension of the architectural approach, because the act of making a composition itself has a tendency to complete a formal statement.
The megastructure: large frame in which all the functions of a city or part of a city are housed. A manmade
feature of the landscape – many and diverse functions amy beneficially be concentrated in one place.
Group form: a system of generative elements in space. Consistent use of basic materials and construction
methods as well as spontaneous but minor variations in physical expression.
It is worth noting that generally group-form evolves from the people of a society, rather than from their powerful leadership.
The element of group form is often the essence of collectivity.
Both Kahn’s definition on ‘Form’ and Voelker’s on ‘An open form’ express their desire to produce a form that would be a catalytic agent which may become many forms rather than just a form for its own sake. In any event we predict that in a coming decade the investigation of regional expression in collective scale will become one of the most important and fascinating issues of architecture and planning
