Some spaces in architecture have been used in different applications. Hence let us think of some of these spaces which are flexible for the multi-purpose utiliZation of spaces. With the advances in technology the various elements which form the interior spaces such as the walls, floors. and roofs need not be designed in a rigid way. Such flexible options would give more options for flexibility to space and can be called as a multi-application’ space. Prehistoric man started constructing his dwelling using his own ideas. Where nature provided caves and trees were the two main paradigms which acted as shelter, stone, and wooden shelters then came into existence. The next stage progressed with the use of animal bones and skins of animals as he used plains for hunting and agriculture being an occupation. This architectural progression of using animal bones and skins gives an option to flexible opening and closing from the past. Hence from centuries back invention of lightweight structures been utilized by man. The main objective of flexible spaces in architecture is providing spaces that change structure pertaining to the required performance and application. Any space or structure that is designed for flexibility should be identified by their interior elements like a floor, ceiling, and walls where there is a scope of shrinking and expanding.
