Physical space is the volume of air bounded by walls, floor and ceiling of a room. It can be measured and computed in terms cubic feet or cubic meters.
Perceptual space refers to space that is perceived, imagined or seen. This type of space is very common in cities characterized by glass buildings but cannot be quantified.
Conceptual space is the mental map or picture that has been conceived, formulated critically analyzed, stored, retrieved and well implemented. Successful architectural designs have their basis on perceptual model.
Behavioral space is used to mean the actual space within which main activities are carried out or utilized. These may include movements or constructions.
Interwoven space is a characteristic model derived from both physical space and perceptual space. The dual nature of this model incorporates two different model designs with an aim of increasing design tastes in architectural works.
According to Nikilaus Pevsner, Frank Lloyd Wright, Okakura Kakuzi among others, architectural design systems are derived from the basic models. These are physical, perceptual, behavioral and conceptual spaces. Examples of derived models are static, fluid, interwoven, positive, negative, interlocked and personal spaces among others. Development of these models helps one to understand the various external factors that highly determine existence of any structure or facility put up in a given area. For instance, in Gothic Cathedral, the physical design was such that majority of the people’s movement is central (towards the alter) in order to enhance concentration of gravitational pull strength that would balance effectively with the building’s weight. Besides, space systems provide the different design tastes to consumers so as to increase market viability on well completed and furnished structures. A good example is the positive space model in Florence city of Italy. Therefore, understanding model designs offer effective foundational approaches to establishing successful architectures whose operational identity would not be easily challenged.
