The spaces have two distinctions: Exterior and Interior.
Exterior space has two distinct zones: One where the extent is endless or beyond the limits of perception and, Two where the perception is limited by the physical edges. These ‘limited’ exterior spaces are the ‘neighbourhood spaces’. Very vast exterior spaces are recognised through intermediate markings. The neighbourhood spaces on the other hand are finite, shaped and sized by the bounding elements. The bounding elements are exploited or improvised.
Interior space consists of Core and the Peripheral sections. The core could be static, physical, and spatially centric, or temporally transient and metaphoric. The core is less variable then the peripheries made vibrant by the surroundings. Interior spaces for inhabitation require greater degree of interventions then anything nature can offer or can be improvised upon it, so are deliberately designed. For such interventions different types of spatial definitions are used.
One of the most important formative processes for interior space is the environment. That is why, the space and environment though two distinct entities, condition the human behaviour as a single happening. Since environment is ever evolving and so varies the space continually. As the space changes with time, so does the behaviour of the occupants. In other words’, the behaviour changes with space and time. A space with irrelevant environment is abandoned, improvised, or adopted by inhabitants with change in a lifestyle.
Some aspects of environment change with predictable periodicity (light, seasons, etc.) whereas other factors are unpredictable (wind, rain, etc.) The occupant or the user has different levels or receptivity. The same space could be depressing or inspirational at different times, because the environmental conditions are changed, and because the bio system of the inhabitant gets set to a different mode. The space has a subjective significance to its inhabitants.
The inhabitants develop a dynamic approach to sustain the occupation of a space. Essentially minor changes are accommodated at personal and passive level, i.e. by recasting of the lifestyle, body posturing, metabolic activity, rescheduling, etc. At micro level the changes are absorbed by activities like repositioning of the furniture and facilities, establishing improved amenities, etc. At macro level the changes are assimilated in terms of additions, alterations, renovations, etc. in the built form. At a radical level the changes may force recasting of the group-dynamics (treaties, friendship, divorce, etc.), or migration to new locations.
The environment is conditioned at many different levels:
- Environment conditioning primarily occurs at a personal level, when a human body adapts itself to the environment.
- Clothing provides the cover.
- By rescheduling and relocating tasks, substantial degree of environmental adjustment can be done.
- Barriers are formatted to meet the challenges of the environment.
- Moulding of a space configuration to reform the environment, by inward and outward transgressions.
- By modifying or exploiting surrounding elements (buildings, slopes, hills, trees, caves, valleys, gorges, etc.) the environment can be controlled.
- Specific amenities and facilities to regulate and exploit the environment.
- At another level beliefs, feelings and experiences help overcome the apprehensions and master the environment.
In an Interior space, the environment in spite of being contained and controlled, remains an ever-changing enigma, and so do the responses of our body.
