Pancha Bhutas is an ancient belief that states life exists because of the presence and balance of the five classical elements. They are associated with the five senses. They act as the gross medium for the experience of sensations.

The plan is a closed formation of concentric spaces with coutyard in the middle. The plan is derived from subtractive combination of several built spaces and green pockets. The arrangemnt of spaces is radial; similarly the structure is also radial. The structural formation is derived from circular arragement of columns and slanted combination of radial beams. The building has an semi open circulation though public and semi public spaces. The pattern of circulation is in two forms- radial and circular merging to complete the free and open flow throughout the building. The spaces are vastly open to give maximum exterior green views.

porch Dwelling through curved path from the entrance, the porch gives a firm sign of welcome. Standing on two pillars, the curved shape sweeps one in to the building. The entrance to the building is vastly open and stands tall to enclose the scenic beauty of the rear garden into its frame.
foyer The curved foyer is framed by the walls of office buildings on two sides painted with light colors of yellow and white inviting to enclose in its semi open enviroment. The curved creek of lights leads one into the bright courtyard in the backdrop.

The traditional Indian courtyard is built on the principles of Vastu Shastra, which state that all spaces emerge from a single point, that is, the centre of the house. All other activities revolve around this centre, which has some divine power and energy associated with it. A courtyard acts as a bridge of common space for everyone and has many impacts - social, security and privacy, micro-climate and articulation of space. The campus courtyard is framed by curvacious arrangement of offices and halls located equidistant for appropriate accessibility. The buildings in the backdrop seem to fade by the charm of vegetations in the courtyard. The plants collectively create a space of diffused light that just adds more to the liveliness. The courtyard is perfect place for the dwelling or sitting to capture a moment of restfulness. Circular loop beholds a collection of views distinctive to one another whether from office, canteen, halls, etc. The curved path of step stones marks path for dwellers to connect at opposite ends at short distance.

The courtyard itself is a large light well spreading coming atop. The 20,000-square-foot building was designed around a courtyard - a traditional gathering place for intellectual encounters, cultural functions and social interactions - which acts as a “light well�, providing light to the adjoining rooms. It helps in stack ventilation and forms a safe inside yet outside environment. The natural light from the courtyard, combined with energyefficient lighting systems, results in 88 per cent energy savings, higher than that of an electrically-lit building of the same size. Some 90 per cent of building spaces have daylight access and views to the outside.

Vertical Landscaping is an essential feature of the building. Some have been used as facade element while some as partition. The plants are layed on pouch of dark plastic containers stacked in series and rows. The plants come as filler element. The set is hung with ceiling or stuck on the wall. Vertical landscaping is an influential element to enhance the vibrance of green buildings. Apart from aesthetics, these act as additional mass to the wall and reduce the heat load in the building.

The Jali walls are important feature in Indian Architecture. The walls are commonly experimented feature in aesthetics with several arrangement and patterns. The walls allow a controlled flow of air and light into the interior space. The Jali walls increase the surface area and mass of the facade to cool much of the breeze in the passage.
traditional elements
The columns in Indian Architecture are widely ornated feature in the building. Though the composition in the building is plain and simple, the randomness of mosaic chips give a pretty ornamentation, while the composition gives a salient uniformity. The chips on the column are of blue mosaic tiles giving contrast to the yellow walls. The columns mark the edge and give a proper direction for circulation.

Landscaping is an indiscrete feature of the site within and around the building. A large range of trees and shrubs can be found; some have medical significance. The rear garden is a dense pact of numerous trees of medium height making it completely distinct from city enviroment. Each plant has a name plate with relevant information for the vistors. A few species of birds can also be found with no aviary to bound.

root zone water treatment
Conservation of water was a prime concern for this project. Water generated in the building is treated by Root Zone Treatment Plant - a process to treat waste water through a biological mechanism. The treated water is used for irrigation requirements, within the campus.

contour trenching
Prevention of soil erosion is achieved by contour trenching and planting of vegetation. The valuable topsoil has been retained and impervious surfaces are kept to minimum, so as to prevent erosion by run off. Sedimentation chambers and grass swales ensure that the storm water run-off does not carry away the soil beyond the site limits.

wind towers
A Windcatcher, Windscoop or Badgir is a traditional Persian architectural element to create natural ventilation in buildings. Cooling upto 8oC, the wind towers supply to the AHUs, substantially reducing the load on the air conditioning system . A heavily insulated roof further reduces the cooling load.
