ABSTRACT The thesis proposes to reinterpret the design of Chhattisgarh Vidhan Sabha Complex at Naya Raipur. It aims at developing a complex which reflects democratic behavior in its true sense along with making it an Icon for the state in a modernist approach. This intent then further drives the thesis to en-quire upon some research areas. First area inquires about the history and development of Chhattisgarh as a state. Second one looks at the emergence of Governance in human civilization. The third aspect focuses on the architectural representation of ideologies and political beliefs and understanding relevant models of democratic institutions in place through case studies. The Vidhan Sabha complex is in the centre of the Naya Raipur city which has the capability to lead the future developments in and around the state. The learnings and inferences from the research and the studies resulted in some design directives and concept development. The design conceptually responds to the geographical division of Chhattisgarh, it’s culture and tribes and to the democratic nature of the institution. It is an open plan type design with segregated components keeping in mind the humanized scale of the overall built environment. The key drivers are the public participation and de-institutional character. The sectional interpretation highlights the democratic character of Vidhan Sabha. Public holds the centre stage in this design.
PART
A
INVESTIGATION
INTRODUCTION With the formation of the Chhattisgarh, the state demanded for a new capitol which could reflect the rich tribal culture, flora and fauna of the state. The state of Chhattisgarh has always been very vibrant in terms of it’s tribal culture, forests and rich mineral ores. To cherish it’s true identity and to project itself as self sufficient entity, Chhattisgarh was formed on 1st November, 2000.
Assembly Buildings in India
The assembly buildings in India are mostly following the western idea of depicting democratic institution. India happens to be world’s largest democracy but the incorporation of its true regional essence in its architecture is still questionable. Although efforts have been made post Independence to create the Indian architectural expression of democratic institution but so far, the representation of the region is still missing.
What would be the Indian or more precisely Chhattisgarhian language of architecture of democratic institution? How can it respond to the rich culture and traditions of the state in a modernist way?
PROJECT BACKGROUND

PROPOSITION
PROJECT
The thesis re-imagines the architecture of an assembly building in terms of its democratic behavior. It also intends to explore upon the principles of critical regionalism along with establishing the democratic institutions as an Icon for the state of Chhattisgarh in a modernist way in keeping mind the existing models in place.
To manifest the proposition the project re-imagines the design of the Chhattisgarh Vidhan Sabha complex which happens to be the part of capitol complex of Nava Raipur where already two blocks namely- Indravati (Directorate) and Mahanadi (Secretariat) are in place. The Vidhan Sabha block is also part of the existing capitol complex.
OPPORTUNITY The project intends to create an institution of democracy which would reflect Chhattisgarh’s true identity. Chhattisgarh state since it’s separation has been suffering from this term called Backward state. This thesis tries to break this image of the state. The existing planning and development of Naya Raipur adds to the intent of the project.
PROPOSITION
Various designs have been proposed for the project of Vidhan Sabha having an increased capacity in keeping mind the future expansion of the constituencies the state. The current proposal for vidhan sabha is proposed for 150 MLA seats. The major focus in the new design for the assembly building is on the reflection of the state’s true identity with an modernist approach. This project would also govern the idea of development in the upcoming projects of Naya Raipur.

NAYA RAIPUR 4TH PLANNED CITY OF INDIA The Naya Raipur is spread in around 250 sq.km of area located around 17 km towards the south-east of the old Raipur city. It is developed as a 4th planned city of India after Chandigarh, Bhuvaneshwar and Gandhinagar. Through the model of Naya Raipur as its capitol city, the state has an opportunity to establish itself as a an effective model of development in a modern setting along with glorifying its rich heritage and culture.

ABOUT CHHATTISGARH
ABOUT REPRESENTATION
GEOGRAPHY & FORMATION
Chhattisgarh came from the words Chhattis and Garh meaning 36 forts. The area of Chhattisgarh (not the current political state) constituted of 36 forts which were the anchor points of the state. These could be seen as the strongholds of the area.
ARCHITECTURAL STUDY
ABOUT GOVERNENCE EMERGENCE AND THEORIES
The theory of Social Contract describes the relation between the state over the common public in a form of contract, to establish systematic and safe well being of every individual under the authority of the state.
The interaction of public with the parliament building seems not very participatory. The scale of the building is also very dominating.
Northern Region 18 Garhs The buildings sits on a hilly site and the public entry into the building is from the topmost side of the hill. It depicts that the building overlooks the
Mahanadi River
Shivnath River
Southern Region 18 Garhs
The building is very consolidated and is part of Mumbai’s high rise locality near the Nariman Point. The building is highly secured and isolated.
Junction of Shivnath and Mahanadi
This building could be seen as more democratic in nature. The interaction of the building with the public is such that the public can access the RESEARCH AREAS

VIDHAN BHAWAN Bhopal, Madhya Pradesh
SCOTTISH PARLIAMENT Edinburgh, Scotland
The design responds towards critical regionalism. Use of landscaping, water and courtyards creates a micro-climate. Hugely spanned spaces provides a grand nature to the building but travel distance increases. Also, this wide complex demands more security staff.
Publicness of building is one of the remarkable things. The scale has been humanized at almost every component of the building. It has too many unused corner spaces or negative spaces. To create something as abstract modernist as this offers a huge criticism.
VIDHAN BHAVAN Mumbai, Maharashtra
WELSH PARLIAMENT Cardiff, Wales
The building is a democratic institution but unfortunately it doesn’t have any public function. The functions being stacked vertically are highly dependable on the mechanical systems of movement. The security load gets reduced by significant amount.
Public functions are well incorporated in the design. The multipurpose spaces in the building makes it more informal and humanize the ambience. Building demands for the high level of security. Response to the regional material pallette using grey slate for flooring and walls.

USER GROUPS
AREA DISTRIBUTION Distribution of total built up area of around 17,000 sq.m. constitutes of all the programmatic components distributed around the site. The pie chart shows the percentage wise distribution of all the components.
MLAs
VIPs
Includes members elected from individual legislative constituencies of the state along with their PA and other regular staff.
This includes the speaker, deputy speaker, chief minister, their guests and first class government officers and visitors to the VS.
Administration & Staff
Public Visitors
This is the regular user group responsible for the functioning of VS procedures and VS campus. They function in non session days too.
It includes the common public and journalists visiting the VS campus after issuing a pass or being invited by any member of VS.
PROGRAM COMPONENTS

FUNCTIONAL RELATIONSHIP
User Groups
Major functions are formed with direct or mixed occupancy of these four user groups. Segregation of these with the effective design would reduce the security load.

SITE AND SPANS
THE PUBLIC AXIS
VEHICULAR ACCESS
Huge Spans and Building Placement The existing buildings on the master plan of Capitol Complex are placed at very huge distances from each other. The scale of buildings gets diminished in huge land pieces.
Visibility from the Public End Certain element of building should incorporate a decent height which would make it’s presence and would attract public from the opposite end.
REGIONAL ESSENCE
The Big Idea behind the designing of the assembly building should reflect the regional identity. Critical regionalism should be reflected through the design.
Master Planning of Capitol Complex The Capitol Complex has a public pedestrian axis in the middle dividing the Secretariat and the Directorate blocks. The design should try to extend the axis and draw public to this iconic institution of democracy.
TRIBAL CULTURE
The tribal culture is the in the nerves of Chhattisgarh and the assembly building should in a way bring that essence into the design.
DESIGN DETERMINANTS

Connecting Edges Public edge would be utilized by the public visitors and administration people whereas the Private edge would be used by MLAs and VIPs. The design should connect the edges creating a loop for the internal circulation.
POWER AND PUBLIC
The learnings from sectional study of several democratic institutions should reflect in the design. Section should reflect the democratic relation between public and power.
SHAPE OF CHHATTISGARH
Distribution of 36 Garhs The geographical arrangement of these 36 Garhs was such that they were divided by the river Shivnath and Mahanadi into 3 halves containing 18 Garhs each.
Mathematical Interpretation of Chhattisgarh The word Chhattisgarh came from junction of two words: Chhattis and Garh. The word Chhattis means the no. 36 which happens to be a mathematical square of no. 6.
36 Garh (6 x 6) Garh Representation of Garh: Triangle A garh is represented by a Triangle because a triangle is the smallest stable 2D shape.
18 Garhs Mahanadi River
Cluster of 6 Garhs: Hexagon The 6 Garhs (Triangles) when arranged geometrically, form a Hexagon.
A Garh
6 x (6 Garh)
Shivnath River
18 Garhs
Chhattisgarh: 6 Clusters of Hexagon The interpretation of the overall form of chhattisgarh then becomes combination of 6 Hexagons which inturn have 36 Triangles (Garhs) in total.
Interpretation in Design Based on the geographical understanding of Chhattisgarh, the shape of Chhattisgarh derived as a concept also modified. Introduction of water body represents the division of 18 Triangles in each half.
The Final Shape Deriving from above interpretations and arrangements, the shape which could geometrically symbolize Chhattisgarh is developed.

The Final Conceptual Shape
INTERACTION OF POWER AND PUBLIC
Here the relation is less democratic and the power is more secretive in nature. The citizen’s participation with the built is minimum.
Here the relation is too much democratic and the public is all over the power. The state’s identity and image is not justified.
To create a balanced situation where the public and power participate in a truely democratic way and state’s identity is also justified. DESIGN CONCEPTS

ZONING
TREE AS A SYMBOL
Interpretation from Tribal Culture & Forests The tribal culture being at the heart of Chhattisgarh is very close to the trees both physically and culturally. So, this symbol of their belief reflects as an element of design in the Vidhan Sabha complex. Idea Behind Zoning The basic segregation of functions is based on the access of different user groups to the Assembly. Lower end being the public end has library and auditorium attached to it. The upper end being the private end has all the offices and meeting halls. Assembly holds the center stage.
MASSING AND PLACEMENT
Volumetric Zoning Based on the Program Analysis, the assembly hall holds the main attention in the design and hence this also gets reflected in the volumetric zoning of the components. The Assembly block at the center is volumetrically dominant over the other blocks.

PASSIVE STRATEGIES
PHOTOVOLTAIC PANELS
Photovoltaic panels which are often known as solar panels consists of photovoltaic cells arranged in a manner to form a panel structure with certain amount of capacity of electricity generation. These smaller modules use solar rays to generate power through photovoltaic effect. Building integrated Photovoltaic (BIPV) system functions on integrating these PV panels into the building components such as roof or facade which also results in saving cost for building materials for envelope.
MOISTURE SENSOR SYSTEM
Soil moisture sensors estimate the volumetric water content in the active root zone. The Irrigation controllers only switch on when the moisture level gets below the mandatory level for any specific plant species. By regulating the existing irrigation system as per the moisture content in the soil, the water can be saved by a huge amount if installed properly. SUSTAINABILITY

THESIS RESPONSE The thesis revolves around two major issues and consequently tries to propose a solution to them through a proposed design. The issue: Looking at the current political scenario in our country, we find that the democratic identity becomes questionable more often. Although the process is ever changing and we as a system adapt to those changes. One way in which Architecture contributes to this process is through expression of these democratic institutions and its impression on the decision makers. The western or more institutional influence on democratic institutions in our country is still visible. The grand Architecture of such places make them more of a ‘Castle’ which gives a sense of power to the rulers which apparently starts diminishing the connection with the public. States like Chhattisgarh have a huge percentage of its citizens from rural areas. Despite the state’s developing image in modern terms which is more economically driven, the state suffers from the issues like Naxalism and Maoism in it’s far untouched areas. Chhattisgarh has got great resources, flora and fauna but still somehow its representation in the outer world lacks the true identity. This raises a question regarding the communication gap between the representatives and citizens even after 21 years and 5 legislative terms since the formation of state. How this thesis engaged with these issues: This thesis on Vidhan Sabha of Chhattisgarh after questioning the above issues, proposes a design which celebrates the state’s identity through reflection of its culture and geography in its Architecture while keeping it as grounded as possible. The humanized scale and open type planning breaks the castle and brings out the pure colours of democracy. It’s more De-institutional character brings out the regional essence of the state. The site is located in the centre of Naya Raipur which is planned on the foundation of that vision which could project the state’s developing image in front of everyone. Through its planning and design, Vidhan Sabha brings out the public into the design and attempts to make it more participatory. Conclusion: The change is everlasting. Our democracy is changing and so is the relationship between power and public. Hence is changing the Architecture of these institutions of power. We as an architect are the ‘Agents of Change’ where we respond to the political setting and to the need of time with a vision to create spaces which could add to this change positively.
