1.1: Synopsis Projections show that due to urbanisation, 50% of world’s population will be residing in urban areas by 2050. This is a milestone in the history of human settlement. We all know the importance of a strong foundation for a strong superstructure. In order to be prepared for this milestone, rural development will provide us with the needed foundation for the urban development of this scale. As per 2011 census, about 70% of India’s population resides in rural areas. I take this opportunity of this thesis to research in the direction of sustainable architecture for rural Birbhum district of West Bengal, where the site for a centre for Mallarpur Nai Suva is located. This non- profit organisation works for the welfare of Santhal communities of this region. The site is immensely rich in resources like laterite soil, basalt stone, huge solar energy and good and skilled craftsmanship among others. These opportunities have been harnessed in the project and properly translated in the architecture of the project. This facility for the community has been designed to cater for decades to come. And it will also inspire the local community to adopt alternative construction technology for their personal construction projects.

1.3: Rural Architecture in 21st century India With 68% (Census 2011) of India’s population, rural India is very diverse and complex in terms of people, their power dynamics, socio-cultural and religious patterns, economic and political considerations, and caste and gender issues. These relationships play a very important role in the production of architecture in these regions. In developing countries like India, architecture is still made by people: skilled craftsmen, masons, carpenters and labour.
We trained professionals in construction industry are so intensely immersed in the landscape and skyline of the cities that we fail to acknowledge the need of our service in rural areas. They are the foundation are supporting systems for these ever growing cities and megapolis. India is a vast subcontinent with lakhs of villages spread across its length and breadth. And these cities emerge here and there in this network. We have to admit that the overemphasis of urban demands have forced the negligence to the state of Indian villages. ‘India lives in the past and the future we live 2500 years of history together’ – Khosla. R (1987) Figure 1 Typical street view in Mallarpur, conjuncture of vernacular and contemporary architecture (Source: Author)
When we think of villages, we think of it as primitive and fundamental as we are raised in this modern civilisation Nai Suva Centre

and environment. The villages have enjoyed a kind of isolation, which is a blessing in disguise, and have been thus able to preserve a tradition handed down from times immemorial. It is very easy to get trapped in the romanticism of these materials and that is where the architect needs have the clarity of thought to understand what should be done.
Rural India is at a crucial juncture of time, where, if not guided properly, we could lose its diversity and knowledge forever to the homogenising qualities of globalisation and free-market capitalism. When an architect goes into a settlement here to study it, it is important that one looks at it beyond a museum exhibit. We have to try to put ourselves in that context and time to understand why things were like this. Spaces here are very functional and practical and every detail has a reason. We have to put ourselves in that situation and try to figure it out. This is linked to materials, technologies, spaces and lifestyles. Often, studies of indigenous architecture do not move beyond this stage, as they are dubbed ‘vernacular’ or of the poor and not in tune with our times. Concurrently, it is equally of importance to not get stuck in the past. Things were done in the past in certain way as it made the most sense at that time. Yes, we must observe, document and learn from it; but not all of it may be applicable in this time period and that is where an architect has to be judicious to know what
aspects of indigenous architecture to take forward and what to leave behind.
The treatment of rural areas same as that of the suburban areas has depleted the potential of harnessing the rural energies. The proper understanding of the rural landscape should be the priority before taking any decisions. We have to proceed with great caution in our attempts to improve upon the villages, for once we destroy the villages, and they will be lost forever. One cannot, and should not, come into this landscape with preconceived notions of architecture and design like the ones propagated in architecture schools throughout the country. This process of research and discovery is exhaustive, time-consuming and requires an investment of time and energy from the architect to make it successful. Only then can we get an architecture that is true of the people, by the people and for the people.
“In any case, whoever is entrusted with the problem of solving the difficulties connected with evolving a rural architectural expression must be absolutely earnest, a kind of dedicated soul, in love with, and having sympathy for the village. There is a tremendous scope for work in this direction. But the man from the city, privileged as he is, must draw inspiration from the villages and must identify Nai Suva Centre
7
himself with the village, with his ideas of life and living, before trying to improve upon them.” (Rahman, H.) To spread the awareness and impact of well-designed and sustainable architecture to suit the rural landscape, pilot projects are required. Generally, a public building used by the whole community is the best project to demonstrate and educate them the suitable building skill. The involvement of the community to build a project for the community works in favour of the project in terms of the acceptance of the new vocabulary of building technology. The experience and the knowledge gained in the public building gets reflected and amplified in the personal buildings of the community engaged with. It starts a chain of knowledge transfer and sustainable growth. The concept of capacity building centre or a community centre creates a strong connection and ownership towards the structure. This structure would then help and sustain several self- help groups (SHGs) which strengthens and supports the local economy. The economic factor in the construction of any project for a non-profit organisation is of utmost importance. So, involving the local community in the process and making them responsible stakeholders creates an opportunity of “shramdaan” in exchange for training and skilling of local people for an employment opportunity. Also, the judicious and sustainable way of building techniques,
vernacular methods of that area and reinterpreting and evolving the use of materials leads to reasonable building costs.
1.4: Thesis Proposition 70% of India’s population residing in rural areas, are building and changing the landscape of the nation. The pace of change from vernacular techniques of building to the contemporary construction techniques is very fast. This arises from aspirations of the people. It is the role of the architects to guide the scene of the changing landscape. The third- tier towns are in a toddler stage from where they are at the brink of taking any shape which they are exposed to. And, the public buildings prove to be a great canvas to set an example for the communities to expose to the alternate sustainable construction techniques. The binding factor for the community at large are institutions for collective welfare. In this case helping a non-profit organization to set up a rural community centre is a challenge in terms of economics and acceptability.

2.1.1: Architecture for Community Designing for a community is a complex process than just designing a structure in a site. It requires an in depth understanding of the local community structure, ecosystem, economical model and the beliefs and aspirations of the community as a whole. To understand the community, there are mainly two ways architects can use: 1. Doing a study of the local vernacular architecture, building techniques, material palette etc. Architect Siddharth Menon, has under taken study of building techniques in rural areas in different states of India before using the improvised techniques in his projects.

Regional dialect-Yakshi learning Centre, Telangana and Rural community Centre for the organization Anubhuti Seva Samiti in rural Uttar Pradesh were done using mud and local materials. His study addressed the use of locally available materials like mud, bamboo, and stone, with labor-intensive building techniques and community-based craftsmanship in this swiftly globalizing and homogenizing rural India, stating examples from across the country pointing out the unique ways in which building techniques are adapted to make them more contextually relevant.

2. Conducting workshops with the community to understand the aspirations of the people in a collaborative manner.
‘Workshop Architecture’, a student initiative in partnership with the Indian Trust for Rural Heritage and Development (ITRHD) and the British Council did a school project in Hariharpur village in Uttar Pradesh. They conducted a series of workshops with the villagers, teachers and the mothers of the school children to come up with the masterplan and the final design. Together with the teachers of the school, parents, local artisans and craftspeople, the design and construction of the school was an opportunity to learn from vernacular building methods, reinterpreting and evolving them to create a building which addresses today’s needs and aspirations.

2.1.2: Understanding the ‘NGO: Mallarpur Nai Suva’ About Mallarpur Naisuva Mallarpur Naisuva (MNS) is an informal group of young people inspired with the spirit of social work into a fullfledged NGO engaged in various rural development activities. It was in 1985-86 that these young men, instead of spending their leisure times by playing cards only, tried their hands in social work, being inspired by their mentors – late Dr. Ashok Pathak, a doctor practicing in the village of Mallarpur and Shri Sadhan Sinha, a National Service Volunteer of Nehru Yuba Kendra at Birbhum, West Bengal. Today 75 youth clubs are partners of Naisuva in its various activities and in 2008 received the prestigious Netaji Subhas Chandra Basu award from the Dept. of Consumer Affairs & Fare Business Practice, Government of West Bengal. We have also received Award from NABARD in Promotion of Rural Entrepreneurship in the year 2009. Their mission is to build up a cadre of socially conscious youth in the field of community development through capacity building.
Aims and Objectives of the NGO • To initiate the awakening process. • To build up the people's organization and the capacities of the people. • To strengthen women in the expression of their full potential and rightful place in the society. • To try integrated and sustainable models of community health and rural development using, people participatory approaches. • To develop the technical skills for the people of the poorer section for their lifestyle through maximum utilization of the local resources. • To provide education and other alternatives for integrated development of the children, especially the girl child.
Area of Operation The development activities of MNS are spread over four blocks of Birbhum district, namely, Mayureswar I, Mayureswar II, Rampurhat I, and Rampurhat II in West Bengal, India.

Target Groups
2.1.3: Conclusion
The target groups of MNS's development activities are economically poor people, women and children, child labour, SC, ST, victims of calamities, people with disabilities and youth.
This project is beyond an architectural exercise. It is an opportunity to create a self-sufficient and sustainable ecosystem of culture, economy and resource management. The required outcome will only be achieved by having an empathy with the community, understanding the needs of the project and its users. And also predict the possible demands in the coming future. The first steps will be to understand the site, mark the resources and skill available which will be the potential opportunities. Conducting workshops with the user groups will help in identifying the needs and drafting a basic design for this community facility. The way of living of the Santhal communities and the functioning and aspirations of the non-profit organisation has to be embedded into a single goal for the project.

Gross floor area: 3,053 m2
This project is a capacity building run by an NGO. The context is very similar as it is adjacent to paddy fields in warm-humid climate of Bangladesh. It received Aga Khan Award for Architecture 2016 which made this project popular and directed a new dimensions of rural institutional architecture.
The Centre was created to train staff of an NGO working with people inhabiting nearby chars, or riverine islands. Offices, a library, meeting rooms, and prayer and tea rooms are included in pavilion-like buildings surrounded by courts and pools. The Centre is also rented out for meetings, training, and conferences for income generation. Site planning
Figure 17: Friendship Centre, Bangladesh (Source: akdn.org)
To prevent flooding, the Friendship Centre is built directly on the low land and the entire site is protected with an embankment which could be built and maintained for much less. Divided into two parts- public and residential The ‘Ka’ Block contains the reception pavilion, offices, library, training/conference rooms and pavilions, a prayer space and a small ‘cha-shop’. Between the two blocks are large tanks to collect rainwater. Nai Suva Centre

4.3 Conclusions The study of the functional components and the site study concludes the following design directives:
There are different components of the project which can be arranged in the hierarchy of public nature to private nature. The components like health center and school needs and buffer from the main road. Whereas the residential components needs filtered access to its premise. The health center needs a designated entrance. The workshop and the community kitchen requires separate service yards. The adjacency diagram shows the links between the components. The site analysis shows that the potential entry points, and the placement of the built components. Due to the location of the petrol pump and the ashram, the blocks has to be pushed into the paddy field end Due to the highway, there is a setback of 13m required on the road edge. The wind direction is a major factor for orientation of blocks in this warm- humid climate. The natural hydrology of the site helps in identified the suitable spaces for surface water collection.

5.1: Structural Systems Structures
for landscaping later, the soil dug from the site itself can be used in construction.
The choice of materials and construction technology is determined by the following factors:
Maini, S. (2002) proves that adding 2% to 5% of cement and cattle urine as stabilizers increases the strength.
1. Low embodied energy of materials and sustainable construction technologies in terms of resource usage and environmental impacts.
Using terracotta tiles and basalt stone on the outer face of custom made CSEB makes it more durable.
2. Economical and employing local labours and craftsmen and keeping the capital within the community
Columns and Beams: Custom shaped CSEB
3. Social and cultural acceptance of the structure.
Foundations: Basalt stone The basalt stone quarries in Baramasai and Pachami Stone mines are in the range of 20km from the site. The hardness of stones is very good and can be used in construction. The cost of transportation will be also less.
Walls: Compressed Stabilised Earth Blocks (CSEB) The soil available in the region is laterite. Laterite are highly weathered soil. It contains variable amounts of iron oxide and aluminum. It is red or brown in color. It hardens quickly in air and becomes resistant to meteorological agents. After removing the fertile topsoil of the site and storing it

Window projection, shelves, water tanks: Ferro cement Doors and Windows: Poplar wood from populous trees (locally available) Structural system is load bearing walls with reinforced columns and beams. Slabs are compressive members with Ferro cement channels and funicular shells. The construction process is labour intensive and use local labours and craftsmen and creates opportunity in skilling of community and strengthening local economy.

5.2: Services Electrical: Energy source: Solar panels and biomass gasifier other than drawing from the grid. Efficiency of using biomass gasifier: Biomass gasifier as described by Majumdar, M. (2002) is fed by bio-degradable waste of the campus and the nearby agricultural lands. In a biomass gasifier this biomass is burnt efficiently. Any surplus energy that is generated can be used to recharge the battery bank. The battery bank is thus served by two sources of power, namely the photovoltaic panels and the gasifier. Figure 32: Biomass Gasifier (Source: TERIIN.org)
Daylighting: By optimizing the orientation and the width of the buildings, most spaces are day lit. Light shelves have been used to reflect light and the curved fibrocement channels spreads light evenly into the space.
Skylights have been used in the workshops to day lit the spaces. The classrooms are placed on the northern side to receive shadow less and glare free north light. The circulation is arranged in western and southern faces to create buffer.

Mechanical: The mechanical load of elevators are limited for economical purposes and the total number of stories are limited to four. For universal accessibility, ramps have been provided. Only Health Centre has elevators. Heating, Ventilation and Air Conditioning: Passive techniques are used: 1. Thermal Insulation: CSEB walls with rat trap bonds provide a lot of thermal Insulation. 2. Natural Ventilation: The orientation and alignment of the buildings along the wind direction naturally ventilates the spaces. The hot winds are passed through jaalis to make it cooler and is circulated by the corridors. 3. Thermal mass and evaporative cooling cannot be used in warm humid climate. Most spaces are cooled by these passive techniques. Solar chimney, Majumdar, M. (2002), is used to induce natural ventilation by the thermal-buoyancy effect. The structure of the chimney absorbs solar energy during the day, thereby heating the enclosed air within and causing it to rise. Thus air is drawn from the building into an open near the bottom of the chimney. The air exhausted from the house, through the chimney, is replaced by ambient air.

Earth air tunnel uses earth as a heat sink or a source for cooling/heating air in buried pipes or underground tunnels. Earth berming: earth sheltered building reduces infiltration of outside air and the additional thermal resistance of the surrounding earth considerably reduces the average thermal load shown by Majumdar, M. (2002).
Figure 34: Earth Air Tunnel (Source: TERI)
For cooling of specific areas of health centre and the office block, displacement ventilation is used.
Displacement ventilation: The solar chimney clubbed with earth air tunnel cools the spaces by displacement ventilation system. Where the cool air is supplied by the earth air tunnels.

Water sources: In the absence of any water supply from governing agencies, ground water becomes the most important water source. Rain water is harvested and collected to recharge ground water. Permeable paving surface and percolation pits are used to absorb rainwater. On site waste water is treated and recycled for flushing, landscaping, evaporative cooling. Waste water treatment: CSIR-NEERI’s technology of Phytorid waste water treatment is used in the project. It is very efficient, cost effective and low maintainace system. The total area required for the system is approximately 35 sq. m. for 20 m3/day. Figure 36: Phytorid System (Source: NEERI)
Safety Construction safety: the process of construction with the earth blocks are simple and safe to execute with minimal training required.
The corners are reinforced with vertical steel reinforcement. The lintel band and the floor bands anchors the structure.
Earthquake safety: The site is in earthquake zone III. The structure has load bearing cross walls and star shaped columns.
The custom made CSEB with jute diaphragm, provides additional strength to the walls. Nai Suva Centre
46
Fire safety: Adequate setbacks are provided around the building. Automatic Sprinkler System is to be used. A system of water pipes fitted with sprinkler heads at suitable intervals and heights and designed to actuate automatically, control and extinguish a fire by discharge of water. Naturally ventilated spaces with adequate open areas are provided. Fire staircases are placed at suitable areas. Sustainability GRIHA rating: The project uses several sustainable techniques to make efficient management of natural resources. As per the GRIHA rating system, this project aims to achieve 4 star or above rating. Also following ECBC standards makes the passive design techniques more efficient.

Chapter 6: SWOT Strength
The shape of the site in vey uniform with gentle slope. The site is rich in laterite soil The workmanship available is very skilled There is no major built structure to influence the design.
Weakness
The climate is warmhumid which has needs of good ventilation of the spaces The huge front setback pushes the built mass further into the site There are deferent kinds of functions which needs proper buffer space to function properly
Opportunity
The resources provides a chance to experiment the alternative technologies Earth air tunnels can be used as an experiment for this region The different components can work together to make a close loop of resources The paddy fields can be a source of fuel for biomass gasifier The huge solar power can be harnessed by solar kitchen.
Threats
The landscape is very different than an urban area. There is a chance of over densifying and overbuilding FAR and related bylaws can pose a threat to the design

The way the design developed: The axis was maintained throughout the stages The entrances of different components were oriented towards the plaza in order to enforce the axis The circulations in each block were wrapped around the courtyards The wide verandahs of 2.5m wide were maintained even they increased the total built up area. These verandahs help ventilating the spaces The built up area was drastically decreased in order to make the campus contextually synced. The pedestrian path were made legible and connected to the extents of the site The pedestrian entry was aligned to the main axis, which made it more prominent The parking was arranged to provide the required buffer from the highway. And also it gave the building the required setback from boundary line. The structural systems adopted are an experiment of the alternative technologies which have a potential here as the site is rich in resources.
Proposition revisited: 70% of India’s population residing in rural areas, are building and changing the landscape of the nation. The pace of change from vernacular techniques of building to the contemporary construction techniques is very fast. This arises from aspirations of the people. It is the role of the architects to guide the scene of the changing landscape. The third- tier towns are in a toddler stage from where they are at the brink of taking any shape which they are exposed to. And, the public buildings prove to be a great canvas to set an example for the communities to expose to the alternate sustainable construction techniques. The binding factor for the community at large are institutions for collective welfare. In this case helping a non-profit organization to set up a rural community centre is a challenge in terms of economics and acceptability. Providing a design proposal which focuses on harnessing the resources available in and around the site and using them in sustainable ways possible. This will inspire the community to adopt and invest in alternative technologies. Also, due to the empowerment of the public spaces in the project, the institute will gain the acceptability and feelings of ownership among the community. Nai Suva Centre

Design outcomes The final design was the derivation of the initial sketches of the arrangement of different components around courtyards. The axis leading to the multi-purpose hall remained as the connecting spine of all the components. The dormitories and the staff housing forms a separate residential area, separated from the public areas. The number of stories of each component changed as per the economics and functionality of the component.
