Govenrment of India Initiative - Basic Services to the Urban Poor

As per 2001 census, 61.8 million people live in Indian slums. The ever increasing number of slum dwellers causes tremendous pressure on urban basic services and infrastructure.To cope up with the rapid urban growth, the Government of India initiated a mission called Basic Services to the Urban Poor (BSUP) under the Jawahar Lal Nehru NAtional Urban Renewal Mission (JNNURM).


The main aim of the mission is to attain a reform driven outlook that can achieve fast track, planned development of some identified cities with a focus on efficiency in urban infrastructure/ services delivery mechanism, community participation and accountability of Urban Local Bodies towards citizens. It is planned with a framework for a period of 20-25 years with 5 yearly updates. A city development plan is required before the city can access mission funds.


It focuses on integrated development of basic services (security of tenure at affordable prices, improved housing, water supply, sanitation, and delivery through convergence  of other already existing universal services of the government for education, health and social security). Providing housing near place of occupation is also aimed at.


The financing pattern has been formulated as under:


Category of cities                                                           Grant                              State/ ULB/ 
                                                                             Central Government         Parastatal share, 

including 

Beneficiary Contribution

Cities with 4 million + (2001 census)                            50%                                        50%
Cities with 1-4 million (2001 census)                            50%                                        50%
Cities/towns in North East states & J&K                       90%                                        10%
Other cities                                                                 80%                                        20%


It has been decided that housing should not be provided free to the beneficiaries by the state government. A minimum of 12% contribution has to come up from them, which in case of SC/ST/ BC/OBC/PH and other weaker sections is 10%.


The cities selected under the mission are as follows:


Delhi, Greater Mumbai, Ahmedabad, Bangalore, Chennai, Kolkata, Hyderabad, Patna, Faridabad, Bhopal, Ludhiana, Jaipur, Lucknow, Madurai, Nashik, Pune, Cochin, Varanasi, Agra, Amritsar, Visakhapatnam, Vadodara, Surat, Kanpur, Nagpur, Coimbatore, Meerut, Jabalpur, Jamshedpur, Asansol, Allahabad, Vijayawada, Rajkot, Dhanbad, Indore, Guwahati, Itanagar, Jammu, Raipur, Panaji Shimla, Ranchi, Thiruvanantpuram, Imphal, Shillong, Aizawal, Kohima, Bhubaneshwar, Gangok, Agartala, Dehradun, Bodh Gaya, Ujjain, Puri, Ajmer-Pushkar, Nainital, Mysore, Pondicherry, Chandigarh, Srinagar, Haridwar, Mathura, Nanded.

Modular and Multifunctional Spaces

The concept of modular and multifunctional spaces has been a well established design aspect. But see how architect Gary Chang from Hong Kong took it to the next level by transforming his 344 sq. ft. apartment into 24 different designs just by sliding panels and walls. He converts his living space into multi-utility zones as per the need of the day.

How can we use this in the Indian context of slums? So we went into some slum houses and studied the interiors. Very interestingly people use every cubic meter of space available to them. Hence the challenge of modularity of our context lies in the modular utilization of 3D space. For example, the washing space is not in use all the time. Very interestingly some of the slum houses had a washing area so small that a person can only crawl in to use it. Others had not so well demarcated washing areas and hence all other members of the house will go out when someone wanted to take a bath.

TATA Housing Development Company and affordable housing

"We plan to invest Rs 2,500-3,000 crore in 2011-12 to develop existing and new projects in the affordable housing segment," Tata Housing Development Company managing director Brotin Banerjee said in March 2011. 


To achieve this, Tata Housing has formed a subsidiary Smart Value Homes to develop affordable houses in the price range of Rs 5-35 lakh. New Haven – the hill township at Vasind, is expected to offer 1,252 apartments including 2 BHK and 3 BHK homes starting at Rs. 15 lacs to 35 lacs INR with a minimum size of 638 sq.ft. Vasind is a developing industrial area and close to Kalyan. It will be constructed under the guidance of Indian Green Building council so as to achieve minimal impact on the environment. It has also collaborated with Micro Housing Finance Corporation to provide the informal segment (first time house owners and self-employed) of buyers with finance opportunities. A tie up with SBI and HDFC has been done to provide the formal segment with finance. The house allotment will be done on a lottery basis and some flats have been reserved exclusively for 1st time buyers.


A comparison between the prices offered by VBHC (as discussed in the previous blog) and Tata Housing shows that both the companies are offering similar prices. After having experienced the innovation that TATA Nano marked in, the nano in the habitat domain seams still to be far fetched. Or is this price tag already the housing nano?

Affordable Habitat Models - Value and Budget Housing Corporation and Janadhar Constructions Pvt. Ltd.

Several initiatives have been taken by private entrepreneurs towards building affordable houses for Indian low income groups. Value and Budget Housing Corporation is one of such initiatives. The company tries to streamline the construction sector activities through efficient management techniques by drawing its inspiration from industrial production philosophy. Construction techniques like Engineered Metal Forming Systems for Concreting are used. This technique helps in building an entire house (inclusive of construction, design, specification, planning, budgeting, execution) in one day. Building Information Modeling and 3 D modeling techniques help in planning the processes so as to avoid any clashes between architectural , electrical, plumbing and structural design in the pre-construction phase itself. Hence various models can be drawn out from which the most optimum can be selected. Thus VBHC can deliver apartments to its clients within 12 months of booking.

The offer price of a VBHC house is from 6.8 to 13.9 Lakhs INR for a studio, 1 BHK and 2 BHK apartment where the caret area varies from 251 - 481 sq. ft. Since land prices are a big hurdle, VBHC has opted to construct houses that are minimum ground + 9 and located in sub-urbs or outskirts of cities like Bangalore, Mumbai, NCR, etc. VBHC has decided to work on profit levels that is common in industrial products, 10-20%, rather than the construction industry standard of almost 100%.


Janaadhar Constructions Pvt. Ltd., on the other hand, is floated by Janalakshmi Social Services, a not-for-profit entity. It aims at blending marketing principles with not-for-profit spirit. They offer 1 BHK and 2 BHK apartments of 400 and 615 sq. ft at 5 Lakhs INR and above. It is supported by Sterling Developers Private Limited, a leading name in the construction industry for high - end premium housing projects. Hence it presents a unique blend of partners to this venture. Janaadhar is also building housing project in outskirts of Bangalore to reduce the land price.


Both the companies have also initiated a financing scheme for the customers since they realized that the Indian banking sector does not lend to non-salary holders. But the ground reality of most customers of these companies is that they are self-employed. They are bent towards providing good living conditions by incorporating amenities like schools to the residents too.


The basic principle behind the organization of both the companies is to make housing affordable through streamlined construction management, efficient construction techniques and financial assistance. Any brief visit to a slum or a chawl presents another very basic requirement of the inhabitant there...the community spaces and the social life. These aspects have not been considered in both the cases. The other ignored aspect is the fact that the slums provide a living and work space together, hence the term habitat. The true impact of these socio-economic indifference of the two projects on its residents can be assessed only when they actually get inhabited.

Social Innovations and Affordable Habitat

Think of a world without slums! The city of Indore can now think of it, thanks to Mr. Himanshu Parikh.


Mr. Himanshu Parikh focuses on urban planning, infrastructural development and environmental upgrading. He developed a new holistic concept for slum development called slum networking. It addresses a range of facilities like road and footpaths, storm water drainage, sanitation and sewerage, water supply, earthworks and soft landscaping, street lighting, solid waste management. It is achieved through minimal donor funding and maximum community participation. It uses an efficient microcredit system.


Mr. Parikh's study of slum development revealed that slums develop along the natural drainage paths. Hence he designed drainage and sewerage at low cost by making them follow the topology of the area. Thus the cheapest way to provide sewerage to a city is to build major sewers through the slums and then connect the higher (and usually richer) areas of the city to them. This scheme helps to secure funds from the local and national government for the construction of the drainage. Some donor money also comes in. The cost savings give leverage to the local government to provide tenure to slum dwellers who then willingly invest in the enrichment of their property due to the sense of security built up. The city of Indore saw a mind boggling upgradation of slums within two years and the slums are no longer recognizable as slums.

Inspirations for Green Habitat

1. Cheap water treatment - the river's way
Rivers clean their water all the time by a combination of gravity and a swirling motion, called the vortex. Watreco is using a simple vortex generator to remove air and lime from water. Thus producing bacteria free and soft water. Concrete when formed in this water performs much better. Less water is required for irrigation. Ponds and lakes can be cleaned this way.

2. Glass as a building material
Glass as a building material is extensively common in modern architecture. But producing glass is a very energy intensive process. On the other hand, a huge pile of glass ends up in the landfills. Recycling of glass is also very expensive.


Heating up a blend of glass with carbon dioxide injection creates glass foam which is light but very hard material. It has outstanding compresive strength, an ideal abrasive, a powerful insulation, excellant sound barrier, allows no water seepage and provides a hydroponic growth medium. Hence it can be an excellant building material. Pittsburgh Corning is doing the same.

Building Material - http://pittsburghcorning.com/default.aspx
Abrasives - http://www.goearthstone.com/earthstone.asp


They are being used as pre-fab foundations, walls, roofs (structural as well as insulation). No water permeates through them, no vermin, no fungi and insulative properties outweighs existing materials in cost and performance.

Thus it creates a carbon sequestering construction process.


3. Buildings inspired by termites
Termites control air and humidity in their nest through laws of physics. Their meticulous structure design helps them to constantly maintain a temperature of 27 degree C and 61% humidity. The height of the mound, the length and width of the air channels, the position towards the sun and the choice of building materials together create this genius.

A swedish architect, Anders Nyquist, motivated a team to design a mathematical model that built on the termite mound principles and can offer predictable results to building designers. The technique was applied to the construction of Laggarberg School in Timara by Sundsvall.

4. Build like a zebra
A zebra with its black and white strips is very efficient in maintaining its body temperature through air circulation. 


How can this be used in heating and cooling of architectural space?


The Energy and Resource Institute, India while building their new office building used similar inspirations and hence operate without the need for air conditioning. On the south, the building has a double wall, which is made of black kappa stone on the exterior. Thus the heated air rises up and forces convectional currents from the north.

5. Plant air purifiers

ANDREA is a living plant purifier created by a French designer, Mathieu Lehanneur. It purifies air by enhancing the metabolic activities of a plant. Although it can use all plant species, some of them are more effective. For example, peace lilly, madagascar dragon tree, etc.
