Tiny Homes to Meet Global Housing Crisis

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

More than 1 billion people around the world lack decent shelter. Of these, the majority live in urban areas, usually in slums and informal settlements (UN-HABITAT).

The world’s megacities – like Mumbai, India, where more than 22 million live in the metropolitan region – have to find a way to provide housing that is both affordable and does the minimum possible amount of harm to the environment.

About one-third of the world’s urban dwellers live in slums, and the United Nations estimates that the number of people living in such conditions will double by 2030 as a result of rapid urbanization in developing countries.

The fast pace of growth of India’s cities presents an enormous challenge: how to house so many people with dignity and to a good standard. India’s city slums are notorious and recently became the subject of the Oscar-winning film Slumdog Millionaire (http://www.slumdogmillionairemovie.co.uk/).

With a population of 1.2 billion, India needs to find 25 million homes a year to meet current demand, according to McKinsey and Co.

Housing prices have risen by 16 percent a year for the past four years. While the middle class – estimated at over 300 million people – has piled into high-end apartments and houses, it has been the country’s low-income people who have been frozen out of the option of quality homes.

The concept of targeting those at the ‘bottom of the pyramid’ (BOP) (http://en.wikipedia.org/wiki/The_Fortune_at_the_Bottom_of_the_Pyramid) has drawn attention to the estimated 23 million poor urban dwellers in India, and 180 million rural families, who have savings and want to own a home. Monitor India (http://www.monitor.com/in/) believes these people have annual earnings between US $1,400 and US $3,000.

The Indian manufacturing powerhouse Tata – which this year launched a BOP-focused car, the Tata Nano – has designed and is building, Nano Homes – small apartments outside Mumbai for US $8,600 (http://tatahousing.in/pages/home.php). It also hopes to expand to other major Indian cities as well.

The Nano homes are built on a modest scale: there are three sizes with the smallest measuring 67 square metres. They consist of a single room that doubles as a bedroom by night with a sink, bath and toilet behind a partition.

Criticisms include location – on the edges of major cities – where residents would have to commute long distances to get to their jobs.

Even so, Nano apartments are so popular buyers are being chosen by lottery.

“India’s housing crisis lies in the fact that the poor in the cities are priced out of the market,” Sundar Burra, an adviser to the Society for the Promotion of Area Resource Centre, a Mumbai-based housing rights organization, told Canada’s Globe and Mail newspaper.

“State supply of housing for the poor is woefully inadequate in relation to the need. Slums proliferate as a solution to this state of affairs.”

People can get a mortgage for the homes from Tata Home Finance.

Tata is not the only company targeting this market. India’s Matheran Realty (http://www.tmcity.in/) is building what it claim is India’s largest affordable housing project, Tanaji Malusare City, in the villages of Shirse and Akurle of Karjat (http://en.wikipedia.org/wiki/Karjat). The 15,000 homes would house 70,000 people and would sell for US $4,698.

Another developer, Godrej Properties (http://www.godrejproperties.com/), is building a BOP housing development outside the city of Ahmedabad with apartments costing US $11,749.

“(Property) developers have recognized that the real demand no longer lies in the premium segment and are opting to build smaller, no-frills apartments,” said Deepak Parekh of the Housing Development Finance Corporation (http://www.hdfcindia.com/).

It estimates the affordable housing market will be worth US$ 110 billion in India by 2013 and will account for 80 percent of India’s housing market.

“Affordable housing is not about box-sized, budget homes in far-flung places where there is no connectivity to workplaces and little surrounding infrastructure,” Parekh told HDFC’s shareholders. “Affordable housing has to be able to cut across all income segments and has to make economic sense in terms of proximity to the workplace.”

Colombian Architect Proving Strength and Beauty of Bamboo

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Fast-growing bamboo grass (http://en.wikipedia.org/wiki/Bamboo) has become a cause celebre amongst those looking for a sustainable and tough building material.

In the last five years, more and more construction projects have turned to bamboo. It has many advantages: it grows quickly, is super-strong yet also supple enough to bend in a hurricane or earthquake and has a high tensile strength (http://en.wikipedia.org/wiki/Ultimate_tensile_strength) equivalent to steel. It is, of course, green since it is grown in forests, and is cheap and plentiful in many countries of the South, especially across Asia and Latin America.

It is also aesthetically pleasing and makes beautiful structures with intricate patterns.

But despite all these advantages, it has been a hard sales job to get people to choose bamboo as a building material rather than traditional woods, steel or concrete. Many people wrongly think green means not strong. But as many a construction worker knows in Asia, where scaffolding made from bamboo is commonplace, it is tough and stands on its own.

Pioneers are working hard to prove bamboo deserves respect as a building material for a greener future.

Award-winning Colombian architect Simón Vélez has designed more than 200 bamboo buildings in Germany, France, the United States, Brazil, Mexico, China, Jamaica, Colombia, Panama, Ecuador, and India.

Vélez’s commissions are varied, and include a bridge for the Bob Marley Museum in Jamaica.

One of his recent projects is the Zócalo Nomadic Museum (http://en.wikipedia.org/wiki/Nomadic_Museum) in Mexico City. Another is the Crosswaters Ecolodge (http://www.asla.org/2010awards/370.html), the first ecotourism destination in China in the forests of Nankun Shan Mountain Reserve, Guangdong Province. For the Expo Hanover 2000, he designed and constructed a 2000-square-meter bamboo pavilion for ZERI (Zero Emissions
Research Initiative) (http://www.zeri.org/).

Vélez has developed pioneering joinery systems to connect bamboo poles together. This is a critical focus of innovation if bamboo structures are going to win people’s trust.

Based in Bogotá, Colombia, Vélez uses a well-trained crew to make his buildings and structures. This has the advantage of building expertise and a history of lessons learned from past successes and failures. That stability is a critical insight: many good ideas suffer from a lack of stability and longevity. He uses very simple, hand-drawn sketches on a single sheet of paper. He works with the peculiarities of the bamboo and does not treat it like wood: a common mistake.

To tackle the woeful lack of decent housing for the poor, he has developed a low-cost house that can be built by home-owners. It is highly resistant to earthquakes and is 60 square metres divided on two floors. It costs
around US $5,000 to make in Colombia.

Winner of the Prince Claus Fund (http://www.princeclausfund.org/en/index.html), Vélez’s work promotes sustainable development, introducing new ideas on ecological issues and questions. The Fund calls him an architect “whose aesthetic and technical innovations have considerably expanded the possibilities of bamboo as a building material, providing a challenge to prevailing architectural trends.”

With more than 1 billion people around the world lacking decent shelter, many see plentiful bamboo as a key part of the solution. Most people with poor quality housing live in urban areas, usually in slums and informal settlements (UN-HABITAT). Latin America has a serious shortage of adequate housing: in Colombia, 43 percent of the population needs decent housing; in Brazil, 45 percent; Peru, 53 percent.

The challenge is to provide good quality homes without significantly harming the environment – and with constrained budgets. Bamboo – cheap, strong, quickly renewable and beautiful – is an ideal solution to replace traditional wood lumber.

Bamboo is the fastest growing woody plant in the world, sometimes growing over 1 metre a day. Around the world, there are 1,000 species of bamboo. They grow in a wide variety of climates, from cold mountains to hot tropical regions.

Once called the “poor man’s timber” – a temporary building material to replace once there is more money – bamboo is now getting the respect it deserves. Bamboo for housing has a long history in Latin America, stretching back 4,500 years to ancient civilizations. In Asia, it has long been a traditional construction material. But most of the existing bamboo dwellings in Latin America are 50 to 100 years old.

The most popular species of bamboo used in South America is Guadua, which is known for being large, straight and attractive.

Thoughtful and methodical pioneers like Vélez are proving bamboo has a viable future as a building material that will tackle the housing needs of the world’s poor and the fast-growing cities of the South.

Filipino Architect wants to Transform Slum with New Plan

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

A clash is occurring across the global South over the future of urban planning and the ever-growing slums of the world’s megacities. This will be a decisive clash of visions: should cities flatten slums and relocate their residents, or work with slum dwellers, acknowledge the role they play in city economies and improve their lives with better dwellings?

As the world turned into a majority urban place in the 2000s, cities grew at a phenomenal rate. The cities of Africa and Asia are growing by a million people a week, according to some estimates. Megacities and sprawling slums will be the hallmarks of this new urban world, it seems. In sub-Saharan Africa, 72 percent of the population already lives in slum conditions.

The danger of building unsafe or makeshift homes can be seen in 2010’s devastating earthquake in Haiti, where many buildings collapsed, killing thousands.

One of the Philippines’ leading architects and urban planners,
Felino A. Palafox Jr. of Palafox Associates (www.palafoxassociates.com), is passionate about re-making the slums in his country’s capital, Manila. The city is prone to devastating and sometimes deadly flooding. Palafox believes the vulnerability of slum dwellings and poor urban planning are placing lives at risk.

“We can’t wait for another tragedy,” Palafox told the Philippine Daily Inquirer in 2010. “We have seen how an unprecedented volume of rainfall like what (storm) Ondoy had brought could prove too much for Metro Manila’s river and drainage system. We have also seen what a massive earthquake could do to an unprepared city like Haiti.

“While there is nothing that we could do to control the destructive power of these natural phenomena, there are steps that we could take to limit the amount of damage.”

If the rapid growth in urban populations is to be safe and sustainable, then new dwellings will need to be built that meet high standards of durability.

The UN Challenge of Slums report from 2003 (www.unhabitat.org/pmss/listItemDetails.aspx?publicationID=1156) broke with past orthodoxy that slums must be cleared, arguing that slums should be seen as positive economic forces, incubators for budding entrepreneurs that offer a gateway to better things for new migrants.

Muhammad Khadim of UN-Habitat summed up the new thinking:

“Ten years ago, we used to dream that cities would become slum-free,” he said. But “the approach has changed. People see the positives. The approach now is not to clear them but to improve them gradually (and) regularise land tenure.”

The arguments behind embracing slums come from the economic changes across developing countries since the 1970s. Growing informal economies combined with fewer social provisions and the shift to urban from rural communities have all contributed to the explosion in slums and informal housing.

Manila is a city of stark and startling contrasts: there are glitzy shopping malls and high-rise office buildings, but also large slums and hungry people begging and selling trinkets on the city’s roads.

It’s a place where the slum clearance-vs-renovation debate is hot and current. The Philippines is currently in the midst of a campaign to clear slums in Manila and move people back to the countryside.

“Many of our people are no longer interested in agriculture, so we need to give them incentives to go back,” Cecilia Alba, head of the national Housing and Urban Development Co-ordinating Council, told the New Statesman magazine. “If we had to rehouse the slum-dwellers inside Manila in medium-rise housing, it would cost a third of the national budget.”

Palafox has a different vision – rebuilding a slum community from top to bottom.

An architect, environmental planner, urban planner and development consultant, Palafox runs one of the top architecture firms in the Philippines, employing more than 100 staff and consultants.

Usually occupied with office buildings in the go-go new business centres of the Middle East and Asia, Palafox has turned his attention to Estero de San Miguel, a Manila slum that is home to some 1,200 families, or 6,000 people.

Families are packed into tiny rooms in a labyrinthine slum complex beside a canal. The rooms are made of wood and floored with linoleum and have to be accessed through a narrow tunnel and tight connecting corridors.

Palafox’s plan is to work with the residents and rebuild it in its current location. In place of makeshift shacks will come modular homes, 10 square metres in size with space for shops and bicycle parking.

The design has the homes extend above a walkway, imitating the way the original slum structures were built.

Palafox is applying innovative thinking to the problem: taking his design direction from the dwellings slum residents build:  “The slum-dwellers,” he explained to the New Statesman, “are experts at live-work space design. They spontaneously do mixed-use! We just have to learn from them.”

Re-housing the residents on site means they can continue to play their role in the city’s economy, and do not have to make a long commute to jobs and opportunities.

Palafox also rebuts complaints about the cost of his plan, arguing the scale of corruption in the Philippines costs just as much.

“OK, the total cost of rehousing slum-dwellers in situ is 30 per cent of GDP (but) I calculate we lose about 30 per cent of the country’s wealth through corruption. If we didn’t have corruption, we wouldn’t need to tolerate slums.”

Another passionate advocate of working with slum dwellers is Father Norberto Carcellar from the Homeless People’s Federation (http://sdinet.org/countries/philippines.htm).

“We have to recognize the value of slum-dwellers to the city,” he said. “These are the ones who drive your car, clean your house and run your store. If these people were cleared from the city, the city would die. Slum-dwellers add social, political and economic value to the city.”

Even in its current form, Estero de San Miguel is a vibrant place, with an Internet café and a volunteer police force.

A BBC report found it lively and economically viable because it has educational and communication technologies that improve living conditions. The residents make their living working as cheap labour for the city.

Oliver Baldera, a carpenter, lives with his wife and four children:

“We’ve been here more than 10 years,” he told the New Statesman. “There’s no choice.

“It’s easier to get a job here and I can earn 400 pesos a day. I can send the kids to school and they eat three times a day – but it’s not enough. I need more space.”

Brazilian Design For New Urban, Middle-Class World

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Countries across the global South are experiencing rapid urbanization as people move to cities for better economic opportunities — and this massive social change is creating new business opportunities. Those who recognize how fundamentally people’s lifestyles are changing will be those who will benefit from this big shift in populations.

Finding ways to live well in urban areas will be critical to determining whether this move repeats past urban failures — from the favelas of Brazil to the slums of India — or introduces a new way of living that is exciting and colorful. Design and designers will be critical to this change.

One young design company in Brazil, Sao Paulo-based furniture studio NUUN  (nuun.nu), is attempting to resolve a dilemma common across the rapidly urbanizing global South: How to create a design aesthetic that fits with the new way of living and being?

The company consists of designer and founder João Eulálio Kaarah and architects Renato Périgo and Carolina Sverner.

Périgo specializes in furniture and interior design, while Carolina Sverner worked with respected Japanese architect, Shigeru Ban (shigerubanarchitects.com), who is well known for designing buildings and houses made from paper and for creating easy-to-build homes for people after a disaster has struck (http://www.ted.com/talks/shigeru_ban_emergency_shelters_made_from_paper).

A collaboration among upcoming artists, designers and architects, NUUN tries to infuse its designs with a sense of “brazilianness”. Brazilianness is a modern aesthetic, made for modern lifestyles in the new urban landscape, that draws on aspects of Brazil’s culture and environment.

The young studio’s first collection of furniture offers simplicity. Called Eos, it tries to blend urban cosmopolitanism with raw nature. Brazil is known for its jam-packed urban cities as well as its vast expanse of Amazon rainforest. In practice, NUUN’s look is a mix of contrasts redolent of what used to be called brutalism: concrete mixed with glass, steel, wood and semi-precious gems. NUUN takes inspiration from NASA’s Earth Observation System (EOS): the collection vibes off of space satellites, antennae and the dry soil of the backwoods. NUUN says that “despite its Martian features, [the collection] is as Brazilian as it comes”. There is the modular Panorama sofa (http://nuun.nu/products/panorama) in five colors, capable of being re-shaped to fit a variety of living arrangements. A glass-topped coffee table with a concrete base and a side table with a carbon steel metallic structure to complement the sofa.

Elsewhere in the world of Brazilian design, footwear brand Grendene S.A. (http://ri.grendene.com.br/EN/Company/Profile) has become one of the world’s largest producers of footwear and made one of its founders a billionaire. And Grendene has boosted its international success by turning to another Brazilian success: supermodel Gisele Bündchen (giselebündchen.com.br).

Grendene began in 1971 and owns various successful shoe brands, including Melissa (melissa.com.br/en/), Grendha, Ilhabela, Zaxy, Cartago, Ipanema, Pega Forte, Grendene Kids and Grendene Baby.

It has six industrial zones with 13 footwear factories and can produce 240 million pairs of shoes a year. It undertakes all areas of production— from making its own moulds for the shoes to creating PVC (polyvinyl chloride) (http://en.wikipedia.org/wiki/Polyvinyl_chloride) – and handles its own distribution.

While Grendene is already a well-known shoe brand in Brazil, it wanted to expand its presence overseas to increase profits. Named after the two brothers who founded the company, Alexandre Grendene Bartelle and Pedro Grendene Bartelle, Grendene started working with supermodel Gisele Bündchen in 2002 to help her launch her own line of affordable flip-flops, iPanema (ipanemaflipflops.co.uk). The brightly colored sandals with elaborate patterns became an instant success.

But do celebrity endorsements really work? In the case of Bündchen and Grendene, the answer is yes. According to Forbes, 25 million pairs of the flip-flops and sandals are sold every year, accounting for 60 per cent of Grendene’s annual exports of about US $250 million.

Brazil was able to produce 864 million pairs of shoes in 2012, up 5.5 per cent from 2011.

Of these, 113 million pairs were exported to the United States, Argentina and France.

Brazil, like many other countries, has had to work out how it could compete with cheaper shoe imports from China. The strategy it chose was to target the growing number of middle-class people both in Brazil and elsewhere, as well as the high end of the market.

In 1979, Grendene created the Melissa brand, which has now become a coveted style leader. It collaborates with top design names such as Karl Lagerfeld and architect Zaha Hadid.

Making a partnership with Bündchen is part of the company’s strategy to reach higher-income buyers.

And it is working: Grendene increased its export revenue by 50 per cent in 2013.

Co-founder Alexandre Grendene Bartelle became a billionaire according to Forbes World’s Billionaires list and is worth US $1.4 billion. He owns 41 per cent of Grendene S.A. and close to 40 per cent of the Dell Anno brand.

This is a critical lesson for manufacturers in the global South. Grendene had achieved strong market dominance at home, and was already benefiting from growing wealth among Brazil’s middle classes. But it was the overseas market that had the potential to clinch even more profits for the company.

Bündchen’s high brand profile has enabled the company to compete head-to-head with the well-known Brazilian flip-flop brand, Havaianas (havaianas-store.com).

Another modern design leader owned by Grendene, Dell Anno (lojasdellanno.com.br), is a maker of modernist cabinets and furniture.

Dell Anno only use wood from renewable forest sources, to protect and preserve the Amazon and other native forests. Dell Anno tries to recycle as much as possible: up to 80 per cent of the water used in manufacturing is recycled, and byproducts from the production process such as a sawdust, wood, plastic and cardboard are also reused.

Dell Anno makes a full range of furniture for kitchens, bedrooms, closets, home theatres, home offices, service areas, restrooms and commercial environments. Dell Anno uses research and development to study trends and advise customers on the best options. The brand offers its staff training to help standardize customer service, and also has an excellent blog covering developments in modern design around the world (http://www.lojasdellanno.com.br/blog/).
