Ten years ago in Burkina Faso, a landlocked African county, a small change started in the way people built their homes. Today that provides employment to many and is a growing way of life. It involves the construction of a simple vaulted earth roof, which was the traditional way of building for centuries, till it was replaced by other, less viable materials like tin roofs. 

The Earth Roofs for the Sahel, is a programme that is part of the Association la Voute Nubienne, (AVN) an NGO registered in France and Burkina Faso, in 2000. It promotes the construction of timberless valuted earth brick houses, using a well known technique known as la Voute Nubienne (VN). The VN technique is actually an adaptation of an age old technique of building houses from the Nubian region of Egypt. The country has two seasons, a rainy one for around 4 months, and the rest of the year is the hot season with winds from the Sahara. Traditional building used earth walls, thatched roofs and some timber, but with population growth the use of timber for construction is illegal or too expensive. People often resort to sheet metal or timber beams. These materials drain family resources, sheet metal gets corroded, and they are often imported from outside at high expense. Sheet metal also has poor heat and sound insulation. 

The first prototype of a VN construction in Boromo, Burkina Faso, was built as a challenge by Thomas Granier and Séri Youlou in 1998. Next year, a VN house was built, and the Association la Voute Nubienne was founded in 2000 to promote the VN technique as a solution for affordable, sustainable housing in the Sahel.

The vault roof is built without a timber support. The roof is waterproofed using locally produced plastic sheeting over a smooth coating of mud. This way of building is not only ecologically and economically sound, but also socially viable, and all these three parameters are essential in a country that occupies the sixth to last place on the Human Development Index. Local masons are trained, and they in turn employ apprentices once they become master masons. After some experience, master masons become independent entrepreneurs. The AVN helps them through the process, and helps the entrepreneurs develop a client pool through communication and networking. Till today approximately 235 houses and 20 public buildings (including schools, dispensaries, churches and mosques) have been built. Over 115 masons have been trained and there are currently 170 apprentices.

Houses using the VN technique are more comfortable, healthy and durable. They are also safer, less prone to collapse and better in extremes of climate. They can be easily built with local materials and labour, most houses are built by bartering crops and/or labour. The families cover the housing and material cost, with AVN only covering a margin of labour and training costs. Now AVN has to cover less and less, which is a healthy sign of an active, self-sustaining system. The project is generating income and employment for many, and there have been over 7000 beneficiaries till date. The number of apprentices is increasing, which means more masons to carry out further training in the future. The vaulted roof can be converted to a flat terrace roof and the technique allows for later extension of a building, even adding a second storey onto an existing single storey building.

The simplicity of this technique, (you can read more about it here) and its involvement of the local community are key to its success. It does not require fancy equipment, skill, or technical know-how. While giving people a better way to live, it also provides a means of livelihood, essential in such places. It has led to a major reduction in the use of imported materials, as it uses local materials, earth and water, and deforestation has also reduced. The poorest of families in remote rural areas are also building with this technique. Money saved by building this way is used for health or education. 

This technique thrives because it stays as close to the people it was meant for, as possible. It is an innovation not only in design, but also in system. It traditionally comes from their own culture, it draws on local materials and skill, and creates independent entrepreneurs, reducing dependence on the mother NGO, and outside resources.

Architecture for Humanity is an initiative started in 1999, and today is a network of more than 40,000 professionals who give their time and knowledge to help those who would otherwise would not be able to afford their services. One of the ironies of our time is the fact that often, the people who are most in need of design and development services, are the ones who can least afford it. In the last ten years Architecture for Humanity has helped rebuild local communities after natural disasters, alleviate poverty and provide access to to clean water. They also work for communities struggling with urbanization, build for the differently abled, rebuild communities post-conflict, and reduce the footprint of buildings. 

One of the key areas they work in is sustainable design. They believe (very sensibly) that "Buildings not only have a physical footprint - they have an ethical footprint." Projects they work on range form community centers for tsunami affected people in Sri Lanka, to preservation of defaced structures in New Orleans after Hurricane Katrina. The projects on their site and both numerous and varied, and there is a detailed documentation of each one. Their sensitivity to culture, people and the environment, results in buildings and spaces that blend with and support the local resources, as well as revitalize the local culture and sense of community. As they say, "Design is important to every aspect of our lives. It informs the places in which we live, work, learn, heal and gather. We engage all stakeholders in the design process. We believe our clients are designers in their own right."

Cameron Sinclair is the CEO, (Chief Eternal Optimist as they call it) of Architecture for Humanity, of which he is the co-founder with Kate Stohr. He was trained as an architect in University College, London, where he developed an interest in social, cultural and humanitarian design. Ten years back he and his wife Kate had an idea while watching news of the refugees in Kosovo. Cameron said, "I bet there is more than just us who cares about these communities, who want to help and make a difference." They launched a design competition for Kosovo, and were flooded with a new ideas for refugee housing. And so Architecture for Humanity was born. You can read more on him here. They have co-authored a book 'Design Like You Give A Dam'. (I couldn't have said it better myself!)

Cameron believes that when your clients are living on less than 50 cents a day, being 'green' is not a choice. Sustainability is also about affordability, and innovation with the minimum resources.
You can request design services or offer design services. Also have a look at Open Architecture Network, another initiative by them, an online, opens-source community to share knowledge and improve living conditions. These people realize that architecture is so much more than just 'buildings'. It is the spaces we live in, and in a way our homes, workplaces and gathering places are extensions of ourselves. They shape us as much as we shape them. I quote their site "One billion people live in abject poverty. Four billion live in fragile but growing economies. One in seven people live in slum settlements. By 2020 it will be one in three. We don't need to choose between architecture or revolution. What we need is an architectural revolution."
One of the several current projects is happening in Haiti, post-earthquake. Cameron's entire posts on the home page are worth reading. A quote here, "For those not used to working in disasters the first week is chaotic, filled with stories of heroism and despair. The first responders are not the NGO's or medical personal but the families of those who are injured or lost their lives. It is an overwhelming situation to be in. It is also not the time for architects to show up thinking they can rebuild. People are trying to find their loved ones not think about what their lives will look like in 5, 10 or 15 years."

Do read their site in detail, its range and depth of work is commendable, and have a look at the video below. (lots more videos on YouTube). Its time to design like you give a dam.
