In Argentina, an innovative housing project has married good design with energy efficiency, earthquake resilience and the use of local materials and labour. As energy resources continue to be stretched around the global South, innovative building designs will be critical to the creation of sustainable housing for the future.
The happy mix of efficient modern design with affordable local materials and labour can be seen in three row houses designed and built by Buenos Aires-based Estudio BaBO (estudiobabo.com.ar) in the El Once neighbourhood in Villa La Angostura, Patagonia, southern Argentina.
The wooden houses are built in a Norwegian style. Estudio BaBO, founded in 2007, discovered that the Scandinavian nation’s housing traditions were well suited to the particular needs of the region and the local government.
The local government imposed a number of planning guidelines and restrictions that needed to be met to receive planning permission. This included creating row houses which must be made of wood – a plentiful local resource. They also had to be earthquake-safe since the region is seismically active and be able to withstand the heavy rains common to the region.
Looking around for the right guidance to tackle this brief, Estudio BaBO discovered SINTEF – Norway’s leading disseminator of research-based knowledge to the construction industry (http://www.sintef.no/home/Building-and-Infrastructure/). The Nordic nation has many wooden homes and also has similar environmental conditions and challenges to Patagonia – though its precipitation tends to fall as rain, rather than snow.
The black-painted homes look typically Norwegian, with a tasteful and clean design that does not clash with the forested surroundings. An air chamber has been created inside the homes’ walls allowing for constant ventilation of the wood, which prevents the wood from rotting and extends the life of the house. With the high rainfall of the region, wood is at risk of rotting if allowed to become damp. The air cavity also insulates the house, providing significant energy savings while keeping the interior warm and comfortable.
Adding to the energy efficiency of the design, the windows are double glazed and heat is also circulated through the floor – an efficient way to heat a home because heat rises.
To keep costs down and the project simple, the palette used for the homes is simple but attractive: black, white, wood and metal. The local wood is cypress and is painted black. The interior walls are all white and the floors are made from black granite on the ground floor and cypress wood parquet on the upper floor. The rest of the woodwork in the house is also made of cypress.
Using locally sourced materials also helps to keep costs down.
The project was initially conceived in 2009 and the houses were built in 2010-2011. While wood is plentiful in Patagonia, traditionally the use of wood in construction was rudimentary and local labour skill levels were low. This meant the design had to be simple and easy to build.
“Despite the profusion of wood as a material in the south of Argentina, the lack of specialized knowledge and of a specialized industry narrow its uses to isolated structural elements and interior and exterior finishes,” said one of the architects, Marit Haugen Stabell.
The three units of two-storey row houses each come with a living room, dining room, kitchen, toilet, two bedrooms and a laundry room. Each home also has an outdoor patio. The homes are designed to receive maximum natural light. Deploying this energy efficient design is considered unusual for Argentina and Estudio BaBO has set a new standard for sustainable housing in the country.
It looks like the CLF Houses could inspire others to look again at wood as a building material.

Development Challenges, South-South Solutions was launched as an e-newsletter in 2006 by UNDP’s South-South Cooperation Unit (now the United Nations Office for South-South Cooperation) based in New York, USA. It led on profiling the rise of the global South as an economic powerhouse and was one of the first regular publications to champion the global South’s innovators, entrepreneurs, and pioneers. It tracked the key trends that are now so profoundly reshaping how development is seen and done. This includes the rapid take-up of mobile phones and information technology in the global South (as profiled in the first issue of magazine Southern Innovator), the move to becoming a majority urban world, a growing global innovator culture, and the plethora of solutions being developed in the global South to tackle its problems and improve living conditions and boost human development. The success of the e-newsletter led to the launch of the magazine Southern Innovator.
