A School that Bridges Between Tolou Castles

The Tolou clan homes in the Fujian Province are large, circular rammed earth mini-castles constructed from the 11th to 20th centuries. Architect Li Xiaodong has completed a school in Fujian, China, which forms a bridge over a creek between two castles.

While the bridge is not constructed of earth, it represents work that literally bridges between the languages of non-industrial and industrial societies and the relationships between earth buildings and industrial materials.

The bridge/school is constructed of steel, wood and concrete and the material palette compliments the stone and rammed earth clan houses. The transparency of the bridge’s cladding is also in contrast to the impenetrable fortress clan houses.

A ‘Model City’

drdharchitects’ proposal for the Shenzhen and Hong Kong Bi-City Biennale of Urbanism Architecture seeks to address the individual and collective lives of the inhabitants, and future inhabitants, of the World’s big cities. This seems of particular relevance given the extraordinary and rapid growth of Chinese cities like Shenzhen, as the country goes through a dramatic process of urbanisation. With the help of local school children from Shenzhen they proposed the creation of a miniature city, made of clay.

They wanted to engage local school children in imagining their own city. The process started by asking them to think about their home, through building a collection of miniature clay houses. drdharchitects asked them a series of questions such as where an entrance or window might be; how these played a part in defining the overall appearance of their buildings and how it might speak to its neighbours. It concluded by asking them to consider the individual house as part of the collective city, how it might be laid out, its patterns and the relationships between things.

Ma Terre Première Pour Construire Demain

Ma Terre Première Pour Construire Demain is an exhibition on earth raw as a building material as it pertains to environmental, economic and aesthetic of today and tomorrow. The first exhibition of this magnitude on the subject, Ma Terre Première Pour Construire Demain reveals the full potential of this granular material found in geology, physics, architecture and art. The exhibition was produced in collaboration with the research laboratory of the Ecole Nationale Supérieure d’Architecture de Grenoble, CRATerre. Ma Terre Première Pour Construire Demain is co-produced with four regional agencies as the host in turn until 2013: The Flying Strasbourg, the Science Forum Villeneuve d’Ascq, the Pont du Gard and Confluence Museum in Lyon.

Bâtir en Terre

The French language book, Bâtir en Terre, by Romain Anger and Laetitia Fontaine was published as part of the exhibition Ma Terre Première Pour Construire Demain (Earth Today for Construction Tomorrow). The book presents the unique heritage of earth construction, from the mythical Shibam in Yemen The “Manhattan of the desert to the strange group of Hakka houses in China. The book includes projects from Europe and documents the achievements of contemporary architects, fascinated by the qualities of the material. The book offers simple and fun experiments to understand physio-chemical properties of earth from which could arise ways to develop alternatives to industrial materials like cement.

Subnature: Architecture’s Other Environments

Books on architectural history and theory often overlook mud and dust as a material of architecture and cities. As author David Gissen points out in his new book, “Subnature: Architecture’s Other Environments“, the eradication of mud from urban environments is often seen as a form of cultural advancement. “Massive paving projects were undertaken to remove muddy pockets from the centers of cities, and drainage efforts eliminated mud from most public parklands. The appearance of mud [in the ninetieth and twentieth centuries] became emblematic of urban engineering failures and impending pathologies”, writes Gissen. He then goes on to describe the expanded potential for this material from a historical and theoretical perspective in projects such as de Paor architects pavillion for the Venice Bienale, which was constructed of 21 tons of Irish peat and Otero-Pailos’s The Ethics of Dust, and experimental preservation project which captures an interiors dust in latex that is then assembled as an interior facade. The book is not about fashionable topics surrounding sustainability and ecology. With chapters on smoke, dankness, debris, exhaust, weeds and other counter-architectural conditions, Gissen seeks to expand one’s perception of truly alternative materials in a positively original way.

Book Description
We are conditioned over time to regard environmental forces such as dust, mud, gas, smoke, debris, weeds, and insects as inimical to architecture. Much of today’s discussion about sustainable and green design revolves around efforts to clean or filter out these primitive elements. While mostly the direct result of human habitation, these ‘subnatural forces’ are nothing new. In fact, our ability to manage these forces has long defined the limits of civilized life. From its origins, architecture has been engaged in both fighting and embracing these so-called destructive forces. In Subnature, David Gissen, author of our critically acclaimed Big and Green, examines experimental work by today’s leading designers, scholars, philosophers, and biologists that rejects the idea that humans can somehow recreate a purely natural world, free of the untidy elements that actually constitute nature. Each chapter provides an examination of a particular form of subnature and its actualization in contemporary design practice.

The exhilarating and at times unsettling work featured in Subnature suggests an alternative view of natural processes and ecosystems and their relationships to human society and architecture. R&Sien’s Mosquito Bottleneck house in Trinidad uses a skin that actually attracts mosquitoes and moves them through the building, while keeping them separate from the occupants. In his building designs the architect Philippe Rahm draws the dank air from the earth and the gasses and moisture from our breath to define new forms of spatial experience. In his Underground House, Mollier House, and Omnisport Hall, Rahm forces us to consider the odor of soil and the emissions from our body as the natural context of a future architecture. [Cero 9]’s design for the Magic Mountain captures excess heat emitted from a power generator in Ames, Iowa, to fuel a rose garden that embellishes the industrial site and creates a natural mountain rising above the city’s skyline. Subnature looks beyond LEED ratings, green roofs, and solar panels toward a progressive architecture based on a radical new conception of nature.

Dune Anti-Desertification Architecture

Dune Anti-Desertification Architecture investigates adaptive (as opposed to mitigatory) strategies leading to the creation of a climate-conscious
architecture that responds to the extreme environments of tomorrow’s globally-warmed world. Highly speculative yet buildable, the scheme aims to find innovative solutions to combat desertification in the Sahel region of Africa, where sand dunes are currently moving southward at a breathtaking
pace of around 600m per year, ruining the land and making it impossible for the inhabitants of this area to make a living or even stay in their homes. The forced migration of desertification refugees is perhaps more threatening in Nigeria than anywhere else. With a population of over 140 million people, Nigeria is the most populous country in Africa, with serious desertification issues throughout its northern states. It was Nigeria’s former president, Olusegun Obasanjo, who initiated the anti-desertification Green Wall Sahara initiative in 2005. This pan-African scheme seeks to plant a shelterbelt across the continent, from Mauritania in the west to Djibouti in the east, in an attempt to stop the dunes from migrating. The trees are being planted right now.

An architectural response to this campaign would be to go beyond the mere planting of a mitigatory shelterbelt. Habitable spaces can be created in close proximity to the trees. By cutting through the sand dunes and digging down to find water and shade, an artificial oasis can be formed underground.

The sand is solidified using bacillus pasteurii, a microorganism with which professor Jason DeJong has turned sand into sandstone in a mere 1,400 minutes. This technology of organically cementing networks of sand dunes into habitable barriers that stop the desert from spreading has never been proposed before, but on hearing about this project, the professor was enthusiastic: “I do think the application you are talking about is possible”. I’m proposing anti-desertifi cation structures made out of the desert itself, sand-stopping devices made of sand: a poetic proposal that simultaneously works in a sustainable way with local materials and assets.

Special emphasis has been put on finding a solution that is high-tech in result but low-tech in application and construction, with the economical scenario being hard to pin down as this method is virgin territory. It is recognized that poor people are highly vulnerable to the effects of weather, as drought can cause famine while good rains can cause drops in crop prices. The architecture presented here could form a stable base from which to fight back against both effects.
