A Mudbrick City Wall at Hattuša

Situated in Central Anatolia, Hattuša remained the capital city of the Hittites from 1650/1600 to around 1200 BC. Here, as recently as 2003 to 2005, the German Archaeological Institute has rebuilt one stretch of the mudbrick city wall. The scope of this project in experimental archaeology has been to recreate a part of the wall using the same materials the Hittites had at hand when they built their original walls so long ago. Each step necessary for the construction was fully documented so as to enable us to assess not only the amount of building materials required but also the manpower and time the Hittites must have invested in the various tasks of construction.

This volume presents the results gleaned from this documentation. From the production of the first mudbrick to the dedication of the finished structure, each and every undertaking has been described in detail and is presented here accompanied by 573 illustrations.

El Faro: The Citizens’ Initiative Pavilion


Photo credit

The architectural project of the Citizens’ Initiative Pavilion building is the work of the architect Ricardo Higueras for the Zaragoza Expo 2008.

The pavilion building will be based on energy efficiency, recycling and sustainability. Both the building’s shape and its use are based on the traditional ceramic pitcher. The materials used are natural and come straight from the earth: straw, wood, and clay. Prefabricated clay-plastered panels were attached to a super-structure to enclose the pavillion.

Bousillage Construction


The Gaudet House c. 1830, Lutcher, Louisiana

Bousillage, or bouzillage, a hybrid mud brick/cob/wattle and daub technique is a mixture of clay and Spanish moss or clay and grass that is used as a plaster to fill the spaces between structural framing and particularly found in French Vernacular architecture of Louisiana of the early 1700s. A series of wood bars (barreaux), set between the posts, helped to hold the plaster in place. Bousillage, molded into bricks, was also used as infilling between posts; then called briquette-entre-poteaux. The bousillage formed a solid mud wall that was plastered and then painted. The bousillage also formed a very effective insulation.


French Acadienne house in Lyon, France

The tradition was brought to New Orleans from France by the Acadienne (Cajun). The technique also has Naive American influences. This paper describes how “When the French built in Louisiana, their earliest houses (maison) were of this frame structure, but with the post in the ground (poteaux en terre). Sometimes the post were placed close together palisade fashion (cabane). This was a technique used by local Indians. The Indians infilled the cracks between the posts with a mixture of mud and retted Spanish moss. The French did likewise and called this mixture “bousillage”. The first framed structures were covered with horizontal cypress boards (madriers). The roof (couverture) frame was finished with cypress bark, shakes, boards, or palmetto thatch. All of these earliest structures had dirt floors and were usually only one room deep and two rooms wide separated by a fireplace.”

Tarrawarra Museum of Art

Intended to emerge powerfully from the landscape this ultra modern gallery displays the talents of Melbourne architect Allan Powell. Almost like an earthworks sculpture that can be read as an artefact, the TarraWarra Musem of Art in Yarra Glen is a monument to modernism. Allan Powell has constructed a simple shape with the effect of a half built or buried building, which confounds the eye and engages the senses. The stunning tan and clay coloured structure rises out of the green vines of the Yarra Valley creating an unexpected vision in the valley. Sensually curved around the site, the building is primarily of dressed stone and rendered walls, coloured rendered concrete walls, and rammed earth walls, and the architect has achieved the feeling that ‘ this building is of the earth’. Visitors to this new gallery are convinced that the complex is of handcrafted natural materials and that each of the columns is different. TarraWarra Museum of Art has been entered into Institutional new category of the architecture awards. [ Download PDF ]

Tecnobarro and Quincha Metálica

Usualmente, cuando se habla de construcción con tierra cruda, se piensa inmediatamente en la construcción con “adobe”, sin embargo ambos términos no son sinónimos: el adobe es una de las tantas técnicas de construcción con tierra. Entre algunas de ellas destacan las tradicionales y más utilizadas en nuestro país, como lo son el tapial y la quincha, y otras técnicas mixtas nuevas, como el denominado tecnobarro y la quincha metálica.

Library and Archive at Douai Abbey

Architect David Richmond & Partners and structural engineer Price & Myers are creating a rammed earth wall using local soil for a new library and archive at Douai Abbey. The proposed 300mm-thick, 2.7m-tall earth walls, which will be built on a 100mm-tall concrete plinth, offer the right amount of thermal mass to ensure a stable internal temperature. When built, it will be the only library in the UK to use rammed earth technology. It is also the first time that either the architect or the structural engineer have worked with rammed earth.

The Earthen Homes of Yongding County


Photo by Barbara Koh/New York Times

From China’s Fujian coast, it’s a grinding drive up narrow roads through villages built around exhausted coal mines to reach the remote mountains of Yongding. Morning mist clings to the slopes of dense trees and brush. Below, in a valley, rests an eerie collection of beige cylindrical structures, one as enormous as a football field. This sci-fi scenery is peculiar to southern China and concentrated in Yongding County. The bizarre edifices, which the Chinese say foreign surveillance has, over the years, mistaken for missile silos and U.F.O.’s, are decades- and centuries-old and made of rammed earth. They are still homes to the Hakka, a Han Chinese nomadic group.

Koudougou Central Market, Burkina Faso

The impact of Koudougou’s Central Market, designed by the Swiss Agency for Development and Cooperation (SDC) / Laurent Séchaud / Pierre Jequier for the Koudougou Municipality and completed in 2005, is twofold: at the urban scale, it reinforces and enhances the fabric of a mid-sized town, providing a monumental civic space for commercial and social exchange. On the level of construction, it introduces simple and easily assimilated improvements to a traditional material – stabilised earth – which allow it to achieve its full aesthetic and environmental potential. By using blocks of compressed earth, the market not only demonstrates the superior climactic performance of the local building material, but also shows how humble earth blocks can be used to create a sophisticated pattern language of vaults, domes and arches.

The market is the third of its type to be built under the direction of the Swiss Agency for Development and Cooperation (SDC) in cooperation with the Programme de Développement des Villes Moyennes of the Burkina Faso government, which aims to strengthen the country’s mid-sized towns through building commercial infrastructures. The market was the result of a truly participatory process that brought together and engaged the entire community in the site selection, design and construction of the market as well as its continuing use. A 1:1 prototype of a typical retail space was constructed which helped facilitate communication between the different collaborators, simultaneously allowing refinement of the design, development of innovative construction techniques and practical training of the local masons.
