In 2002 architecture student Anna Heringer and several of her classmates at Kunstuniversität Linz conducted a comprehensive analysis of the civic and economic structure of the Bangladeshi village of Rudrapur. They identified a lack of educational opportunities for villagers, and Heringer designed the Handmade School, her master’s thesis, in response. In 2004 she approached the local nongovernmental organizations that were already operating a school in the village, and they adopted her design as a framework for expansion. After a year of planning and fundraising they broke ground on the project in 2005 under the guidance of Heringer and Berlin architect Eike Roswag, who assumed the job of construction manager.
The structure is made primarily of earth, a traditional building material in the region, to which Heringer added local clay, sand, and straw for increased durability. A number of improvements upon local building traditions were introduced, such as a brick foundation to strengthen the structure and a plastic moisture barrier between the foundation and the walls. Resident unskilled laborers were trained in the building technique and performed almost all of the construction. In the completed school, thick earthen walls enclose three ground-floor classrooms and a system of play caves for students; the second story has an earthen floor and walls of light and airy bamboo latticework. Local fabrics add bright color throughout. With its innovative approach to traditional methods and materials, Handmade School has stimulated interest in architecture and set new regional standards for building.
Anna Heringer graduated from University of Art and Industrial Design Linz in 2004, with her diploma project "School—handmade in Bangladesh." After finishing that building project in cooperation with Eike Roswag, she planned and built DESI vocational school and HOMEmade project on rural housing in Bangladesh. Since 2008 she has been a visiting professor at University of Art and Industrial Design Linz and director of BASE habitat/project studio for building in developing countries. In 2010 she received a nomination to Honorary Professor of the UNESCO Chair “Earthen Architecture.” An important focus of her work is the training of young architects through various lectures and hands-on workshops.
Eike Roswag studied architecture at Technische Universität Berlin. In 2003, together with his partners, he founded Ziegert Roswag Seiler Architekten Ingenieure, based in Berlin. As a specialist in earthen building and natural building materials, he realized several projects in both national and international contexts. Since his participation in projects in Mexico with Technische Universität Berlin, development cooperation has become an important part of his work.
One of Heringer’s goals was to prove that a stable and durable two-story building can be constructed with earth, the cheapest and most accessible and environmentally friendly construction material in rural Bangladesh. The school’s concrete foundation supports massive groundfloor walls of earth, which in turn support the very light bamboo walls of the second floor. The building’s two stories each have a distinct character, and the school overall merges with its surroundings.
The school’s ground-floor walls are made of a mixture of earth, sand, and straw. Necessarily thick, they regulate the interior climate, acting as a buffer against temperature and humidity changes. The plasticity of the material inspired Heringer to create cave-like play retreats for the students in the back wall of the building.
These short videos document the process of building the Handmade School, showing, for example, water buffalo slowly mixing clay. Heringer and Martin Rauch, her professor and a leading practitioner of earth architecture, filmed Ziegelwerke (Brick factories), one of the videos, as they drove past a series of neighboring industrial brick plants. Bangladesh’s growing population—it is already among the most densely populated countries in the world—is threatening its biggest industry, agriculture, as arable land is covered by housing and industry. The innumerable small brick factories in this clip underscore Heringer’s interest in sustainable earth architecture.
Since completing METI – Handmade School in 2006, Heringer and her team have built a vocational school for electricians (2) and three two-story family houses (3) in Rudrapur, using mostly the same construction techniques. Traditionally, buildings in Rudrapur are one story high, but those Heringer has designed all have two stories. This use of vertical space minimizes the buildings’ footprints, leaving more land free for agricultural use.
