Handmade School | Anna Heringer + Eike Roswag

Handmade School designed by Anna Heringer & Eike Roswag, Context: Bangladesh is a fertile alluvial land in the Gulf of Bengal and the land with the highest population density in the world. On average nearly 1000 people live in every square kilometer and over 80% of the population live in rural areas. Much of the vernacular built tradition uses earth and bamboo as a building material, however, construction techniques are error-prone and many buildings lack foundations and damp proof coursing. Such buildings require regular maintenance, are often prone to damage and last on average only 10 years.
The project aims: It is particularly important to improve the quality of living in rural areas in order to counteract the continuing population migration to the cities. The primary potential for developing the building in rural areas is the low cost of labor and locally available resources such as earth and bamboo.

The project’s main strategy is to communicate and develop knowledge and skills within the local population so that they can make the best possible use of their available resources. Historic building techniques are developed and improved and the skills passed on to local tradesmen transforming in the process the image of the building techniques.
Concept and Design: METI aims to promote individual abilities and interests taking into account the different learning speeds of the schoolchildren and trainees in a free and open form of learning.
It offers an alternative to the typical frontal approach to lessons. The architecture of the new school reflects this principle and provides different kinds of spaces and uses to support this approach to teaching and learning. On the ground floor with its thick earth walls, three classrooms are located each with their own access opening to an organically shaped system of ‘caves’ to the rear of the classroom. The soft interiors of these spaces are for touching, for nestling up against, for retreating into for exploration or concentration, on one’s own or in a group.

The upper floor is by contrast light and open, the openings in its bamboo walls offering sweeping views across the surroundings, its large interior providing space for movement. The view expands across the treetops and the village pond. Light and shadows from the bamboo strips play across the earth floor and contrast with the colorful materials of the saris on the ceiling.
Building construction and techniques: The building rests on a 50cm deep brick masonry foundation rendered with a facing cement plaster. Bricks are the most common product of Bangladesh’s building manufacturing industry. Bangladesh has almost no natural reserves of stone and as an alternative, the clayey alluvial sand is fired in open circular kilns into bricks. These are used for building or are broken down for use as an aggregate for concrete or as ballast chippings. Imported coal is used to fire the kilns.

site plan

Aside from the foundation, the damp proof course was the other most fundamental addition to local earthen building skills. The damp proof course is a double layer of locally available PE-film. The ground floor is realized as load-bearing walls using a technique similar to cob walling. A straw-earth mixture with a low straw content was manufactured with the help of cows and water buffalo and then heaped on top of the foundation wall to a height of 65cm per layer. Excess material extending beyond the width of the wall is trimmed off using sharp spades after a few days. After a drying period of about a week, the next layer of cob can be applied. In the third and fourth layers, the door and window lintels and jambs were integrated as well as a ring beam made of thick bamboo canes as a wall plate for the ceiling.
The ceiling of the ground floor is a triple layer of bamboo canes with the central layer arranged perpendicular to the layers above and beneath to provide lateral stabilization and a connection between the supporting beams. A layer of planking made of split bamboo canes was laid on the central layer and filled with the earthen mixture analog to the technique often used in the ceilings of European timber-frame constructions.

The upper story is a frame construction of four-layer bamboo beams and vertical and diagonal members arranged at right angles to the building. The end of the frames at the short ends of the building and the stair also serve to stiffen the building. These are connected via additional structural members with the upper and lower sides of the main beams and equipped with additional wind bracing on the upper surface of the frame. A series of bamboo rafters at half the interval of the frame construction beneath provide support for the corrugated iron roof construction and are covered with timber paneling and adjusted in height to provide sufficient run-off.
Finishes and fittings: The exterior surface of the earth walls remains visible and the window jambs are rendered with a lime plaster. The framework construction of the green façade to the rear is made of bamboo canes seated in footings made of old good pipe and with split horizontal timbers as latticework. The interior surfaces are plastered with a clay paster and painted with a lime-based paint. The ‘caves are made of a straw-earth daub applied to a supporting structure of bamboo canes and plastered with a red earth plaster. The upper story façades are clad with window frames covered with bamboo strips and coupling elements hung onto the columns of the frame construction. The fifth layer of cob walling provides a parapet around the upper story forming a bench running around the perimeter of the building and anchoring the upper story frame construction and roof against the wind from beneath. A textile ceiling is hung beneath the roof is lit from behind in the evening. The cavity behind the textiles ventilates the roof space.

On-site labor using and training the local workforce: The masonry foundation was constructed by a company from the regional capital Dinajpur around 20km from Rudrapur. The earth building works and bamboo construction was undertaken by local laborers. The building techniques were implemented and developed on the job together with architects and tradesmen from Germany and Austria. 25 local tradesmen from the vicinity were trained during the building works creating new jobs and providing professional “help for self-help”.
Exemplary nature, transferability, follow-on projects: School handmade showcases the potential of good planning and design, from the arrangement of the building on the site to the realization of aspects in detail. Furthermore, it demonstrates the possibilities of building with earth and bamboo using simple methods as the continuation of a local rural building tradition and can serve as an example for future building developments in the area.
A stable foundation and a damp proof course are the primary technical prerequisites for building with earth, making the buildings last longer and reducing maintenance requirements. For smaller room spans, the newly developed bamboo ceiling construction can be made entirely out of local materials using handmade jute rope and bamboo dowelling.

METI, Modern Education and Training Institute: METI enables children and young people in the region to take classes up to the age of 14 and provides workshops for trade-oriented professions. The idea is to provide the rural population with access to good, holistically-oriented education. The children and young people are encouraged to develop into responsible, motivated and creative personalities and to use their skills to improve and develop their immediate rural environment. Reading, writing, and arithmetic, as well as languages, are offered in a free environment and through open forms of learning. Meditation, dance, and creative writing are part of everyday learning at the METI School as are discussions, learning as part of a group and self-critical and social behavior.
Dipshikha, Bangladesh: Dipshikha is an NGO dedicated to supporting development in the particularly poor regions of northern Bangladesh and has been active in this area for nearly 25 years. Paul Tigga, director of Dipshikha explains that the aim is to open up possibilities in the villages to make people aware of the potential at home in an attempt to strengthen the region and reduce outward migration to the cities.
