BANGLA BARI is in pursuit of beautiful and sustainable architecture in rural Bangladesh.
Bangla Bari is a non profit, open platform, research based organization. Our portfolio includes clinics, schools, individual houses and even offices made with earth. A large portion of our work consists of researching and experimenting on materials and construction techniques. We pursue earth architecture in sophisticated form and promote the use of sustainable building materials like Compressed Earth Block (CEB), Jute based roofing (Bangla Tin) and cured bamboo. These methods not only reduces carbon footprint significantly, but also makes the building stronger. Bangla Bari is also a platform for connecting young architects who is eager to design and clients who can barely afford an architect. If you want a beautiful earth or bamboo architecture, contact us.
This is how we make an earth block:
BANGLA BARI organizes workshop and training for rural masons, students and architects. We periodically publish papers in scientific journals. We also assist to make houses for people who can not afford an architect or an engineer. The idea is simple. To be socially responsible, to actively use sustainable materials and make beautiful architecture along the way. A detail account of our mission can be found in the following scientific paper, published in PLEA 2014.(Exploring New Methods of Constructing Houses with Sustainable Materials in Rural Bangladesh)

Why Design differently?
There are over hundred million people inhibiting rural areas of Bangladesh. Most of the country is low lying flat land with numerous rivers crisscrossing the plane. Historically, people of Bengal delta have built houses with natural and sustainable materials like mud, thatch and bamboo. The process has changed significantly over the last half a century and now the major materials used to build houses are CI sheet, Kiln baked brick, cement and wood. At present over 8000 brick factories produce nearly eight million tons of carbon emission every year. Corrugated iron industry adds another six million tons of CO2 in the air. Generally the house owners, local masons and small contractors play significant role in the construction process in the rural areas. For most of them material choices are scarce and expensive. A corrugated iron sheet house has little or no insulation and contributes to poor housing situation. The new method of construction aims to handle these challenges.
What is ahead?
This particular type of material and construction techniques has a huge potential in rural Bangladesh. Furthermore, carbon emission is significantly reduced in the new method, resulting in a very positive environmental impact. Since the labor cost is cheap in Bangladesh, Compressed Earth Blocks (CEB) can be produced in large scale and in much more cost effective ways. As a result, the price of house will be significantly lower and more for the rural people. The CEB machine requires investment at the beginning. However, this also has potential to create local entrepreneurs. Moreover once the new methods enter mainstream construction, more masons and entrepreneurs will be interested to build with these bricks. Jute Composite Tin on the other hand will have rather big challenge to penetrate the market because of its high price. However, since it is rust proof and once the economies of scale will be achieved in mass production, it will have a significant advantage in the coastal areas where corrosion of regular CI sheet is a major problem.
