A house that does not fight floodwater but floats on top of it is now sheltering families in one of the most flood-prone nations on Earth. In Bangladesh, where rising rivers regularly wash away homes, a tiny dwelling called Khudi Bari stays dry by rising with the water.
A house that rises instead of drowning
Khudi Bari, which means "tiny house" in Bengali, is built on a platform supported by empty bamboo drums. When floodwater comes, the drums provide buoyancy and the entire structure lifts. When the water recedes, the house settles back onto the ground. The design is the work of architect Asif Salman and his team at the firm KB. The houses are small, roughly 3 meters by 3 meters, and cost about 60,000 Bangladeshi taka, or roughly 500 U.S. dollars, to build.
Why local families are choosing to stay
In Bangladesh's low-lying river basins, seasonal flooding is a fact of life. But extreme floods have grown more severe and unpredictable. Many families in rural areas have been forced to abandon their homes and move to cities. The Khudi Bari offers an alternative. It allows people to remain on their land, near their livelihoods, even when the water rises. The house is built with local materials and can be assembled in a few days. Families do not need to evacuate or rebuild after every flood. They simply wait for the water to go down.
The first Khudi Bari units were installed in the northern district of Kurigram, one of the areas hardest hit by annual flooding. Residents there told the architects that the house changed their lives. They no longer had to worry about losing everything to the water. The design has since drawn attention from aid organizations and government officials looking for low-cost, practical solutions to climate displacement.
A simple idea, a bamboo drum, and a platform have given people something rare in a flood zone: a home that stays a home.
