Housing solution for urban, flood-prone areas in Bangladesh.

Product description Brand name and product description

The LIFT House is an amphibious housing alternative designed for low-income families living in flood-prone areas in Dhaka, Bangladesh. The two-story house combines an attached-to-the-ground service spine structure and a floating dwelling area structure. The grounded service spine features a rainwater cistern, waste storage, and vegetable garden on the first floor and toilet, kitchens, and a terrace. The dwelling area is divided into two parts, each one two-story-high for housing a family on each side.

The house was designed by Bangladeshi-Canadian architect Prithula Prosun as part of her Master’s thesis in Architecture at the University of Waterloo in 2011. The construction of the house was a collaboration of the designer, local engineers, and a local construction company. The pilot project was inaugurated in November 2010. As of 2020, the product has not been further scaled.
