Abstract This paper discusses about the present condition of housing in Korail bosti, it discusses about the problem in ergonomics and design in a slum and also proposes a solution to the problems. Slum dwellers in Korail Slum adopted a housing solution which is unsustainable in many ways. The idea of the whole concept is to establish a utopian idea and create a community for the slum dwellers where they can lead a better life with minimum cost and space and also create a more sustainable housing.

Korail Slum Fig[1] Bird eye view of korail slum. Korail slum in Dhaka, on the side of the Gulshan- Banani lake I one of the most largest slums in Bangladesh. It is home to about 78000 people. Among them are the people who usually conduct the odd jobs in Dhaka city. The male people mainly work as rickshaw puller, day labor, run small business, garments worker, office peon etc. The females mainly work as part time maid servant, day laborer, garments worker or sweeper. The young girls generally work in the garments. Children work in different shops or construction and transport site as child laborer. In the one-room, 80-100 sq. ft. dwellings, families with an average of four members, have created a life for themselves. Page 2
Design research on present condition of Korail Slum Housing conditions in the slum Most of the houses are made by corrugated iron (locally knows as Dhu- Tin) The houses are overcrowded; in most of the households there are more than 5 to 6 members Rent for houses range from Tk 500 to 1700 Houses closer to the water bodies had relatively lower rent Fig [2] exterior of a two storied slum Page 3
Present house conditions: Most of the houses are of 75sqft to 100 sq. ft. Houses are made up of corrugated iron sheet. Toilet facility is not well distributed. Usually all the big houses have their personal toilet space. But for those which don t have personal toilet spaces toilets are over the lake with no proper disposal of waste rather than dumping in the lake. Way to the houses built over water are of thin bamboo bridges called locally called Shaku are now improving and ensuring more safety. The drainage system is not at all efficient, although at summer and winter the slum stay dry, heavy rain causes flood in the whole area. Kitchens are also personal for each houses, it is shared by families. Fig [3] Market place Page 4
Problem with ergonomics Houses are mostly of 75 sq. ft. to 100 sq. ft. for people of at least four, with regular furniture, no adjustable furniture. Ceiling height is too low in some of the houses, about 5 6. Have all fixed furniture no adjustable furniture. Stairs were too much steeper with uneven heights of riser of 8-10 Doors were really small about only 1 10 sometimes. Toilets were really of about 6.5 sq. ft. to 7 sq. ft. Kitchens were placed mainly right beside the toilets with an area of about 9 sq. ft. to 12 sq. ft. Fig [4] inside the slum Page 5

Design proposal of BOSHOTI Concept The whole idea was to propose a new housing solution for the slum dwellers over a site of 1440 sq. ft. (60 feet x 24 feet). According to the previous analysis, it is found that slum dwellers build their houses with an area of 80-100 sq. ft. They go through all their daily activities in this small space. Boshoti proposes an idea of introducing adjustable furniture to minimize the room area and yet providing comfortable space according to the dwellers activity. Thus Boshoti introduces a utopian idea of a community with two storied modular houses for two families with four family members in each, four toilets, one bathroom, one washroom and two kitchens; where the houses transform their functions with daily activity of the dwellers throughout the day.

Ergonomic modification Rooms are of 80 sq. ft. Adjustable furniture. Whole room can be transformed according to the different activity of different time. Height of the room is 11. Stairs have a raiser of 6 and tread of 9 Doors are of 2 6. Common kitchen and toilet area. Kitchen with dimension of 6 x 7 Toilet with dimension of 4 x 4 Materials Bamboo frame Bera (bamboo sheet) for walling Bera for window shades Pieces of wooden sheet for stairs and floor Cement sheet for roof Page 8
Logical reasoning Materials - Bamboo frame is used so that the structure is strong and at the same time bamboo is cheaper and an available material in Dhaka. - Bera for walling and window shades is used as it is water resistant, light material and also really cheap and available in Bangladesh. - Wood used for flooring and stairs as it is strong. - Cement sheet is used as roofing material as it is water resistant, cheap, light and also a good insulator of sun s heat. Ergonomic modification - Rooms are of 80sq. ft. because it is difficult for the dwellers to afford a bigger space - Adjustable furniture to transform the whole room according to the different activity of different time. - Height of the room is 11 so that the hot air moves up and escape through the ventilation facility keeping the room cool. - Common kitchen and toilet area. Kitchen with dimension of 6 x 7 with two cooking stoves, storage and a small cutting space. Design - Windows on north and south to allow cross ventilation of air. - Windows on east to allow view of lake. - West wall is totally kept solid to block the sun. - Space of ventilation above 9 feet to allow hot air to escape. - Shadings of the windows are divided into two to reduce the length of shading. - Shadings of the windows are moveable. - Doors are folding to reduce its area of opening.
