|Size, shape, and floor plan|
To be useful and comfortable, a room must be large enough and properly shaped for its function. For example, a bedroom must be long enough for a person to lie down in and wide enough so he or she can get out of bed and in and out of the room easily. A latrine, on the other hand, only needs to be large enough for a person to sit or squat (unless people also plan to dress or wash in the same area).
The best way to make sure that a room will be large enough is to decide how large it would have to be for the largest adult likely to use or visit the home. Then the room will be comfortable for everyone.
[Note: Often the proper size and shape of a room is determined more by traditional requirements and social patterns than by physical comfort. Field workers must be sensitive to the community's needs and priorities and should explore them thoroughly with the family.]
Here are some guides for a "human" measuring unit:
- Most adults will be less than 2 meters tall;
- An adult usually needs 2/3 meter from side to nice and from front to back in order to move around; and about 1 meter, or nearly half his/her height to sit down.
