etc. building a good house is both art as well as science.

❖ Ventilation: Proper flow of fresh air in and out of the house helps to get rid of
unwanted smell. For proper ventilation the house must have enough doors and
windows. Ventilation is very important as it prevents air pollutants which may affect
our health.
❖ Sunlight: Sunlight makes the house bright, warm and cheery. It disinfects the house
by killing germs and bacteria and hence protects us from diseases naturally.

of sewage waste water from the house waste not properly managed can cause
health problems.
