House to family who lost theirs

Raising money to build a new house for a family in south of Kenya that lost their house due to heavy rains. I know the family through travels in Kenya and have known them for 5 years. It is a big family with many kids, the youngest is 7 years old. Me and some people in my surrounding are sponsoring the kids so they can go to school. The family depend heavily on the weather since they have cattle and grow their own food. There has recently been a long drought witch killed much of the animals and nothing grew for months. Now they have had a massive rain fall that flushed away their house. At the moment it is cold in south Kenya and they live in a home without walls. For a small sum it is possible to build a house that holds the weather changes and keep them warm and safe.  Thank you for your help, it is well needed and much appreciated!
