Building home for Nguyễn Văn Lành family

Mr. Nguyễn Văn Lành (64) lives with his wife (67) and the son (32) in a remote area of Vinh Loc commune of Hong Dan district, which can be accessed by motorcycle via a very rough track and 1km boat ride on major local river.
Mr. Nguyễn Văn Lành was born and raised on their current property and his wife has been living there since their marriage 40 years ago. Almost nothing left of the original childhood house of Mr. The self-made shelter in which they are currently living has worn out. Rain leaks through the ceilings and walls, which makes the clay floor wet and very slippery and unsafe.
The family has a pond on their property in which they breed shrimps, which generates a quarterly income of 5,000,000 đ (AUD$340). Their son works on casual basis subject to availability of work.
