There are least barriers to housing deprivation in and living environment deprivation. My neighbourhood is sustainable in its own right because there are parks and playing field for children, nurseries, primary school and secondary school and a college. There are also 2 churches in the area and frequent buses through out the area. You can also find a bakery and shops in the area. My neighbourhood is ten minutes walk away form the bus station. All these in my opinion sustainable, considering third world countries.
