Help！ (づ￣3￣)づ╭❤～ is that grammar right？ The main argument of this text is that sustainability should be included into affordable housing. The following 3 or 4 related ideas support this argument... In many developing countries, the governments have used affordable housing as one of the goals of improving the living conditions of low-income families. Low energy affordable housing increases residents' non-housing expenditure and lead to low non-housing market demand to cause waste of public resources. Sustainable housing will have a better public environment that will strengthen the sense of belonging of the householders.
