Mr. Nhan's land is an inherited piece of land belonging to three households, instead of cutting it into 3 linear tube houses, we propose a spiral structure so that the space blocks roll together, and revolve around a central garden conceived as a microclimate solution. In that mix, there exists space for four families to live together. In the end, it's more than a house, it's a space for people to live together, wake up and cook together, talk and care for children together. Besides, it still thoroughly solves the land ownership mentality and internal conflicts of a multi-generation family.
