Under the rapid urbanization, cities in Vietnam have diverged far from their origins as low density tropical green space. Newly developed urban areas are losing their connection with nature. Binh house is one project in the “House for Trees” series, a prototypical housing design, providing green space within high density neighborhood.

Gardens located on top of the vertically stacking spaces; bounded by sliding glass doors. This strategy not only improves the microclimate by using natural ventilation and daylight in every room, but the alternately stacking openings also increase visibility and interaction between the family members.
Service areas such as the kitchen, bathrooms, stairs and corridors are located in the west to limit heat radiation exposure towards frequently occupied areas. The vertical variation of spaces creates a lopsided pressure difference. Thus, when the surrounding houses are built, natural ventilation is maintained. Thanks to these passive strategies, the house always stays cool in the tropical climate. Air conditioning system is rarely used.
The roof gardens host large trees for shading, therefore reducing indoor temperature. Vegetables can also be planted to serve its resident’s daily needs. This vertical farming solution is suitable for high-density housing whilst also contributing to Vietnamese way of life.
Using sustainable materials such as natural stone, wood, exposed concrete combined with the microclimate, this house reduces greatly operational and maintenance cost. Up to date, residents have never used furnished AC. The architecture is not only to meet the functional and aesthetic concerns, but also as a means to connect people to people and people to nature.
