We need to change the traditional problems in townhouse. We use different themes on different floors, so that each family member has its own space. You can also learn from each other in different spaces and accept different interests. In addition, we also use the smart home system in this design to put in every important function of the family, such as weather forecast, home management, elderly care, gas detection…. to make a family's functions more abundant. Create a house belonging to three generation families.
