First of all, it is necessary to clarify the use of the house, whether it is for self-occupation, rental or commercial use (such as homestay, office, etc.). This will affect the design style, size and layout of the house. For example, self-occupied houses may pay more attention to the living habits and personal preferences of residents and will design warm and comfortable bedrooms and fully functional kitchens; while houses for commercial use may emphasize space utilization and traffic flow lines more.
