Build your own house. Can you build a house according to the design just by downloading the design from the Internet? Do you still need construction drawings or something?
Strictly speaking, building a house requires a series of drawings, such as floor plans, construction drawings and renderings. And it can only be built after careful accounting, so it can also be guaranteed in terms of building safety. But at present, some people only have a floor plan to build a house, but there may be potential dangers in building safety and house details. For those who don't know about architectural knowledge, they may not understand the structure of the house, so they are easily fooled by the contractor.
