19 floor decoration, can we start without design drawings?

There is no design drawing for the decoration. If you decorate yourself, you probably don't need it, because you can't read the design drawings.

For the property, you can say that you decorated it yourself. If you decorate yourself, you don't need to provide design drawings, just provide your own ID card.

If you find a decoration company to install, you need the decoration company to provide business license, design and construction qualification and graphic designer drawings.

For details about what qualifications the decoration company needs, please consult Zefuju Decoration.

I hope I can help you!
