This depends on whether you consider a full package or a half package. The half package includes labor + auxiliary materials (basic engineering), and the full package involves the main materials.

The basic engineering fee depends on the auxiliary materials. In addition to differences depending on the brand and process acceptance standards, it also depends on the complexity of your decoration style. Generally, it will fluctuate around 400~450 yuan/square meter. The main material depends on your choice. For example, flooring, better laminate flooring costs about 120 yuan/square meter, multi-layer solid wood costs 200~350 yuan/square meter, and pure solid wood is even more expensive, so the key to decoration price is up to you. No matter how much you invest, the designer just allocates your funds reasonably.
