How do you negotiate the price for whole-house customization?

Don't start by pushing down the total price; break the configuration down and discuss it piece by piece. Custom wardrobes are priced by projected area, so you can ask exactly which tier is being used: basic configuration E0 particle board + PET door panel in Beijing is 500–550 yuan/㎡, mainstream configuration ENF particle board + PET door panel in Beijing is 700–800 yuan/㎡, upgraded configuration ENF eco board + PET door panel in Beijing is 950–1,100 yuan/㎡. Once the tier is set, it is reasonable to discuss the room for concession. Custom kitchen cabinets are priced by linear metre: basic configuration E0 particle board cabinet body + PET door panel in Beijing is 900–1,000 yuan/linear metre, mainstream configuration ENF particle board cabinet body + PET door panel in Beijing is 1,020–1,250 yuan/linear metre, upgraded configuration ENF eco board cabinet body + PET door panel in Beijing is 1,300–1,650 yuan/linear metre. Hardware options include Blum, Hettich, DTC, Higold, and Hegu; specifying the brand actually makes price comparison easier. The above are reference prices and do not constitute a formal quotation; the actual price needs further calculation based on dimensions, design, materials, hardware, quantity, and site conditions.
