Which parts of whole-house customization should not be skimped on?

In whole-house customization, the parts you should least skimp on are the environmental grade of cabinet body boards and the hardware. Boards are in close daily contact, so the environmental grade should be at least E0, and ENF if budget allows; for hardware, choose brands such as Blum, Hettich, and DTC—if hinges and slides are a bit inferior, sagging door panels and sticking drawers after a few years are the most frustrating. Do not skimp on edge banding either; PUR edge banding or laser edge banding is more moisture-resistant. For the basic kitchen cabinet configuration of E0 particle board cabinet body + PET door panel, Beijing is 900–1,000 yuan/linear metre, Baoding, Langfang, Xiong'an and Zhuozhou is 765–850 yuan/linear metre; for the mainstream configuration of ENF particle board cabinet body + PET door panel, Beijing is 1,020–1,250 yuan/linear metre, Baoding, Langfang, Xiong'an and Zhuozhou is 867–1,062.5 yuan/linear metre. The above are reference prices and do not constitute a formal quotation; the actual price needs to be calculated based on dimensions, design, materials, hardware, quantity, and site conditions.
