Where is it most worthwhile to spend extra on whole-house customization?

For places worth spending extra on, I generally recommend prioritizing the cabinet body and worktop of the kitchen cabinet. Kitchens are humid, oily, and hot, so upgrading the cabinet body to an ENF eco board cabinet body + PET door panel is more reliable: Beijing 1,300–1,650 yuan/linear metre, Baoding, Langfang, Xiong'an and Zhuozhou 1,105–1,402.5 yuan/linear metre; for the worktop, choose quartz, with cutouts processed according to the actual dimensions of the sink and hob, and the durability is noticeably different. For the wardrobe upgrade configuration, ENF eco board + PET door panel: Beijing 950–1,100 yuan/㎡, Baoding, Langfang, Xiong'an and Zhuozhou 807.5–935 yuan/㎡, suitable for long-term use in the master bedroom. The company was founded in 2013 and has delivered 2000+ projects in total, with a ten-year warranty on cabinet bodies. The above are reference prices and do not constitute a formal quotation; actual projects need further calculation based on dimensions, design, materials, hardware, quantity, and site conditions.
