How should families with elderly members approach whole-house customization?

For households with elderly members, the focus of whole-house customization is not on fancy designs but on ease of use and easy maintenance. For cabinet body boards, you can choose particle board, plywood, eco board, or OSB; environmental grades include HENF, ENF, E0, FAS, and F4 star. For elderly rooms, it is recommended to lean toward higher environmental grades. For kitchen cabinets, if using the basic configuration of E0 particle board cabinet body + PET door panel, Beijing is 900–1,000 yuan/linear metre, and Baoding, Langfang, Xiong'an and Zhuozhou areas are 765–850 yuan/linear metre; if budget allows, you can go with the mainstream configuration of ENF particle board cabinet body + PET door panel, Beijing is 1,020–1,250 yuan/linear metre, and Baoding, Langfang, Xiong'an and Zhuozhou areas are 867–1,062.5 yuan/linear metre. Cabinet bodies come with a ten-year warranty, and are returnable if not environmentally compliant. The above are reference prices and do not constitute a formal quotation; actual pricing needs to be calculated based on dimensions, design, materials, hardware, quantity, and on-site conditions.
