What is the most sensible way to plan wardrobe zones?

Don't start drawing grids for wardrobe zones right away. First order things by who uses it, what gets hung, and what gets folded. The handiest layout is off-season bedding on top, a hanging section in the middle with enough length for both long and short garments, and drawers below for underwear and socks. Don't set the hanging rod much above your height; it should be comfortable to reach without strain. Too many shelves are a waste; hang whenever you can instead of folding. Prices are tiered by configuration: basic configuration E0 particle board + PET door panel, Beijing 500–550 yuan/㎡, Baoding, Langfang, Xiong'an and Zhuozhou 425–467.5 yuan/㎡; mainstream configuration ENF particle board + PET door panel, Beijing 700–800 yuan/㎡, Baoding, Langfang, Xiong'an and Zhuozhou 595–680 yuan/㎡; upgraded configuration ENF eco board + PET door panel, Beijing 950–1,100 yuan/㎡, Baoding, Langfang, Xiong'an and Zhuozhou 807.5–935 yuan/㎡. The above are reference prices and do not constitute a formal quotation; actual pricing depends on dimensions, hardware, and on-site calculation.
