Which whole-house customization designs seem useful but are actually impractical?

Some designs look premium but are impractical in real use. For example, cabinet shelves spaced too closely look like they help with sorting, but large items won't fit; another example is blindly pursuing door panels with complex shapes, which have high cleaning and maintenance costs. We were founded in 2013 and have delivered 2000+ projects cumulatively (F02), and we have seen many such reworks. For mainstream TV cabinet configurations, the overall reference range is 400–800 yuan/㎡ in Beijing and 340–680 yuan/㎡ in Baoding, Langfang, Xiong'an and Zhuozhou; for shoe cabinets, the mainstream configuration is 400–700 yuan/㎡ in Beijing and 340–595 yuan/㎡ in Baoding, Langfang, Xiong'an and Zhuozhou. The following are reference prices and do not constitute a formal quotation; actual projects must be further calculated based on dimensions, design, materials, hardware, quantity, and site conditions.
