Question: How is the surcharge calculated for whole-house customization extra-high cabinets exceeding 2.4 m?

Answer: For cabinets exceeding 2.4 m, the price is usually not simply the original unit price multiplied by the area; it depends on how the increased height is built: whether the whole cabinet is heightened, the upper cabinet is separated, or a top cabinet or filler panel is added. During measurement, wall flatness, kickboard, and internal/external corners are confirmed first, and then the closing method is decided; all of these affect how the surcharge is calculated. It is recommended to have the vendor itemize the cabinet body, door panel, hardware, and height-increase components according to the drawings. Our production cycle is usually 15–45 days, affected by panels, craftsmanship, and scheduling; for extra-high cabinets, it is best to communicate in advance.
