How is pricing calculated for a whole-house customization corner cabinet?

Do not simply multiply a single projected area by the unit price for a corner cabinet, because the two cabinet bodies overlap at the corner, and the calculation method easily leads to disputes. A common approach is to split it into two sections and calculate each by projected area, or to calculate by developed area; the specifics vary with the cabinet body layout and must follow the drawings. When measuring, also confirm the situation of internal and external corners, as different closing methods also affect material usage. Before signing, have the other party clearly mark on the drawings how the corner portion is measured and whether door panels and hardware are included, to avoid later add-ons.
