I want to customize a shoe cabinet, 1.8 m high and 2.4 m wide. About how much would it cost?

Based on the dimensions you provided (1.8 m high × 2.4 m wide), the projected area is approximately 4.32 m². In the Beijing area, the reference price for a shoe cabinet is 400–700 yuan/m², so the estimated reference budget is approximately 1,728–3,024 yuan. This is only a budget reference, not a formal quotation; the final price will be calculated based on dimensions, design, materials, hardware, quantity, region, and on-site conditions. If convenient, you can provide your city/neighborhood, cabinet body material, door panel style, and hardware configuration, and I can help you further refine the budget range.
