At present, we don't know the height or floor of the building.

In general, the construction price of this aluminum-plastic board is around 500 yuan /m2.

The height is not high, and the external wall construction price of ordinary materials can be as low as 280 yuan /m2.

High height, great difficulty, and clear requirements for materials, such as aluminum-plastic plate thickness and aluminum thick coating.

Then 550 yuan/square meter is not necessarily expensive.

The total cost is not less than 90,000 yuan.
