Hello, I'm new here with a question.......my house was made with ceiling boards and now we wanna convert the sitting room to POP; now I know the average price per sqm but the problem is I don't know how to measure the sitting room; it has 21 big(I guess that's the normal) size of ceiling boards. Please can someone tell me how many sqm a celing board is(you know those white ones)
I would be very grateul
