Masyado ata magastos at hassle magpa cement and tile ng lupa

I will just close off an area in our garage. Para at least patungan na lang ng new tiles. How much kaya magpa grill, tile and roof ng area na one car's length and width? Nagmukha ng tagpi tagpi bahay namin. Bakit naman kasi yung fat lab ko lahat ng makita kinakain
