My new house also come with broken marble (living room - dining area) approx 350sqf. Cheap ipoh marble
Then staircase up to upstairs all parquet.
I kept the marble and add-on with skirting for easy maintain in future. (e.g. you wont hurt your wall paint when polish floor & mop floor)
labour for skirting = rm200
buy skirting from marble factory = RM1.50 per pc
labour for polishing = rm350

My living hall is very classy look now. The floor also have cooling effect.

As for parquet, I change all to tiles.
labour to remove parquet + install tiles = RM5k
tiles = RM4k (niro tiles)
So...please keep the marble, then use your $ for other thing. Enjoy ya...
