base for a granite hearth......

As you can see i've taken out the old fireplace and i am planning laying a granite hearth down.

My only problem is that the base the old hearth sat on is not as big as the hearth i plan to fit. It extends about 6-8 inches over each side of the current base onto the floorboards.

Obviously i'm going to sit the new hearth on a bed of sand and cement, but can this go over onto the floor boards? Or do i need to saw out some of the boards and enlarge the concrete base?

No there is no need to alter the floor. It might be an idea to lay a waterproof membrane over the whole area though to stop your bed drying out more in one area than another.
