I have a house and I want to separate the floor so that I can apply a different material. Now the problem is that when I go to edit mode and press "P" and "Selection" the floor disappears it creates a new cube, but there is no selectable mesh anymore.

Can someone point me in the right direction as to what could be happening? Thanks
