I need some good advice from someone who knows the best way to deal with the top step and the flooring being installed in a room. Inotherwords, if I start at one side of the room and a set of steps are in the middle of the room running in the same direction as my tread, how do I connect the tread to the room flooring because it will never be in the right place to simply line up width-wise. The stair nose is the same material an also tongue and groove.
