Staircase Offered-Up

The staircase has been jacked into position today, supported on accro props under the top (?) step :

Looking down from the top, the strings just protrude above floor level. These are going to be rounded off flush with the underside of the landing. There is just clearance to get a double trimmer in before the pipes, and the riser for this last step will be attached to it's front face. This will be a full, rather than half, riser, so that you can't see through into the floor/ceiling void.

The cables will need to be housed into a notch just behind the trimmers. There is enough cable slack to accommodate this.
