Stairway to heaven?

Today had some big works on the agenda: a new staircase to be built in our guest room giving entrance to the not yet developed attic yet.  Jan & my father in law went at it at an amasingly speed : new opening in ceiling, doorway opening in hallway, staircase, sliding doors in both hallway openings....all in one day. Hurray for my men!!! They rock, don't they?
