Eclipse quickly sets the climbing rope, and find a good hook for it, though it takes a few tries. The climb is fairly easy, and soon, both of them find themselves in the burned-out attic, rafter beams extending across to an open area, apparently above the next room. (You've moved into A7. With a DC 9 Stealth check, you can move to the edge of A8, as well as peer down into A4 unobserved.)
