View from the side extension with part of the floor removed. The support beam in the foreground is not attached at either end - it is being supported by the subfloor. The jack in view to the left is supporting the other beam running front to back in the image. The partial beam in the center is completed rotted and has been detached from the floor most likely for several decades.
After removal of some more of the subfloor, the support beams collapsed into the cellar.
Hardwood floor removed, plus the two layers of subfloor on the left-hand side. The sub-floor visible on the right was at one point the finished floor level and was later covered over with the hardwood planking
