With the winter I have finished the exterior shell of the structure to the extent that I am able. The walls are relatively straightish and sort of vertical, but most importantly they are structurally sound. There is no more rot on the bottom edges of the studs, no more cutouts without headers. House wrap has been installed as are the windows and the vast majority of the construction debris has been cleaned out and removed.
The next stage of the project is to adjust the interior framing to be reasonably straight, parallel, level. Also I am going through very carefully to make sure that the fire damage is repaired well and appropriate fire blocking is installed. I am working from the basement up as any adjustment made to make a floor level will effect the floors above. The basement girders/beams are very close to perfectly planar (I think that one corner was about 1/32" off) and the floor joists are bearing correctly on the girders. However, since the lumber has a large amount of variance, there are joists which are 1/8" difference in height from the adjacent joist. This calls for patient endurance.

With all of that said, now is not the time to visit with small kids.
