Interesting finding. I was asked to inspect the installation of the subfloor in this home and found the following. The floor joists are 2" x 10" - 16" o.c. attached to built-up 2" x 12" beams. The home is approximately 30’ wide with the beams spaced 10" o.c. (joist span 10’). The floor joists are cantilevered approximately 5" on all exterior walls. There is a gable roof but the attic was not entered to determine the type framing.
Looks like this platform was constructed for brick veneer that was not installed. The floor joist on the gable ends do not have blocking installed and are only supported by the beams every 10’. This does not appear to be adequate to me. I would like your input on 2 issues. 1) would blocking between these joists provide adequate support? 2) would the installation of brick veneer be sufficient to bear the load of the end walls since the sill plate is not covering both the block/brick? There is adequate footing for a veneer wall.
Any input would be appreciated.
