Hi everyone. First time poster here and a question regarding the shed Im going to build. I attached a picture of what the floor framing currently looks like. Haven't build the shed just yet so I have the opportunity to modify. This is to be an 8x10 shed made of barn board and 2x4's for the structure. Anyways...the original plan was to run 4x4's over 2 lengths of concrete piers and account for about 1' cantilever. Then structure the floor with 2x6s running perpendicular (similar to how one would build a deck. Only issue with that (and stupid me for not really thinking it through until the footings were poured), but that would put the shed floor over 12" above grade. So what was suggested to me was to just frame the shed directly on the saddles as the picture shows. I'm not so worried about the 8' lengths as that is somewhat still compliant with proper beam/joist theory, but the walls are going to be build on the 10' lengths with that 10' 2x6 basically floating, minus a couple blocks tying it into the beam ( the beam is composed of 2 2x6s sitting in a 4x4 bracket with 1/2" OBS to fill the gap). All wood for the floor structure is PT btw. I've asked a couple people and they didn't really think twice about saying it'll surely still be fine but I just thought I'd ask around here for some extra reassurance or anything I can do to beef it up a bit more before I build on top. Maybe a few more blocks on the 10' edges is the best I can do? Thanks!

Hopefully this is the right section for this question. I want to build a small stair landing on the side of my 24' x 36' cottage. The landing will be 6' x 4'. It will be bonded to the cottage at the rim joists and sono tubes for the outer corners. My cottage sits on 3 beams that sit on concrete pillars. The ledger board for the new stairs will be bonded to the rim joists. Those joists are 12 feet long and there are two of them going along the 24 foot side of the cottage. I want to sister those joists up and was thinking about a 12' board in the center of the joists so as to sister the two 12' joists into one 24' joists. The inside ends of the joists are sitting on a center beam. My question is whether turning two 12' joists into one 24' joist, by sistering them, would have any detrimental effect on the structure.
