Hi - I am trying to run ethernet from my attic, down the wall, and into a keystone jack. I did some measurements and started to drill a hole in the top plate where I calculated would be in between 2 studs. I used a regular 3/4" spade bit but as I drilled i kept hitting wood as far as my drill bit would go. 1) How deep should I have to drill into the top plate before I get into the wall cavity? I have a much longer flex bit I can use but before I drill further I wanted to ask about the depth. Im not sure if I just need to drill a bit further or if I've miscalculated and am just drilling down vertically into the stud.

I wasn't quite sure where to post this question. Several years ago, I built a clubhouse for my son. I built it on 6 X 6 posts about 12 feet off the ground. A few years ago, I added a slab under the clubhouse to use to store mowers, etc. Footprint of the slab/clubhouse is about 18 x 8. The slab sits in an area that would flood (maybe 3 inches) in a heavy rain if not for the french drains we installed 2 years ago. I intend on dismantling the clubhouse and building a 2-story tiny home. If my drain system should ever fail, I don't want water getting inside the tiny home. I only need the floor to be a few inches above the slab. I thought I would rest my floor joists on a wall of standard bricks placed on the slab, that should give me enough room to stay dry in a worst case scenario. I have a few questions. Should I use something other than bricks? i.e., use PVC joists and rest them directly on the slab. Should I leave the space open between the bottom of the joists and the top of the slab, or enclose the space (bring the siding down all the way)? If I enclose, should I ventilate the space? To assume no water will get under the floor, even if I construct a barrier that's supposed to be water tight, I think is a mistake. My questions are kind of out of order and aren't all applicable depending on the option(s) used. Basically, just looking for advice on what to do on the bottom floor, avoid water getting in.
