This is my first post on this site. I've bought a brand new raised ranch in July with an unfinished 25'x30' room that I wish to turn into a pool room. A 9' table requires a 15'x20' open space, which can be satisfied. I have little construction history, but I am very handy, and I don't doubt that I can do all of the work myself. I just need your help in discussing pitfalls and advice that come from the experience that I don't have.
I've started by taking a panaromic picture of the room and using Microsoft paint to create an artists conception.
The room is unobstructed (LVL beam) with one wall grade level, two walls 4' high concrete, and one sharing with the garage and stair well. The water table is low enough not to be a problem, and the room remains dry except for a small amount getting through a settling crack (maybe half a cup during a very heavy rain). I will need to seal the crack, maybe from both sides. I first thought about using Dricore to make a floating subfloor, but found a product called SuperSeal that I like better for the price (no plywood needed, high compression strength). Plus if flooding does happen, no plywood to rip up and throw away: just remove the carpet, and possibly dry it out and save it.
I know I have to use pressure treated wood for the baseplates, and since I'll be making the structures for the buildouts and wainscoting myself I'll build it stick by stick and toe-nail the boards (instead of building on the floor and having to shim). I know I need to add foam against the concrete, and fill all holes with foam insulation before adding pink stuff. I'll do all the wiring myself, and add a black tiled drop ceiling.
So that's the plan. I don't know what I don't know
