Hello,
I'm thinking about enclosing the upper level of my garage to take advantage of about 1000 sq/ft of space that was wasted as an inherant result of the topography of my lot.
As illustrated in the attached pix, I have an elevated foundation. I want to frame a subfloor in my garage and enclose the upper level.
The Dimensions of the garage are 20.5' W x 30' L. I plan to cut down and hang 2"X12'X22' joists the width of the garage at 16" centers directly at the level of the foundation. This make the floor level the same as the adjacent office and will allow me to make access to the new room from the office by cutting a doorway in the sheetrock directly above the foundation (shown in pix).
I have a couple of questions about how to get started! I think the first step would be to attached the ledger to the concrete foundataion using concrete lags and all thread or bolts with large washers to secure the ledger to the concrete. I will then probably shore it up with some 2X4's from the garage floor to the 2X12 ledger. Is that a correct assumption?
On the other side (left as looking in to the garage from the door), where there is currently sheetrock and I suspect 2X4 studs, I plan to cut out the 12" horizontal strip of sheet rock to expose the studs. My question on this side is, would I put a ledger board flush against the studs and secure the joists with joist hangers as I will do on the opposite side, or would I put 2x4 bracing between the studs and rest the joists on that bracing?
I plan to cut 2X12"x22' down to fit the width of the garage and one of two options to support the center: My first option is to strap the bottom of the joists together using a 2X4 the length of the garage and to use 3 or 4 - 4" diameter steel columns bolted to the garage floor to support the subfloor. The second options to to frame a wall the length of the subfloor and devide my two car garage in half. I prefer the columns as not to take up the space from a wall but will use what is best! Suggestions?
A pool table with 1.5" slate top will eventually reside in this room so whatever I do, will have to be secure!
Am I on the right track here in my construction assumptions? Any planning tools, tips or tricks recommended by the professsionals?
Thanks for your advice and help.
I can take more shots at different angles to support and decisions or questions you made need asnwered before advinsing!
I'm hoping to do this on my own with the help of a few buddies. I am handy with tools, I can read county codes and I have done some frameing in the past, albeit very light work compared to this project. I know this job is quite a few levels more difficult than a typical weekend project but I'm sure I can handle it. I accidentally asked this question in contractortalk.com and was blasted with insults and told I could not do this job on my own and to hire a professional. If that is your position, dually noted and respected but I still need to know the correct way to do this so that I can trust that the contractor has done it correctly.
