New Framing/Foundation Plan for Existing Addition
 
1 Attachment(s)

I have an existing sunroom off the back of my house, it's 13'8" deep by 17'6" wide. The current "foundation" runs 2/3 of the addition perimeter with one side open to access a partial dug out crawl space; which has an average of 4'6" headroom. The 2x8 joists are unevenly spaced but average 14" spacing. I'm using a trial of SmartDraw and I've attached a jpeg of the drawings.

1" = 4'
The brown is existing framing and the yellow is planned. I basically plan on cladding the rim joists with new 2x8. Creating a 20' beam with 3, 2x10's, glued and nailed. Sitting on 4 6x6 PT posts on metal saddle brackets set into my 18"x18", 6" deep square footings.

I'll also be putting another 2x10 fastened to the house wall under the existing ledger board with 6" Lags offset every 12".

Does this look good? Any comments would be appreciated.

Thanks.

I appreciate all the replies. Here are some pics of the addition, if you want more of the structure let me know.

I'm going to do a new drawing taking into account all the feedback and I'll post it up later this weekend.

Thanks.

Thanks Neal.

I forgot to add that the two PT 4x4's to the left of the last picture are just in there for added support right now.

I was thinking of doubling up the joists already and adding a couple near the far end (spacing is pretty wide), already planned on joist hangars and lag bolting the ledger.

Once I come up with a final plan, I don't think the building permit from the Township will be to hard to get. It's going to be getting permission to dig/move earth from the Conservation Authority.

Here's a couple pictures of the view to show why I chose this crazy investment.
