Finally starting an addition on our shed

[STx]

Thanks, I'm not all alone, my wife is helping but, it is a lot of work for just 2 people and she has height issues so some of it has to be just me.

The window with headers above and below is a 2 story walk where the window splits the floors. The bottom header is to carry what would have been on the top plate that's going to get cut out.

The exterior walls are all framed in 2x6 so it was easy to just do it all in 2x6.

For the one or two windows that are carrying roof loads, if you are worried you could use header hangers.

Simpson Strong-Tie 16-Gauge 6x Header Hanger-HH6 - The Home Depot

But by the time you bought two of those, you could also have bought 5 2x6x8' for two studs and a header. Sometimes you just have to waste some materials. You can work around that some by using salvaged bits for things like rafter blocking, soffits, eave ladders, and such.

Personally i would redo all the headers to make them right. but to be practical you could only do the load bearing sides.
I also like to square and sheet walls before standing them.

We're not sheeting with OSB, were just doing house wrap covered in 20' pieces of metal siding run horizontally to match the shed we're adding on to. The color isn't perfect but, it's complimentary. We're trying to make it look as little like an addition as possible.

Metal is attached with screws that have rubber gaskets on them. You snug the rubber down to where it begins to bulge out just a little bit. The allows the metal to be snug, but not break the rubber gasket. In no way is this equal to what OSB or plywood does to lock the framing together or stop it from racking. Metal over OSB is the only way to make sure the building doesn't move around on you.

I know, the building we're living in is put together that way, except with the studs on 30" spacing. I'm also planning to notch the inside 2x6 framing and put permanent 2x4 cross bracing into the walls. I just want to get it all dried in first.

Well Eddie, SWMBO vetoed my internal bracing plan so the OSB is on its way. Probably better in the long run, it's just another $750 I'd rather spend in the bathroom...

Only problem with OSB is that the price is at it's peak right now. It seems to go up and down from $14 a sheet, down to $8, and even lower at times. If you really want to get crazy, look at Zip System. It's a higher grade of OSB with a rubberized coating on the outside that is far better then house wrap. After you install it, you apply special Zip Tape to all the seams, which costs $25 a roll. House wrap is OK, but with houses becoming more and more energy efficient, products like Zip System will become more and more common. Besides sealing a house better then house wrap, it allows you to leave it exposed to the elements a lot longer and in my personal case, it allows me to do one side of my house at a time, and work on it as I have the time to put into it. Plus you can get it in longer lengths then 8ft. I buy the 4 x 9 foot all the time, it's able to go from my bottom plates to my rafters and tie everything all together!!!

$15.23/ea. It is pretty high right now, thanks to hurricanes and floods. All the building materials have gone up since August. When I bought it in July, it was about $10/ea.

Drywall is really climbing as well.

Got ceiling joists done the other day, fixing headers this morning.

I know the joists look weird, I have a plan and reason. It's necessitated by where the load bearing walls are and plenum needs for the a/c. Hopefully, I'll get rafter framing started today. I'm not super optimistic though.
