The importance of finding a good qualified framer just cannot be over stated.A truly good framer will show up to start work and the first thing he should do is check your foundation to make sure it is square and all your support piers are in place, after verifying all is right he can then begin to work.
This is a picture of foundation being inspected by the framer.
Now that we have passed our inspecton we can lay the plywood and begin to build our walls, simple so far.There are so many issues on building walls so far as code goes we can not even begin to go over eveything that you need to know to frame correctly here.The basics you need to know are wall heights, spans for window and door opennings,or whether you can conventional lumber or do you need to use engineered lumber for your headers.
This house was built using convential stick frame methods.
The same rules apply for second floor walls as the first floor walls.We now move on to the roof framing, this can vary a lot by the locaion of were you are building.The roof is absolutely the most difficult aspect of framing, especially if you plan on stick framing, that is if you are not going to be using ready to install trusses.Trusses are pre-manufactured rafters that have designed by an engineer and laid out so that even the most novice of framers can do, I personally prefer stick built, but there is a steep learnig curve and years of expeience needed for this type of roof framing.The benefits of stick built rafters are usualy more attic space and appearence,trusses are usually 24" on center ,where stick built is 16" on center so you don't get that wavey look when you look up at roof.
The framing is done, you can now move on to your other trades.
