This is how the framing around the window should be (by code which is the minimal standard):




That double plate above the window window roigh opening should be at least a 2X6.

You'll also need to sister a full height 2X4 to the left and right of the window framing between the sole plate and double plates.

Looking at your photo, you can cut out the framing around the window and build/install/nail this configuration in.

Also, I would highly suggest/recommend that you install two top plates.  After a close review, as good of a job as you've done to date, you will run into problems when you get to the point of hanging drywall/sheetrock/gypsum wallboard. 

When you do start, begin at the outside wall since that's the shortest amount of vertical area/stud area to secure the drywall to.

There isn't what is considered to be much of a nailing board.  What are you going to use to finish the walls/ceiling with?

Also, the framing/rough opening around the door should be very similar to the drawing above.

Again, you're doing a great job.  But from a contractor witrh a strong architectural background, you're cutting yourself short.

Measured the window height and the base of the window is 3.5 ft from the ground. Guess a bench is getting put in front of the window...

How much can you hear what goes on in the basement?
For as much as you make access to get out, you make access to get in?
I would install some type of alarm to the window that would sound in the master bedroom and the main part of the house. This would serve more purposes then just one.

Craig,

These are non-load bearing walls. Does the code still apply?
