OK, Gotcha. Now that it is easy to see then the W3 at the main bedroom is correct, the window size for the kitchen (Noted now as W3A because of size change) will need to be reduced to match the same window edge distance from the corners of the wall. I would also say for asthetics that the size of the W4 windows will need to keep the same distance from the window edge to the wall corners. Sound OK?
