Regarding the building code: My contractor purchased a window 96'wide
x 93'high, including chapes on the top for a room with a typical
ceiling (8 ft) and for the space 104' between walls. O.B.C. code N
9.7.1.6 (2)(c) says that it should be minimum 1'7" from the floor for
the window in a bedroom. The contractor claimed that he would mount
the shapes under the roof somehow, so you could see them only from the
outside. Could you please tell me was it possible to do it? We already
had truces and all framing finished then, and the truces were on the
way...

hello - 
I am not a google reseacher, and I do not know the particulars of the
code in your area. However, speaking as a builder, generally the
requirement for windows is that IF they are less than 18" from floor
height they have to be tempered glass (for child safety).  So you
probably can have lower windows if you need to, but they have to meet
the stricter (more expensive) code.   good luck to you. - synapse666b
