We are going to begin framing our new home next week and need to finalize windows. I have a few questions I am hoping you all can help me with. All windows will be anderson 400 tilt/wash. Sorry, this is long:

1) In the den (which will be used as a playroom but we would like the option to use for an elderly parent bedroom if we ever need it), should we add a second single window to the left wall to make symmetrical, or make the single into a double window? Might affect future bed placement which is why I think we currently had 1 window offset (but now it just looks weird to me!)

2) In the family room, the large window is currently set to be a picture window (DHP5656) flanked by two double hung windows (3056). All double hang windows in the house will have mullions in the upper sash only. Her we set the picture to have no mullions (flanked by the two with upper sash only). Does that sound right?

3) The 4 panel door unit in the nook area also is set to have no mullions- will this look weird wince the other windows have upper sash mullions? The other option is full mullions but they don't do the doors at the 1/2 mullion in our price range. Also, the windows are all set to header height of 8', with 9' ceilings. For the door we can do a 8' door or 6'8" door with transom. Opinions? Window dealer said 8' is better for window treatments. Price is about the same either way.

4) The window over the kitchen sink is being changed to a picture with no mullions (P3040) flanked by 2 casement with full mullions (CN14). I have the same concern with the mullions here. All the other windows are upper sash only but with casement I know things are different. Will it look weird with full mullions? Also what height do you think this should be set at relative to the countertop? With 8' header height, these windows are 4' high which leaves the base at 4'...should we go taller to make the base lower?

5) Also regarding the window over the kitchen sink: we can center on the counter run (13' long) or we can center after excluding the 24" of cabinet that overlaps the perpendicular cooktop wall (the back corner where the pantry is. Not sure if that makes sense but as it is now, it is centered that second way. Preferences either way? I am inclined to leave as is since when you look at that wall head on, it will appear centered (since the cooktop wall will block that small 24" in the corner)

6) The basement is walkout in the back left corner. We can have windows with 3' base along 3/4 of the left and back wall (will be wood framed in these locations). The door has moved and has to be in the corner due to drainage (can be either on the left or back wall) . Any ideas on what windows to use and where? We are not finishing the basement now but want the option in the future. Current windows placed are meaningless. We can do anything. Mechanicals are probably moving to back right corner to vent to backyard. Bathroom is only roughed in.

Here is the full plan and elevation to give you an idea of the overall look (color choice not yet set though). Thanks for the help! I will probably be posting a few more last minute questions before the framing behinds! Getting excited/nervous.
