Things to look at...where does the pipe come from and where does it go. Ditto with the cable. If that is a water heater I see in the right margin, you can elbow the copper up and over the door header and eliminate the drop back down by just re-running it to the water heater. The cable must either be re run completely or two junction boxes must be installed on either side of the door with the cable going up and over like the pipe, just not in the same holes. Again, where does it go and what does it service. If it is a home run of 12-2 on a 20 amp receptacle service, you could install two receptacles on either side of the new door eliminating the need for the junction boxes as the j-boxes must remain on the surface and accessible.

Below is a link to a picture of a barn sash window being inserted. The technique used in this installation only allows the window to be tilted inward a little bit, or removed entirely. I am trying to figure out how to frame and trim the same window, only half the size, so it will swing outward, either on two upper hinges or on two side hinges. The window is 1 inch thick, white pine. Thanks for the response.http://www.barnsbuilt.com/images/sash-window-200.jpg
