Removing, while keeping, a window

Question from Marie: 

Hi Jake, 

We are planning to install built in cabinetry in our dining room. In order to do this we will be sacrificing a large 40"x60" window. We would like to panel over the window so you do not see it from the interior, but still see the window from the exterior so that the exterior wall still looks balanced. What can we cover the window with so that the paneling isn't seen from the exterior? I assume we cannot just leave the pleated, honeycomb shade between the new wall of cabinets and the window. What would you suggest? Thanks  

Jake's answer: 

Marie, 

We have covered windows in the manner you are suggesting. We took a pre-finished white board, like melamine (MyWhiteboards.com). On the interior side, you might have to install some cross braces behind the melamine board so the board does not warp. From the exterior, it looks like a shade is drawn. On the interior, remove the window trim and if necessary, install drywall flush with the window jamb. Then install drywall tape at the joints, tape, fill and sand. The down side of doing it this way is if the melamine board, because of heat or moisture, might not perform. If you are in a direct sun exposure, I don’t suggest you do this. Another option is to remove the window, install new siding on the exterior, install window trim as if there is window, then install shutters in between the trim so it looks as if there is a covered window behind the shutters. This will provide the relief you are looking for on the exterior.
