the way its framed on the outside u can buy some 1.5" foam to stick in between the boards, then get you some kind of nice lookings thin wood to stain and nail/glue it on, a litte trim work around the window and have a nice pc of furniture
a finished product with some 1/4" wood (bamboo in this case) stained. and the glass in, altho i did the glass @ 3/4", not a big deal for a mock up. and some clear hood covers that are 1/4" thick also
