Here is my update for the July long weekend, 2016
The shape is so I have a little table to hold my coffee while lounging on the settee
next photo is the shelves inside the settee leanback, and (not shown) one of the access holes was cut in the seatback.
The other bit of progress is the windows. Here is the set by the dinette, each window is just under 18" square. The order of assembly will be, from the outside in, exterior trim, an 18x72" piece of Plexiglas, bedding compound, the 1/2" exterior skin, then a window frame ( which is visible in the photo of the shelves above) cut from a 1/2 thick plywood, glued to the inside of the exterior skin to strengthen the ribs. Inside of this is a second piece of Plexiglas and a final 1/2 frame , screwed together so that the Plexiglas can be replaced when scratched up. I am using the term "Plexiglas" here generically, as I will actually be using whatever brand that my local lumberyard carries. I left the cedar around the window exposed, and will coat it with a clear finish, maybe Prizim as recommended by Dave, if the cost to get it here is reasonable.
Don't pay any attention to the mess visible through the window, once I launch that will no longer be in sight.
