so I started by turning these scrap pine stakes into square frames

next I joined them with some more scrap stock and floored it with some basswood paneling

then I finished off and sealed the interior with more basswood panels. I made a door frame from some nice cherry stock I had leftover then papered it with reflective mylar

I found some insulation made of 100% cotton from recycled denim so I stuffed that in and then finished the exterior off with more panels. I gave it a coat of primer and clear coat to keep out moisture

then I placed it back outside replacing his heating pad and blankets. So this is how he'll be spending the winter
