This is what it started as, and where it has gone to...
The external sides are sanded, 4 runs, down to 240 grit. Then stained and Polycrylic sealed.
1/2" thick Lexan windows, on tracks, with a center slide lock.
There is 5.25" inches underneath the enclosure, before the storage area, in which the UTH (Flexwatt Tape) are attached. The tape elevated-mounted by 1/8", to allow airflow between wood and element. Internally, there is 24' of white rope light, which is on a 12 hour timer. A radiant heat panel above provides added heat-insurance for ambient temps on warm side, and that will be internally-roof mounted. The inside is tiled with a terra cotta tile and silicone adhesive, with substrate also.
It is made of 5/8" B/C grade plywood. 1" x 1" structural pieces for adding strength to the exterior. It has the following dimensions:
It has a 10" elevated stand, which will allow for storage or heating elements(to keep off the tile floors).
The enclosure has one vent each side. The outside of the enclosure is sanded and stained with a water based polyurethane, for looks of course.
I decided to look into wood decor from the local forest preserve. Found what I wanted, brought it home, and baked it, sanded it, and sealed it in polyurethane. It worked perfect!!! Bought some cheap silk foliage from Old Time Pottery and placed it in the enclosure.
And the most recent photos are up the previous replies, and shows the final look to the inside of the enclosure.
