Well, I've decided to alter my plan a bit.

Instead of building a room in the garage, I'm going to build a dedicated herp building in the backyard.

I've decided on using a custom 8x15 shed as the starting point. The shed will have two double pane 3x3 windows on either side of a fiberglass door.

There will be a total of six outlets, two fluorescent fixtures and a 12000 BTU PTAC unit running off of three 20-amp breakers. The structure will be insulated with both insulation and reflectix and then finished off with wallboard.

The shed is being custom manufactured and should be here by the 22nd of February. Then I figure it should take another two weeks to get all the electrical and finish work completed.

The site location is in a nice shaded area of our yard that even in 100 degree heat stays fairly cool. I'm hoping that this coupled with the reflectix will keep the summer cooling costs down.

Again, as the process unfolds, I'll post pictures.
