Thanks for the input guys
I own a construction co so I have access to everything i need to build it.

Zandor i am thinking about 2 rooms. I am going to leave the big swinging door but build a wall just inside with a regular walk through door.

Insulate the inside with a layer of this http://www.insulation4less.com/highr_FBF.asp
and a layer of ridged foam. That should give me a good thermal break so heat will not transfer.

I may paint the top white. Not sure.

I think my first concern would be ventilation. This thing is pretty tight. I think I have the AC and heating part figured out.
I am sure I can control the temp and humidity pretty well but fresh air may be an issue.

I am thinking two 1000 watt on light rail. I own one now so I would just have to buy or build another light set up.

All the electric and water lines will go under ground and up through the floor so no one will see them.

Turtle i thought about doing just what you said but then i would need windows and people would be walking up to it and knocking etc. so i decided to leave it looking like a storage unit.


Any other suggestions?? I am still troubled by the ventilation issue.......
