Thank you Jorge.

Environmental controls, electrical, lighting, etc is all covered. As I stated in the OP, there will be no safe.

Though I'm not interested in discussing the details of the construction, rest assured the guns will be secure - I've got quite a clever and practical solution to this concern.

No windows, and the house is very well equipped with electronic security.

I'm really just seeking input on a way to display my guns in a manner that is pleasing to the eye, yet wont harm them.
