This is something I built for myself in my hidden underground base, but could fit into anyone's large build. It's an enchanting library complete with enchanting table and bookshelves. On first glance it looks like a nice place to sit down and read, yet hit the lever just behind the enchanting table (be sure to stay near the table itself) and poof! your enchanting table is now max powered and very private. Great if you want to enchant with low end enchants and later do a high end without picking up and putting down bookshelves.

Additional Notes

If you import it and the enchanting table has no texture (all black), just break the table and put it back down.
Remember, do not put anything in the area around the table (not even torches) for they block the power feeding into it.
