The left is a giant Villa. It has a controlroom under the Floor, from where you can control some Lights and all the doors. The Signs are in German (Yes, I'm german :3 ) You have to decorate it by yourself. It's just a shell. The entrace to the Controlroom is in the left room. You can only open it from inside.It's closed now. If you are in the entrace hall, destroy the bottomblock, where the 3 Doors are looking at ;)

The Right one, is a tower. You might know the build-style from one of the videos of AnimationCraftPG5. The tower is not complete, but I will not finish this, cause, I just wanted to upload the Villa, I never wanted to upload the Tower. I don't have World Edit, and I don't wanted to brea the tower down, so I build it a bit higher... and done. Sorry for that ^^"

Take a look with the pictures. Have fun with the Villa :D
