Imperial Fortress

Using this as Inspiration I am building a 2x4 Imperial Fortress which I am going to build as a self supported Table Addition. This would extend whatever table we were playing on by 2 foot in length. This is going to be somewhat involved as far as projects go and due to the nature of it being mounted on a permanent base working on it in modular pieces may be difficult. If anyone would like to help me build this monster or contribute in any other way, please feel free.
