Currently the room is being used for storage and I got some stuff cleared out which allowed me to get better measurements and to my welcomed surprise I have a bit more room. So, here is the revised space and based on earlier conversations I think this is what the Aisle might look like for doing another concept design within the space.
I won't have the exact location of the interior wall studs yet but I believe I have the approximately placed well enough for conceptual designing. I have also marked off 1" on the exterior walls for supports and backdrop board. The wife and I are still not 100% in agreement on where I might place the Helix in the Family room but right now the conceptual designs will be using the 38x38 space the the left of the Fireplace but keeping in mind I might get the entire 38" depth space all the way to the right of the Fireplace
The Light Blue Walkways are 30" wide all the way through and still thinking a Multi-Deck design with 2 or 3 decks with the scenery focus being rouged Rocky Mountains with little to no structures. Depth of Deck #1 will be between 12" to 24" so View Blocks (also used for Deck #2/#3 supports) will break up the island area accordingly
