Making the base...

To start off I needed a good strong base for my model. For those that have seen the module it has three distinct elevations. With the construction methods I intend on using I decided to create the room in three parts that I can push together. This will make it easier to store, and make the weight more manageable.

I decided to base the model with MDF. I have plenty and it makes for a good strong foundation. In order to get the elevations needed I'm using EPS insulation foam. I'll refer to the sections of the model as the "altar" section which is the highest, the "pool" section" which is the middle (both in height and position), and the pit section.

The altar section is 5 squares by 21 squares (every square is an inch on a side so I'll probably switch back and forth with my units). It's two levels above the lowest section (the pit). Each elevation is 1" which is a convenient choice when using 1" blue foam.

The middle section is 19x21 and is one elevation above the lowest section.

The pit section is the lowest section. It's 6x21. On either edge is an area that is the level of the middle section. These are 3x6.

So the parts list is:

• Altar
  
  • 1 piece of MDF 5" x 21".
    
  • 2 pieces of foam 5" x 21".
    
  
  
• Middle
  
  
  
  • 1 piece of MDF 19" x 21".
  • 1 piece of foam 19" x 21".
    
  
  
• Pit
  
  
  
  • 1 piece of MDF 6" x 21"
    
  • 2 pieces of foam 3" x 6"

A table saw made quick work of all but the small pieces for the pit:

And the foam cutter easily handled the smaller pieces:
