1.  Building the foundation was accomplished by gluing two foam sections together, I used these since they would not really be seen in the final product anyway.  You need to have some visual idea to work with.  From there its like putting pieces of a puzzle together.  In this puzzle you have to make all the pieces. I continued building upward using smaller shapes.  The rocks are formed by bending wire to various shapes.  The Router, sculpting tool, pro-knife and engraving tool are used extensively throughout.

2.  The entry way is carved and various stones and brickwork are etched.  The individual shapes go together to form a solid structure.

3.  The front wall is made in the same manner.  The exposed brickwork is made by cutting out uneven shapes and etching in the bricks.  The video has excellent tips for this kind of work.

4.  Details of many shapes, sizes, and depths are made with minimal tools and fuss.  I highly recommend these great products to beginners and pros alike.  The more you experiment the more you discover.  A lot of techniques I used were done on the fly, testing them out on a piece of scrap foam.

5.  The whole thing continues to go together.  Look how easily the grooves are cut to accommodate the balsa "timber".  The surface is roughed up foam.  Cool effects can also be achieved by mixing Foam Coat with your favorite paint before applying.
