         10 . The attachment system of  claim 7  wherein the plurality of first wall sections, the plurality of second wall sections, the plurality of substantially horizontal planks, and the plurality of rods are removable from one another. 
     
     
         11 . The attachment system of  claim 10  wherein each of the at least one hole in the plurality of substantially horizontal planks has a tube contained therein, wherein the attachment system further comprises at least one washer, each washer passing through one of the plurality of rods, and wherein said tube is filled with a filler. 
     
     
         12 . The attachment system of  claim 11  wherein the filler is one of: lightweight concrete and concrete grout; wherein the plurality of rods are threaded; and
 wherein each rod further includes a second washer and a second nut fastened onto the rod above a top surface of the plurality of substantially horizontal planks. 
 
     
     
         13 . The attachment system of  claim 1  wherein the plurality of first wall sections have interlocking edges. 
     
     
         14 . The attachment system of  claim 8  wherein the plurality of first wall sections and the plurality of second wall sections have interlocking edges. 
     
     
         15 . The attachment system of  claim 13  wherein the plurality of substantially horizontal planks have interlocking edges. 
     
     
         16 . The attachment system of  claim 15  wherein the interlocking edges comprise a first portion and a second portion, the first portion being offset from the second portion such that the first portion of a first interlocking edge is in contact with the second portion of a second interlocking edge. 
     
     
         17 . An attachment system for use in a building, the attachment system comprising:
