1. A method for building a multistage wall comprising:
a. providing:
i. a plurality of first blocks, each of the first blocks having first and second spaced apart side walls defining a hollow core therebetween and at least one groove is formed in a top surface of the first side wall of the first blocks;
ii. a plurality of second blocks, each of the second blocks having first and second spaced apart side walls defining a hollow core therebetween, the first blocks being taller than the second blocks; and
iii. a plurality of bridges to connect between first and second blocks, wherein each bridge has a bridge body and two ends, a first clip contiguous to one end of the bridge, the first clip being shaped to snugly fit onto the first side wall of one of the first blocks in the groove formed therein, a second clip contiguous to the other end of the bridge, the second clip being shaped to snugly fit onto the first side wall of the second block, wherein the second clip overlies a top surface of the first side wall of the second block;
b. positioning a portion of the plurality of first blocks to form a course of a first wall, the first side walls of each such block being on the same side of the first wall;
c. positioning a portion of the plurality of second blocks to form a course of a second wall such that the first side wall of each second block is facing the side of the first wall with the first side walls of each first block, the second blocks being spaced by a pre-determined distance from the first wall; and
d. placing the first clip of one of the plurality of bridges snugly into the groove of each first block and the second clip of each such bridge snugly onto the top surface of the first wall of the adjacent second block, the pre-determined distance being such as to enable the clips to be positioned in this manner, and wherein the combined height of first side wall of the second block and the second clip when in position on the first side wall of the second block matches the height of the first side wall of the corresponding first block.
