There is described a building block set which comprises at least two block types formed by base blocks and/or joined base blocks comprised of a united combination of identical or different base blocks, a first base block having a portion in the shape of a straight rectangle parallelepiped which is extended at the one end thereof by two flanges each extending in the extension of a side surface or said portion over a distance substantially equal to a fraction of the length of said portion, the parallelepiped-shaped portion having a hollow volume extending through the block over the whole height thereof, a second base block the horizontal cross-section of which is fork-shaped, particularly U-shaped, the flange length of said second block being substantially equal to the flange length of the first base block, the tolerances allowed for the above-defined lengths and distances being substantially equal to the thickness of the walls of the parallelepiped-shaped portion, the lower and upper edges of each block type being substantially flat to allow laying the blocks without anchoring on top of one another in any relative position whatsoever.
