Building block and methods

A column comprising:

• a plurality of the blocks arranged in multiple courses;

• (i) the first bearing face being an upper face in use and having a contact surface portion that is planar;
• (ii) the second bearing face having a contact surface portion that is planar and parallel to the contact surface portion of the first bearing face;
• (b) the first side of the body having a center plane that is orthogonal to the first and second bearing faces, the center plane bisecting the first side between a first section and second section;
• (i) the first section having a first section length and being angled inwardly at a first extension angle relative to a plane orthogonal to the center plane, the first section extending to the center plane in extension from the first end face;
• (ii) the second section having a second section length and being angled inwardly at a second extension angle relative to a plane orthogonal to the center plane, the second section extending to the center plane in extension from the second end face;
• (c) the first end face having a first end face length and is angled at a third extension angle in a direction toward the second end face, as the first end face extends from the first section of the first side to the second side;
• and
• (d) the second end face having a second end face length and is angled at a fourth extension angle in a direction toward the first end face, as the second end face extends from the second section of the first side to the second side;
• wherein the first section length, second section length, first end face length, and second end face length are the same;
• and
• wherein the first, second, third, and fourth extension angles are the same;
• (e) the second side of the body includes a first segment and a second segment with an inset between the first segment and second segment;
• (i) the inset including an inset wall extending between the first and second bearing faces;
• (ii) the first segment having a first segment length extending between the first end face and the inset wall;
• (iii) the second segment having a second segment length extending between the second end face and the inset wall;
• and
• (iv) at least a portion of the inset wall being closer to the first side of the body than each of the first segment and second segment;
• wherein
• (i) each course comprising a block pair, each block pair including a first block member and a second block member with the first and second segments opposing and against each other;
• and
• (ii) each subsequent course having the second bearing face of the first and second block members of the block pair stacked on the first bearing faces of the previous course and oriented 90° relative to the previous course so that the first sides of the block pair in the subsequent course are over the end faces of the previous course.
