It depends on your personal preference, but I would do the same as above, only instead of the Cut faces tool, I would use the Split Polygon tool for more control over the exact placement of your "bricks". Then, select the individual brick faces, and extrude/tweak to taste.
Takes a bit longer than the Cut Faces technique, but it gives you "brick" level control of detail....
