ColJack said:i always wondered...
when they have those bricks with 3 holes in them, why can they not be made so the holes line up when laid? this would make it ideal to put a conduit down to run the cables in the walls..
Difficult as the mortar clogs the holes as it is intended to make a keyed joint between bricks.
if they know the locations of sockets and light switches they could even use special "half bricks" to put the back boxes into whilst building the wall..
I have seen that done
if ever i get enough cash to build my own house from dirt to smoke then I'm gonna look into it..
For self build I would advocate a non brick method.
