IMO, it's a lot like building a house. It's okay to have someone else manufacture the bricks for you. However, you still have to lay them by hand. It's tedious, repetitive, and labor intensive, but gets you the exact result you want. The second you try to pre-cast bricks, you end up with something harder to work with.
