The Brick Wall

If we make the loose analogy that the act of building is similar to language, we quickly turn to comparing building components, the brick, wall ties, flashing, walls, etc to grammar and syntax. To extend this further, we could paraphrase a Wittgensteinian question: "What would the brick wall be, without the wall?" Is it just a brick? or is there something between the brick and the wall that changes it, and like a 'wink' with multiple possible meanings, transforms the combination in context into something else.
