Houdini - Hitting a brick wall

I've been wanting to get into Houdini for a few months now and I finally had some time to dive in. A friend of mine told me to start with a goal in mind and something simple, like a brick wall. And although it sounds simple (I'll have an entire building for you in Maya in minutes 😅) building it procedurally in Houdini requires a bit more more forethought.
