@Jack B - I have a Creaility Ender 3 Pro. For detailed work, like your bricks, I would consider a 0.2mm nozzle. You'll need some patience though. I use a 0.1mm nozzle often times, but I can tell you it's not for the faint of heart. I'm thinking you're going to have to lay those walls flat (with the bricks facing up) on the build surface, mainly because of the window openings. The Ender is also great for sign work. Here are some quick pic of signage left overs...
