I have followed the legendary building channels Grian and FyreUK. I have studied their work and have built a replica (modified for my needs) of Mumbo Jumbo's Drone Base. Cant get an image for you, will try later. I also can use command blocks to animate builds e.g. opening castle doors at the stepping on of a pressure plate.
