We particularly like the rather ingenious diagonal wall that runs down the right side of the building. The rest of this section is spent building walls and adding a plethora of interior details. These are much smaller to accommodate than the mezzanine, but really look the part, providing a forced perspective to make the staircase look larger than it really is. The bannister comes together with a rather ingenious use of Bar Holders with Clips pieces and towards the end of the ground floor build, you tackle the stairs that branch left and right. You build up the walls forming the hidden sections that will ultimately sit beneath the mezzanine before progressing onto the grand staircase. You begin by tackling the 32 by 32-stud baseplate, using lots of grey, square tiles to form the pavement and more tiles to form the attractive checkered tiling on the Sanctum’s ground floor. You start from the baseplate and work upwards the linear nature of the build is extremely enjoyable and as always, the Minifigures are evenly spread throughout. Each booklet deals with one of the three floors. The build is spread across 18 bagged sections, further divided via three separate instruction booklets.
