I was asked by a viewer, Mike Quantum, on making the triangle used on the Art building. The photo shows the block layout in different colors. The black roof slope stops at the wall and the red slope blocks create the overhang. The granite blocks are upside down and fill the gaps creating the smooth line. The slope blocks were cut in the circular saw from full blocks that are able to be cut by the saw. I will include a short example in the next video.
