Getting stone into the room
A short run of external steps before the communal door means a piece is lifted twice before the staircase proper has even started. Panels travel on edge in a frame, and the frame needs the same clearance the finished piece does. A tall panel cannot be tilted to clear a turn, so it is sized not to need to.
Visitor permits are issued to the household rather than to the trade, so the ones the day needs come from the customer and are best in hand the week before. Where the carry is long the panels come in on edge, two hands on them and nothing else in the way. Handling is where these pieces get damaged.
