Scripting those reveal profiles in Grasshopper is the easy part—it's when you measure the actual floor slab deflection on site that the sweat starts. We had to build custom tolerance logic into our workflow last year just to keep a 6mm gap from vanishing under load.

That shadow gap is completely unforgiving if the floor decides to breathe come winter. Did you happen to catch any section details on how they stopped the plaster edge from cracking over time?

That takes an absurd amount of patience from the plasterer to keep consistent across a whole room. Worth every bit of site coordination though, it looks stunning.

My plasterer near Todi nearly walked off the job when I asked for a shadow gap against three-hundred-year-old masonry. We ended up scribing a thin chestnut trim instead, and honestly, the room is much warmer for taking the hint from the building.
