Hingan Mansion Wall (Kura-zukuri)

Taken all the way down to base materials, one Hingan Mansion Wall (Kura-zukuri) is 3 crafting steps deep and needs 6 intermediates — Clear Glass Lens ×15, Felt Lining ×15, Hardsilver Ingot ×15 and 3 others — which resolve to 10 distinct raw materials totalling 330 units, plus 405 crystals.

That bill outweighs 13,598 of the 13,602 recipes tracked here and 1,439 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 40 of those crystals go into the final step; the other 365 are burned by the intermediates, so the real crystal cost is 185 Wind Crystal, 105 Water Shard, 75 Lightning Shard and 2 other kinds.

The chain crosses five disciplines — Armorer to Lv 68, Carpenter to Lv 68, Goldsmith to Lv 56, Weaver to Lv 42 and Alchemist to Lv 28 — so no single class can finish it unaided.

9 of the 10 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
