Highland Mansion Wall (Stone)

Taken all the way down to base materials, one Highland Mansion Wall (Stone) is 3 crafting steps deep and needs 7 intermediates — Clear Glass Lens ×15, Holy Cedar Lumber ×15, Roof Tile ×15 and 4 others — which resolve to 12 distinct raw materials totalling 295 units, plus 290 crystals.

That bill outweighs 13,590 of the 13,602 recipes tracked here and 1,436 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 40 of those crystals go into the final step; the other 250 are burned by the intermediates, so the real crystal cost is 90 Water Shard, 90 Wind Crystal, 40 Fire Crystal and 3 other kinds.

The chain crosses four disciplines — Armorer to Lv 60, Blacksmith to Lv 54, Alchemist to Lv 52 and Carpenter to Lv 52 — so no single class can finish it unaided.

All 12 raw materials are gathered, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
