Riviera House Wall (Composite)

Taken all the way down to base materials, one Riviera House Wall (Composite) is 3 crafting steps deep and needs 4 intermediates — Steel Joint Plate ×10, Steel Nails ×10, Walnut Lumber ×5 and 1 other — which resolve to 4 distinct raw materials totalling 105 units, plus 142 crystals.

That bill outweighs 13,478 of the 13,602 recipes tracked here and 2,179 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 32 of those crystals go into the final step; the other 110 are burned by the intermediates, so the real crystal cost is 86 Fire Shard, 30 Ice Shard and 26 Wind Shard.

The chain crosses four disciplines — Goldsmith to Lv 36, Armorer to Lv 27, Blacksmith to Lv 27 and Carpenter to Lv 25 — so no single class can finish it unaided.

All 4 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
