Modular-aware: the factory-printed module doesn't pay local labor rates, so the regional index applies only to the site scope (foundation, MEP, on-site assembly & finish, local permits). At 55%, New York's ×1.30 index becomes an effective +16.5% on total — not +30%. This share is a placeholder assumption; David to calibrate against the real factory/site BOM split.

How these numbers are derived — methodology & sources
Cost backbone
The Florida baseline is a two-point linear fit to Vertis 3D's own validated V4 project data: a 2,583 sq ft standard home at $239,968 ($92.89/sq ft) and a 1,679 sq ft starter at $196,635 ($117.10/sq ft). That separates a fixed component (site, foundation, MEP base, fixtures) from a per-sq-ft variable (shell, materials, labor, finishings). Source: David's V4 estimator sheet.
Regional indices — sourced, not invented
- New York x1.30 — validated across four independent sources (RSMeans City Cost Index NYC ~131 vs 100 national; NAHB / Home-Cost state averages; TXRAC 2024 $/sq ft NY $211 vs FL $160 = x1.32). Convergence band 1.28-1.32.
- California x1.35 — deliberately conservative. Raw sources put CA $225/sq ft vs FL $160 = x1.41, but CA is bimodal (coastal far higher than inland), so the index sits below the raw average. ADU demand is the live CA angle.
- Florida x1.00 — baseline. FL ~99% of the US national average ($160 vs $162), so it anchors the model cleanly.
Why a 55% region-sensitive share?
A 3D-printed home is part factory module, part on-site work. The factory module does not pay local labor rates, so applying a full regional index to the whole price overstates modular cost. The model applies the index only to the site scope (foundation, MEP, on-site assembly & finish, permits). The 55% default is a placeholder for David to calibrate against the real factory/site BOM split — slide it to 0% for flat-off, 100% for legacy behavior.
Region indices and the site-share split are labeled assumptions pending David's sign-off before this tool is placed on vertis3d.com. Backing research: region-multiplier validation + Florida closeout notes (internal).
