| # Slab to Sale |
|
|
| Slab to Sale is an interactive pre-construction feasibility tool that compares conventional home construction with a 3D-printed-wall scenario from foundation through finished-project economics. |
|
|
| ## What it does |
|
|
| - Compares conventional and 3D-print construction schedules |
| - Estimates full-project cost, financing impact, and profit range |
| - Calculates break-even printed-wall pricing |
| - Models optional printer ownership payback |
| - Surfaces bottlenecks, permit assumptions, and data provenance |
| - Uses transparent public, vendor, commercial, and user-entered sources |
|
|
|
|
| Premium static Hugging Face Space comparing conventional construction and 3D-printed-wall scenarios. |
|
|
| ## V11 motion upgrade |
|
|
| - Hero house now visibly prints itself layer by layer |
| - 3D perspective side wall and roof slope |
| - Moving printer gantry and nozzle |
| - Roof, openings, plumbing/electrical traces appear in sequence |
| - Looping construction status pill |
| - Finished-house fallback for reduced-motion users |
|
|
| ## Existing sourced-data features |
|
|
| - Data provenance badges throughout the configurator |
| - RentCast-ready property-value fields, without exposing an API key |
| - FHFA House Price Index source link for market context |
| - U.S. Census Survey of Construction source for future duration benchmarks |
| - Census Building Permits Survey source for market permit activity |
| - BLS Producer Price Index and operator-wage references |
| - FRED prime-rate benchmark separated from editable lender spread |
| - Modeled construction APR calculated transparently |
| - ICON vendor pricing source on printer purchase price |
| - RSMeans / Gordian marked as a future licensed cost-data source |
| - User/lender inputs explicitly separated from public and vendor data |
| - Dedicated Data Provenance section showing connection status |
|
|
| ## Important |
|
|
| V10 is still a static Space. Source links and benchmark snapshots are shown transparently, but most sources are not fetched live. Commercial APIs that require keys should be connected through a backend rather than exposing secrets in `index.html`. |
