Dutchman · Public Demo

Pick a house. Move a wall.
Watch the price.

A working preview: a curated design catalog and a live parametric engine where the drawings and the budget come from the same geometry, so they can never disagree. Try to make them disagree. It will refuse.

Live geometry · one model drives every view and every number
Plan · derived
Front elevation · same model

Not just sliders. The model carries rules. This button tries to save a design change that breaks the geometry, and the engine refuses to let the drawings lie.

Total area (derived)
Shell materials

Every quantity is computed from the wall geometry above, not estimated. Line deltas show the cost of your edits against this design's baseline. Planning-grade unit costs (Edmond OK); real quotes replace them in the full product.

The deliverable. During a build, Dutchman issues a one-page report at each phase gate: what the data confirms, what changed, the few items worth a glance, and its own printed corrections. Below is a realistic sample with invented contents.
BUILD PULSE — [Builder] · [Lot] · Gate 3: Dry-in  |  Sep 8–26 · Issued Sep 27 · SAMPLE
The one-paragraph read

The build reached dry-in two days ahead of baseline. Photos confirm the frame matches the plan in layout and opening count, and delivered roofing matched our takeoff within 3 percent. Two items worth a glance below; one is probably just a supplier substitution.

Confirmed
  • All 14 first-floor openings present at drawn positions. CONFIRMED
  • Dry-in complete Sep 24, two days ahead of baseline. CONFIRMED
  • Roofing delivered: 31 squares vs. takeoff of 30.1. CONFIRMED
Worth a look
  • QUESTION Window grids in Sep 22 photos read 6-over-1; the elevation drew 4-over-1. Substitution or supplier change?
  • LIKELY Framing finished 4 days behind, but downstream milestones are unchanged in the Sep 20 schedule. Recovery planned, or update pending?
Corrections

Gate 2 flagged a "missing" porch beam; your Aug 30 photo showed it staged in the side yard, not absent. The photo review now checks staging areas before flagging absence.

Next period

If schedule holds: housewrap complete, windows set, mechanical rough underway. One optional ask: a photo of window labels at install settles the grid question.

Observe-only. Nothing here is an instruction, an inspection, or a code determination. Corrections improve the next report and get printed in it.
Behind the curtain. In the finished product you'd never meet these ten — you'd talk to one guide named Dutch, and these ten would work backstage. This tab exists so you can see what that guide actually has on staff.

Hard boundaries, by design: agents draft, audit, and alert — you sign everything. Stamped drawings, engineering, and code rulings stay with licensed professionals; the agents route to them, never around them.

Tell us what you think

Three questions we're testing: What works? What's confusing? What would you need to see before trusting this with your own build?
