Sources

Every dimension the house is generated from is below, with its class and its citation. This is the project’s honesty layer, and it is given a room of its own because a smooth 3D render implies a precision the sources do not have.

Which of these matters most

Nearly every dimension on this page is the author’s own. What the provenance bar does not say is whether that matters. Each row below is computed by rebuilding the house: one dimension is pushed 20%, and the house is measured to see how far it follows. Nothing is estimated — the figures are the difference between two runs of the generator.

1. 1rows3.30 mwidth of the house
2. 2bayLength2.95 mlength of the house
3. 3bayDepth1.32 mwidth of the house
4. 4ridgeRise0.85 mridge height
5. 5aleBola0.61 mridge height
6. 6awaBola0.54 mridge height
7. 7timpaRise0.37 mheight of the topmost board
8. 8stoneHeight0.06 mridge height

If only one dimension could be surveyed, this is the one. This is sensitivity, not uncertainty: it shows what moves, not how likely the value is to be wrong. The 20% is itself the author’s choice.

Invariants

There is no measured drawing yet, so correctness rests on structural truth. These checks fail the build.

• pass
  Bilateral symmetry about The building mirrors about z = 0, the plane the ridge runs along

  1112 points; largest mirror deviation 0.00 mm.

• pass
  Every tenon contained in its mortise

  86 pasak, takik and tumpu joints; every one engaged.

• pass
  No joint spans more than one stage

  Every joint engages two parts from the same stage or from consecutive ones.

• pass
  Stage ordering, and nothing below ground

  116 parts, every one bearing on something already standing or on the ground.

• pass
  Mesh integrity: indices, triangles, normals

  184 triangles; indices in range, none degenerate, every normal unit length.

• pass
  The rank boards hold nothing up: take them all off and the house still stands

  10 boards across two gables, not one of them jointed, every one outside the roof plane — and every structural check still passes without them. It is the only check in this project whose subject is what a part does not do. A rank marker that carried load would be a rank nobody could lie about; its whole force is that they can.

• pass
  The board count is odd, and within what the household is entitled to

  5 boards on a Saoraja, within 5–9. That limit is not a limit of the building: a bola would carry seven boards without noticing, and what stops it is that seven is not its to claim. It is the only bound in this project that refuses a number the building could perfectly well take.

• pass
  The stack climbs the gable rather than overflowing it

  5 boards, narrowing to 3.86 m and stopping 2.40 m below the ridge. Each board's length is taken from the gable rather than declared — so seven boards on a small house still read as seven boards.

• pass
  Three worlds stacked, and the highest is the one that feeds the household

  An awa bola of 2.71 m for livestock and work, an ale bola of 3.07 m for people, and the rakkeang above it for rice. The tongkonan divides into three as well; the difference is what is put at the top.

• pass
  The beams pass through the posts rather than sitting on them

  36 threaded joints. The frame is assembled and pegged rather than nailed — which is why this house can be lifted off its stones and carried away whole, and is. A building you can move is not a building tied to a plot.

• pass
  Thatch courses lap with no bare band, from the eave to the ridge

  23 courses over 6.37 m of slope.

• pass
  Every part declares the dimensions it came from

  116 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 116 interpolated.

• skipped
  Checked against a measured drawing of a real house

  Skipped. No measured drawing has been wired in, so there is nothing to compare against. This check will not be made to pass by weakening it.

What a check is preventing

Ten green rows are not a reason to believe anything. So one check is run against a house built to break it, and what is printed below is that check’s own verdict rather than a description of it.

Raise each board and nothing about the house changes: its frame, its roof, its three worlds and every clearance are exactly as they were, because the boards carry nothing and nothing carries them. What gives way is the stack itself — it climbs the gable it is riding until there is none left. The household’s claim, made taller so it can be read from further off, ends with no triangle to sit on. Ten houses, ten rules that cannot be carried out. What is particular here: the failure is purely rhetorical. The building is untouched and would stand for a century, and the only thing that has broken is a statement about who lives in it.

The second house is never rendered. It is built during the build, failed, and thrown away.

This bar moves as real surveys are wired in. That movement is the project's progress metric.
