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. 1apexRise3.40 mapex height
2. 2storeyRise1.96 mtop floor height
3. 3baseRadius1.23 mbase radius
4. 4postRadiusShare0.76 mring of posts

6. 6luturRise0.25 mliving floor height
7. 7bellyPeak0.09 mliving floor radius
8. 8coneBelly0.05 mliving floor radius

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 a vertical plane through the axis

  21374 points; largest mirror deviation 0.00 mm.

• pass
  The house repeats every one segment, which is every 60°

  19903 points (145 of 161 parts); turned 60° the largest deviation is 0.00 mm.

• pass
  Every tenon contained in its mortise

  31 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

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

• pass
  Mesh integrity: indices, triangles, normals

  28200 triangles; indices in range, none degenerate, every normal unit length.

• pass
  The plan is round: as wide one way as the other

  12.42 m × 12.42 m, differing by 0 mm — as round as a 48-sided polygon can be (27 mm). No face, no corner and no ridge.

• pass
  The thatch reaches the ground; the whole building is roof

  The lowest course meets the ground at 0.03 m. No wall, no eave, and nothing holding it up off the ground.

• pass
  Nothing stands through the cone, at any height

  3577 points tested against the cone at each one's own height; the closest comes within 0.00 m of it.

• pass
  Five named floors, each narrower than the last because the cone narrows

  lutur → lobo → lentar → lempa rae → hekang kode; from 5.98 m at 1.25 m to 2.53 m at 11.05 m.

• pass
  One centre post runs through all five floors to the apex

  from 0.17 m to 17.02 m, passing through 5 of 5 floors. No single member in any other house here touches every storey.

• pass
  One segment per household, and the whole house divides evenly by it

  6 households → 6 partitions, 6 ring posts, 24 rafters and 48 mesh facets — every one a multiple of 6.

• pass
  Niang gendang: the drum hangs inside

  The drum is present, hung 2.77 m above the lutur floor.

• pass
  One door that is actually open, and it is the only direction this building has

  0.95 m wide on a bearing of 0°, facing the compang; the thatch is cut back 1.20 m to a height of 1.88 m. A round form holds no direction; this door is what states it, and there is one.

• pass
  Thatch courses lap with no bare ring, from the ground to the apex

  101 courses over 18.18 m of outline; smallest lap 0.8%.

• pass
  Every part declares the dimensions it came from

  161 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 161 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.

Five floors is canon, and the cone is where all five of them stand — so the two are not independent. Space the storeys further apart and the topmost climbs into a part of the building too narrow to be a floor, or past the point of the cone altogether. Nothing is zeroed and nothing collapses: the building runs out before the floors do. A rule that cannot be carried out rather than a rule disobeyed — and after four houses, that appears to be how these buildings actually fail.

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.
