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.
The dimensions
| Dimension | Value | Class | What it means |
|---|---|---|---|
| 0.86 mIf 20% out: 0.17 m | Interpolated | Height of a body seated and folded, from the seat to the crown. This is a measurement of a person rather than of a building — and it is not taken from a book about Minahasa but set by the author, like the body figures in the Bali pack. The difference: there the body is living and standing. | |
| 0.62 mIf 20% out: 0.12 m | Interpolated | Depth of a body seated and folded, from the back to the knees. | |
| 0.46 mMoves no measurement | Interpolated | Width across the shoulders. | |
| 0.12 mIf 20% out: 0.05 m | Interpolated | The space left around a body inside the chamber. A box that fits exactly is a box nothing can be put into. | |
| 0.12 mIf 20% out: 0.05 m | Interpolated | How much height the chamber gains for each further person — a hand’s breadth rather than a body, because earlier remains are moved aside and take far less room than a whole body does. A family adds to the same box over generations, so the chamber has to have been cut deep enough at the start for the ones who are not dead yet. A rumah betang lengthens by a room each time a household is added; this one grows upward, and its growth cannot be seen from outside. | |
| 0.16 mIf 20% out: 0.06 m | Interpolated | Thickness of the stone wall of the box. | |
| 0.18 mIf 20% out: 0.04 m | Interpolated | Thickness of the base of the box, cut from the same block. | |
| 1.90 mMoves no measurement | Interpolated | Height of the largest block the quarry gives. A hard limit rather than a choice: a waruga is cut from one stone and never jointed, so how many people it can hold is bounded by how large a stone there is. It is what this building’s counterexample pushes. | |
| 0.42 mIf 20% out: 0.08 m | Interpolated | Rise of the lid above the mouth of the box. The lid has the shape of a roof: a house nobody enters is still made to look like one. | |
| 0.09 mMoves no measurement | Interpolated | How far the lid oversails the box, which is what puts rain outside its mouth. | |
| 0.05 mMoves no measurement | Interpolated | Depth of the rebate the lid sits in. The lid is lifted and put back; there is no other joint in this building. | |
| 0.22 mIf 20% out: 0.04 m | Interpolated | Height of the base slab. | |
| 0.14 mMoves no measurement | Interpolated | How far the base slab stands proud of the box. | |
| 1Moves no measurement | Canon | This building is for the dead. The other twenty-one in this project are for the living, for rice, or for a council; nobody enters this one and it is used for nothing. The lid is lifted, the dead are put in, and the lid is put back. | |
| 1Moves no measurement | Canon | The dead are placed seated and folded, so the chamber is measured against a seated body rather than a standing one. A Balinese bale is measured against its living owner’s body; this is the same principle on an entirely different occasion. | |
| 1Moves no measurement | Canon | A waruga faces north, the direction the ancestors are said to have come from. A tongkonan also faces north for a different reason; two buildings with the same compass rule and two unrelated reasons are a reminder that what is interesting about a rule is not its number. | |
| 1Moves no measurement | Canon | The box and its lid are cut from stone with no joint between materials: no timber, no lashing, no iron, no second substance. This pack’s material list has one member, and it is the shortest in the project. | |
| 1Moves no measurement | Canon | One box holds several of one family, added over generations. This building gains occupants without gaining size — so it has to have been large enough on the first day for the people who have not died yet. |

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.
- 0.17 m
- 0.12 m
- 0.08 m
- 0.06 m
- 0.05 m
- 0.05 m
- 0.04 m
- 0.04 m
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.
- passBilateral symmetry about Symmetric about the north–south plane, z = 0
88 points; largest mirror deviation 0.00 mm.
- passEvery tenon contained in its mortise
1 pasak, takik and tumpu joints; every one engaged.
- passNo joint spans more than one stage
Every joint engages two parts from the same stage or from consecutive ones.
- passStage ordering, and nothing below ground
11 parts, every one bearing on something already standing or on the ground.
- passMesh integrity: indices, triangles, normals
0 triangles; indices in range, none degenerate, every normal unit length.
- passThe chamber takes a seated body, with room around it
A 0.86 × 0.70 × 1.22 m chamber against a seated body of 0.62 × 0.46 × 0.86 m. A Balinese bale is measured against its owner’s living, standing body; this is the same principle on an entirely different occasion.
- passIt all fits in one stone
A 1.40 m box cut from a 1.90 m block, for 3 people. A family adds to the same box over generations, so what limits how many it can hold is not the family but the stone.
- passThere is no way in
Zero doors, zero windows, zero gaps. The lid is lifted and put back, and that is the only opening this building has ever had. The honai is the only other building here with no window; it still has a door.
- passOne material, and no joint between two of anything
11 parts, every one stone, cut from a single block. This pack’s material list has one member — the shortest in the project — and the only thing resting on anything else is the lid.
- passThe face is to the north
The direction the ancestors are said to have come from. The tongkonan uses the same compass rule for an entirely different reason, and on a real waruga this face carries the carving of what the person did in life — a carving this model does not have.
- passEvery part declares the dimensions it came from
11 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 11 interpolated.
- skippedChecked 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.
Give each further person a little more room and nothing about the building goes wrong: the chamber still takes a seated body, the lid still fits, the face still looks north, the walls still close. What happens is that the whole thing no longer comes out of one stone — and a waruga is cut from one stone, never jointed. The Baduy house runs into the length of a pole and the woloan house into the length of a lorry; this one runs into the size of a block, and what takes it there is the one thing nobody can plan for: how many of a family there turn out to be.
The house as built
Rear prow raised to 0.16 m
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.
