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 |
|---|---|---|---|
| 9.60 mIf 20% out: 1.92 m | Interpolated | Width of the lowest floor, across. It is the smallest floor in the whole building — the only building in this project of which that is true. | |
| 12.40 mMoves no measurement | Interpolated | Length of the lowest floor, along the ridge. | |
| 2.70 mIf 20% out: 2.16 m | Interpolated | Height of one storey, floor to floor. | |
| 0.55 mIf 20% out: 0.66 m | Interpolated | How far each floor projects past the storey below it, on all four sides. This is the figure that inverts this building’s silhouette against the other twenty-five here. | |
| 0.05 mMoves no measurement | Interpolated | Depth of the hollow in the stone the foot of a post sits in. Without it a post only touches its stone on one plane, and a joint whose members do not enter each other holds nothing. | |
| 1.95 mIf 20% out: 0.39 m | Interpolated | How far a pale can reach out from the frame of posts. Each storey projects further than the one below it, so the longest arm is always the topmost one: this building’s limit is set at its top. It is a carpenter’s figure rather than a rank figure — and because the two are independent, a projection demanded by standing can pass what an arm can carry. | |
| 0.14 mMoves no measurement | Interpolated | Section of a bracket arm. | |
| 1.90 mMoves no measurement | Interpolated | Spacing of the brackets along one side. | |
| 0.20 mMoves no measurement | Interpolated | Section of a principal post. | |
| 0.30 mIf 20% out: 0.06 m | Interpolated | Height of the stone under a post. Nothing is buried: the whole frame stands on stones and is held by its own weight. | |
| 1.35Moves no measurement | Interpolated | The outer stones are set a little wider than their posts, to spread the load of a building that leans outward. | |
| 0.18 mMoves no measurement | Interpolated | Depth of a floor beam. | |
| 0.05 mMoves no measurement | Interpolated | Thickness of a floor board. | |
| 0.06 mMoves no measurement | Interpolated | Thickness of a wall board. | |
| 0.12 mMoves no measurement | Interpolated | How far the wall stands inside the edge of the floor, so the edge of each storey reads as a line. | |
| 0.45Moves no measurement | Interpolated | Width of the projecting room at the top against the topmost floor. | |
| 1.90 mMoves no measurement | Interpolated | Height of the projecting room at the top. | |
| 2.90 mIf 20% out: 0.58 m | Interpolated | Rise of the ridge above the topmost wall. | |
| 0.40Moves no measurement | Interpolated | Length of the ridge against the length of the topmost floor. | |
| 0.85 mMoves no measurement | Interpolated | Overhang of the shingle roof past the topmost floor — the widest projection in a building every storey of which already projects. | |
| 0.09 mMoves no measurement | Interpolated | Thickness of the shingle covering. | |
| 26.00 mMoves no measurement | Interpolated | Distance of the fortress wall from the house. This is the only building in the collection standing inside a fortification, and the wall is part of the site rather than scenery. | |
| 2.60 mMoves no measurement | Interpolated | Height of the coral-stone fortress wall. | |
| 0.30Moves no measurement | Interpolated | Depth of the tested joint engagement, as a share of the smaller member. | |
| 1Moves no measurement | Canon | Every storey projects past the one below it on all four sides, so the largest floor in this building is its highest and the smallest is the one standing on the ground. No other building here has a floor larger than the one under it — several have roofs that oversail, which is a different thing — and not one pack ever stated that as a rule. This one states the opposite. | |
| 4Moves no measurement | Canon | The projection of each storey is carried on pale arms, and how many there are is the household’s standing: four is the highest, three the next, and a house entitled to none does not project at all. So on this building rank decides how far you may build outward — the only pack here whose social rule sets a cantilever. | |
| 0Moves no measurement | Canon | Zero iron. The whole frame is pegged and wedged. The rumoh Aceh uses no iron either, and the two are worth reading together: there the absence answers ground that moves, here it answers a building that has to be able to work a little while leaning out. | |
| 1Moves no measurement | Canon | Who may be on which storey is fixed, and the top is the sultan’s own. The rule is declared and not checked: a floor forbidden to somebody looks exactly like a floor that is not — the same reason the Baduy pack gives for its unprovable prohibitions. |

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.
- 2.16 m
- 1.92 m
- 0.66 m
- 0.58 m
- 0.39 m
- 0.06 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 mid-plane, z = 0 — including every projection, which reaches equally on all four sides
536 points; largest mirror deviation 0.00 mm.
- passEvery tenon contained in its mortise
11 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
66 parts, every one bearing on something already standing or on the ground.
- passMesh integrity: indices, triangles, normals
6 triangles; indices in range, none degenerate, every normal unit length.
- passEvery storey is wider than the one below it
From 9.60 m on the ground to 12.90 m at the top, 1.34 times over. The largest floor in this building is its highest. No other building here has floors that grow as they rise, and not one of them ever stated that as a rule.
- passNothing projects further than the arm carrying it can reach
Each storey projects 0.55 m past the one below, so the topmost floor stands 1.65 m outside the frame against an arm reaching 1.95 m — 4 arms to a side. What sets the projection is rank; what sets the reach is carpentry; and nothing relates the two.
- passThe arms are as many as the rank allows, and they actually carry
24 arms on 3 projecting storeys, 4 to a side. The Bugis saoraja’s timpa laja also states rank and carries nothing, so it can lie; these hold the building up, so a claimed standing has to actually be built.
- passEvery part declares the dimensions it came from
66 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 66 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.
Reaching further out is the point of this building, and adding to it breaks nothing else: every storey is still wider than the one below, the arms are still there in the number the rank allows, the frame is still plumb, the roof still covers. What runs out is the arm. Every projection accumulates from the same frame, so the topmost floor is always the furthest out and the topmost arm always the longest — and past a point it is longer than a piece of timber leaning out of a post can be. The limit lands at the top, which is the storey that matters most.
The house as built
Rear prow raised to 0.67 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.
