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. 1bayDepth1.44 mlength of the house
2. 2halfWidth1.44 mwidth of the house
3. 3tinggiRise0.92 mheight of the core ridge
4. 4paduDepth0.64 mlength of the house
5. 5eaveY0.62 mheight of the core ridge
6. 6surambiDepth0.60 mlength of the house
7. 7pelatarDepth0.52 mlength of the house
8. 8floorHeight0.36 mheight of the core floor

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 Symmetric across the entry axis — the one that does not carry the sequence

  4080 points; largest mirror deviation 0.00 mm.

• pass
  Every tenon contained in its mortise

  43 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

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

• pass
  Mesh integrity: indices, triangles, normals

  1536 triangles; indices in range, none degenerate, every normal unit length.

• pass
  Four roofed segments, in order, meeting end to end along one ridge

  Pelatar (sengkuap) → Surambi (sengkuap) → Palidangan (tinggi) → Padu (sengkuap), at 3 distinct ridge heights. The other thirteen buildings in this project have one roof over the whole plan; this one is read by walking the ridge and naming what changes overhead.

• pass
  The middle segment rises above both, and its form is the house’s name

  Bubungan tinggi: a tinggi over the core, 3.80 m above its neighbours. This is not a claim about structure — if the middle did not rise, the sequence would not read and a house called bubungan tinggi would have no high ridge. What is tested is whether this building’s name is true of it.

• pass
  The type rule selects a form rather than a number

  Bubungan tinggi → tinggi. The only rule in this project that selects a geometric primitive: elsewhere a rule picks a value and geometry follows it, here it picks the shape itself — and the house is named for that choice.

• pass
  The floors step down toward the front, and it is not a staircase of rank

  From 2.00 m at the core down to 1.40 m at the platform. The Palembang rumah limas also steps its floor and means the opposite by it: there where a guest sits is their standing, here the steps follow the sequence of roofs and the water that has to run away from a house standing on a tidal swamp.

• pass
  The anjung stand on either side of the core, or not at all

  Two wings, each projecting 2.20 m from the body, with their own roofs lower than the core’s.

• pass
  Shingle courses lap with no bare band, on every segment

  32 courses on each of 4 segments. Split shingles need a greater lap than a thatched roof, because what leaks is the joint.

• pass
  Every part declares the dimensions it came from

  318 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 318 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.

Bring the core ridge down and nothing fails: the chain still meets end to end, every segment still has its own roof, the shingles still lap, the floors still step. The only thing that stops being true is that the middle rises above its neighbours — and a building called “bubungan tinggi” whose ridge is not high is one whose name describes something that is not there. Fourteen buildings, fourteen rules that cannot be carried out, and only this one fails at its name: the others end with a building that cannot be constructed, or one that is dead, or one that has stopped being what it was for. This one ends with a building that is perfectly fine and is called something else.

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.
