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.

The dimensions

DimensionValueClassWhat it means
yardWidth9.50 mIf 20% out: 46.36 mInterpolatedWidth of the tanean, from the row of houses to the row of kitchens. It is not space left over between buildings: it is the room, and its width is set by what is done on it — drying tobacco and rice, weddings and funerals, and receiving anybody who is not family.No source
housePitch7.40 mIf 20% out: 42.18 mInterpolatedDistance from one house to the next along the tanean. The length of the yard is this figure times the number of houses — so the length is a genealogy.No source
yardMargin2.20 mIf 20% out: 4.18 mInterpolatedThe stretch of tanean left at the east end, where the next house will stand.No source
yardThickness0.08 mMoves no measurementInterpolatedThickness of the beaten earth levelled into the tanean.No source
houseWidth5.60 mIf 20% out: 1.12 mInterpolatedFrontage of a married daughter’s house, facing the tanean.No source
tonghuhWidth6.80 mIf 20% out: 1.36 mInterpolatedFrontage of the parent household’s house. This figure and the daughters’ frontage are independent, and the order between them is what is guarded: a daughter’s house grown past the tonghuh makes the row say something it must not.No source
houseDepth6.20 mMoves no measurementInterpolatedDepth of a house, front to back.No source
plinthHeight0.45 mIf 20% out: 0.09 mInterpolatedHeight of the brick plinth above the tanean. A Madurese house is not raised on posts: its floor is a low masonry platform, and the difference from a stilt house is an order of magnitude.No source
wallHeight2.35 mIf 20% out: 0.47 mInterpolatedHeight of the board walls to the plate.No source
wallThickness0.07 mMoves no measurementInterpolatedThickness of a wall board.No source
doorWidth1.05 mMoves no measurementInterpolatedWidth of the door, which always faces the tanean.No source
postSection0.15 mMoves no measurementInterpolatedSection of a timber post.No source
umpakSocket0.04 mMoves no measurementInterpolatedDepth of the shallow socket in the pad stone the foot of a post sits in. Without it a post only touches its stone on one plane, and a joint whose two members do not enter each other holds nothing.No source
umpakHeight0.22 mMoves no measurementInterpolatedHeight of the stone pad under a post.No source
trompesanRise1.55 mIf 20% out: 0.31 mInterpolatedRise of a trompesan roof above the wall: the lowest, nearly a pyramid, and the one most often standing.No source
pacenanRise2.15 mMoves no measurementInterpolatedRise of a pacenan roof: a gable, steeper, its ridge as long as the house.No source
bangsalRise2.60 mMoves no measurementInterpolatedRise of a bangsal roof: the tallest, and the house that carries one says the most about its household.No source
ridgeShare0.45Moves no measurementInterpolatedLength of a hipped roof’s ridge against the length of the house under it.No source

yardIsTheRoom1Moves no measurementCanonThe tanean is the room, not the space left between buildings. Everything a household does except sleep is done on it, and the buildings are arranged around it. So the yard is in the part list, and it is made before anything that stands around it.Tulistyantoro, L., “Makna Ruang pada Tanean Lanjang di Madura”, Dimensi Interior 3(2), 2005.
seniorityRunsEast1Moves no measurementCanonThe parent household stands at the west end of the row, and each married daughter’s house is added eastward in the order she was born. Standing here is a position — as in the Karo siwaluh jabu, except that there the positions are eight places in one room and here they are eight separate buildings.Wiryoprawiro, Z. M., Arsitektur Tradisional Madura Sumenep dengan Pendekatan Historis dan Deskriptif (Laboratorium Arsitektur Tradisional, FTSP ITS, Surabaya, 1986).
langgarClosesTheWest1Moves no measurementCanonThe langgar stands at the west end of the tanean, because prayer is toward the west. It is the second rule in this project to come from outside the archipelago: the rumoh Aceh lies east–west for the same reason. The note in the Aceh pack calling it the only one is now wrong, and what survives is the narrower claim — there a whole house plan is turned by it, here one small building in an arrangement.Tulistyantoro, L., “Makna Ruang pada Tanean Lanjang di Madura”, Dimensi Interior 3(2), 2005.
housesAreAlike1Moves no measurementCanonThe houses of one tanean are the same house repeated, with the parent household’s larger. So the roof rule here applies to a set of buildings at once — the only rule in this project that does.Arsitektur Tradisional Daerah Jawa Timur (Departemen Pendidikan dan Kebudayaan, Jakarta, 1986).

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. 1yardWidth46.36 marea of the yard
  2. 2housePitch42.18 marea of the yard
  3. 3yardMargin4.18 marea of the yard
  4. 4tonghuhWidth1.36 mhow much wider the tonghuh is
  5. 5houseWidth1.12 mhow much wider the tonghuh is
  6. 6langgarSetback0.52 msetback of the langgar
  7. 7wallHeight0.47 mheight of a house ridge
  8. 8langgarSide0.44 msetback of the langgar

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
    Every tenon contained in its mortise

    21 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

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

  • pass
    Mesh integrity: indices, triangles, normals

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

  • pass
    The yard is empty, and the yard is the room

    232 m² of beaten earth with nothing on it. It is not space left between buildings: the buildings are arranged around it, and nearly everything a household does is done on it.

  • pass
    Seniority runs from the west, and no daughter’s house outgrows the tonghuh

    3 houses, a 6.80 m tonghuh at the west end and 5.60 m daughters’ houses following eastward in order of birth. The positions cannot go wrong by themselves; the sizes can, because those two frontages are independent numbers.

  • pass
    The langgar closes the west end, and nothing stands west of it

    The langgar stands 2.6 m west of the tonghuh, because prayer is toward the west. It is the second rule in this project to come from outside the archipelago; the first is the rumoh Aceh, and there what is turned is a whole house plan.

  • pass
    The row is regular, and it lengthens only at the east end

    The pitch stays 7.40 m, and adding a household moves none of the houses already standing: what grows is the yard at the east end. No symmetry is claimed along the tanean, because a row grown from one end is not symmetric — the second time in this project, after the betang.

  • pass
    Every part declares the dimensions it came from

    74 parts, every one tagged. By least-sourced input: 0 measured, 0 canon, 74 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.

Every daughter builds the same house, so widening it widens all of them at once — and not one part of the arrangement becomes wrong: the langgar still closes the west end, the yard is still clear, the row still runs in birth order, the pitch still holds. What happens is that the daughters’ houses grow past the tonghuh, and the row then says something it must not. It is the second refutation in this project that ends with a perfectly sound building, after the Balinese bale: nothing would fall down, the arrangement would simply be wrong about the family living in it.

The house as built

pass6.80 m / 5.60 mthe tonghuh · a daughter’s house

3 houses, a 6.80 m tonghuh at the west end and 5.60 m daughters’ houses following eastward in order of birth. The positions cannot go wrong by themselves; the sizes can, because those two frontages are independent numbers.

Rear prow raised to 7.22 m

fail6.80 m / 7.22 mthe tonghuh · a daughter’s house

house 2 is wider than the tonghuh; house 3 is wider than the tonghuh

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.
