Why Joseon Cracked Down on Silk Wallpaper and Layered Changho

Today, if you have the money, you can decorate a house however you like. Silk wallpaper out of an interior magazine, imported double-glazed windows. Nobody says a word.

In Joseon, that could get your house torn down. The Saheonbu, the inspection bureau of the day, could order it demolished or seized.

This piece is about that control. Three things were at the center of it: silk wallpaper, silk-gauze changho, and layered changho.

1. Worse Than Extravagance: Chamnam

Joseon didn't regulate interiors this closely to make people save money.

The state ideology was Neo-Confucianism, and rank was meant to be visible in buildings. The rules were there to keep that order in place.

The key word is chamnam (僭濫).

Chamnam means stepping beyond your own rank to copy the forms reserved for those above you.

A commoner living like royalty wasn't a matter of taste. It was a threat to the order.

The penalty was real. King Seongjong ordered the Saheonbu: "Anyone who has built a house beyond the legal standard since the law was established is to be charged, and all such houses are to be torn down."

2. What the Enforcers Looked For

The housing rules, gasa-jehan, covered more than size. They reached into the decoration inside and the shape of the door panels.

① Silk wallpaper and silk changho (neungna, sachang)

An ordinary house papered its changho with hanji.

Wealthy households used silk instead, on the walls and on the changho. Sachang was one such fabric. Neungna, the finest silk, was another.

These cost far more than hanji. That made them an easy target.

② Layered changho and dense lattice

Several changho hung one behind another, or sets changed out by season, meant great wealth.

Jangmilmun, doors with tight, elaborately carved lattice, took so much material and labor that only the palace and the royal family could have them.

3. Standards Set by Law, by Rank

The rule starts with a royal instruction King Sejong gave the Ministry of Rites in the first month of his 13th year (1431). It had two layers.

Room count followed rank. 60 kan (a kan is the bay between two pillars, the basic unit of a Korean house) for a daegun, a king's son by the queen. 50 kan for the king's own sons and brothers, and for princesses. 40 kan for officials of the 2nd rank or above. 30 kan for the 3rd rank and below. 10 kan for commoners.

Decoration was banned outside the royal family. No dressed stone beyond the foundation stones. No carved boa-ji brackets. No polychrome or dancheong paintwork.

Higher rank did not mean a bigger allowance here. Even a noble with a 40-kan house could not paint it in dancheong. Outside the palace walls, that visual language belonged to royalty alone.

The ranks were spelled out in more detail in the revision of Sejong's 22nd year (1440). Again, what separated them was size, not ornament.

Inside a daegun's 60 kan, the pavilion could take 10 kan. Princesses and the king's brothers got 8, officials of the 2nd rank and above 6, commoners 3.

Pillar height stepped down too: 13 cheok for princesses and above, 12 for officials, 7 for commoners. They were all houses, but they did not stand at the same height.

There was one exception. Shrines, and houses inherited from parents or bought outright, were exempt. The law left ancestral rites alone, and it did not tear down property that already existed.

So a changho in Joseon was not just interior decoration. It was a way of showing, on the face of the house, who lived there.

Was the rule kept for all five hundred years? Seongjong had to order houses torn down. That is already half the answer.

No. 2, "The Era's Desire, Held in a Single Door," is about the people who tried to buy their way past this line.
