In fire cause investigation, the fuel load rarely matches the architectural plan. The plan says the office is for paper. The office contains ten gallons of cleaning fluid. The fire burns the fluid. The fire ignores the plan. A building code is a set of rules. The code assumes a world of right angles. The code assumes humans follow instructions.
The fire follows physics. Physics does not care about the building code. Physics finds the gap where a plumber ran a pipe through a fire wall. Physics finds the one door left open by a tired clerk. The fire moves through the gap. The fire grows. I look at the ash. I look at the plan. The plan is a lie.
The Furniture Business vs. Reality
I see the same lie in the furniture business. Most people use a template. The template is a box. The box has four sides. The box has four 90-degree corners. The world is not a box. Hong Kong is not a box. Hong Kong is a city built on hills.
The buildings follow the hills. The rooms follow the buildings. The rooms have angles. The rooms have beams. The rooms have pillars. The template cannot see the pillar.

The Actual Reality
The software assumes a rectangle; the developer builds a diamond. This is where the error begins.
It is a Friday afternoon in Sha Tin. The air is humid. The flat is on the 22nd floor. The flat is small. The flat has a living room. The living room is a diamond shape. Developers like the diamond shape. The diamond shape creates more windows. More windows mean a higher price.
But the diamond shape has no rectangles. Every wall meets the next wall at an odd angle. The angle is not 90 degrees. The angle is 112 degrees. Or the angle is 68 degrees.
The estimator stands in the room. The estimator has a laser. The laser is red. The red dot hits the wall. The wall is white. The estimator looks at the software on the tablet. The software is a template. The software asks for the width. The software asks for the depth.
The software assumes the room is a rectangle. The estimator knows the room is not a rectangle. The estimator sees a beam. The beam is low. The beam runs across the ceiling. The beam is 300 millimeters deep.
The software does not have a button for the beam. The software does not have a box for the 112-degree angle. The estimator is in a hurry. The estimator has three more flats to see before dinner. The estimator enters the width. The estimator enters the depth. Then the estimator moves to the bottom of the screen.
There is a blank space. The space is for manual notes. The heading says “special”. The estimator writes two lines. She writes about the beam. She writes about the angle. This is the fourth time this week she has used the “special” heading.
This is where the system breaks. A template is a belief. The template encodes a belief about what is typical. The company believes the rectangle is typical. The company builds a system for the rectangle. The system is fast. The system is cheap. But the rectangle is not typical in Sha Tin. The rectangle is not typical in Ma On Shan.
The exception is the rule. When the exception is the rule, the template becomes the source of the error. The manual lines are the real work. But the manual lines are the least tested part of the system.
I had hiccups during a presentation once. I was talking to a group of architects. I was talking about flashover. A hiccup happened. The audience laughed. I waited. Another hiccup happened. My body had an error. The error was not in the plan. I had to finish the talk with the hiccups. Every sentence was broken. The template of my speech was gone. I had to manage the exception. The exception was the only thing the audience heard.
The Hubble Lesson
In , the Hubble Space Telescope went into orbit. The telescope was the most expensive eye in history. The heart of the telescope was a mirror. The mirror had to be perfect. The company made a template to test the mirror. The template was a tool called a reflective null corrector.
The tool used a lens and a cap. The cap had a hole. The hole was in the wrong place. A technician found a gap. The technician used a metal washer to fill the gap. The washer was a manual override. The washer was thick.
The template was the testing tool. The technician added a washer. The result was a “perfect error” launched into space.
The engineers saw the data. The data said the mirror was wrong. The data showed a massive error. But the engineers trusted the template. They thought the testing tool was the truth. They ignored the manual override. They launched the telescope. The telescope was blind.
The mirror was the wrong shape. The template had created a perfect error. The exception handler had become the main process. It failed because it was not designed to be the main process.
Hong Kong apartments are like the Hubble mirror. They are full of 1.3-millimeter errors. They are full of beams and pillars. If a company uses a rectangle template, they are guessing. They are using the “special” line to fix a broken system.
The “special” line goes to the factory. The factory worker is busy. The worker sees the rectangle on the drawing. The worker does not read the manual note at the bottom. The worker cuts the wood. The wood is a rectangle. The cabinet goes to Sha Tin. The cabinet hits the beam. The cabinet does not fit.
The worker tries to fix the cabinet in the flat. The worker uses a saw. The saw creates dust. The saw leaves a rough edge. The cabinet is now weak. The customer is unhappy. This happens because the system was designed for a rectangle that does not exist. The company runs most of its work through the back door of manual overrides.
I stopped trusting the rectangle. I look for the truth in the measurement. A good system does not have a “special” heading. A good system assumes every line is unique. This is why people look for professional 室內設計 when they have a difficult room.
They need a system that sees the 112-degree angle. They need a system that sees the beam as a fact, not an exception. Hohome has a history of fifty years. Fifty years is a long time. In fifty years, you see many rooms. You see that no two rooms are the same. You learn that the “special” case is the only case.
Material Integrity: Plywood vs MDF
The company uses plywood. Plywood is a good material. Plywood has layers. The layers make the wood strong. Plywood does not warp in the Hong Kong heat. Plywood is better than MDF. MDF is just dust and glue. If you cut MDF to fit a beam, the MDF falls apart. If you cut plywood, the plywood stays strong.
The company uses a 100% completion guarantee. This is important. A guarantee is a promise. In the furniture business, many projects do not finish. They do not finish because the template failed. The company finds a pillar. The company says the pillar is too difficult.
They ask for more money. They stop the work. The customer lives with a hole in the kitchen. A 100% completion guarantee means the company owns the error. If the measurement is wrong, the company fixes the measurement. They do not charge the customer for the “special” line.

Remains strong at any angle
The Reality of the Void
I investigated a fire in a renovation project once. The workers had used a template for the wiring. They followed the diagram. But the wall had a hidden void. The void was not on the plan. The workers ran the wire through the void.
The wire rubbed against a sharp metal stud. The insulation wore away. The spark hit the dust. The flat burned. The template killed the flat. The workers should have looked at the wall. They should have seen the void. They should have treated the void as the reality.
When you build furniture, you are building a map of the room. If the map is wrong, the furniture is wrong. A rectangle is a simple map. It is a map of a desert. Hong Kong is a jungle. You need a map that shows every tree. You need a map that shows every rock.
The laser measure is the tool for the map. But the human must use the laser. The human must measure the top of the wall. The human must measure the bottom of the wall. Walls are often slanted. A wall can be five millimeters wider at the top. Five millimeters is enough to stop a wardrobe.
Precision is not about being fancy. Precision is about avoiding the saw. If the furniture fits, the worker does not use the saw. If the worker does not use the saw, the edge is clean. If the edge is clean, the seal is tight.
A tight seal keeps the stickroaches out. It keeps the moisture out. It keeps the formaldehyde levels low. Hohome uses E0 plywood. E0 means the wood is safe. You do not want to breathe the gas from cheap glue. You especially do not want to breathe it when the worker has sawed the edges open to fit a beam.
The Truth in Measurement
I think about the estimator in Sha Tin. She is still there. She is looking at the chamfered corner. She is wondering if she should measure the angle. She decides to measure the angle. She puts down the tablet. She uses a protractor. She writes down the number. She deletes the “special” line.
She draws the actual shape of the room. This takes more time. It is harder work. But the drawing is now the truth. When the drawing is the truth, the factory can do its job. The CNC machine reads the drawing. The machine cuts the plywood at 112 degrees.
The parts go into a box. The box goes to Sha Tin. The installers carry the parts up the elevator. They put the cabinet against the wall. The cabinet slides into the corner. It fits. There is no gap. There is no dust. The customer smiles. The system worked because the system accepted the irregularity.
Systems fail when they try to force the world into a shape. The most reliable process is the one that handles the exception as the standard.
I see this in fire walls. I see this in insurance forms. I see this in furniture. The most reliable process is the one that handles the exception as the standard. If every room is irregular, then irregularity is the standard. You build the whole company around the irregularity.
You buy the machines that can cut any angle. You train the estimators to see the beams. You use the plywood that can handle the stress. I still have the hiccups sometimes. Not often. But when they happen, I stop talking. I do not try to talk over the hiccup. I accept the hiccup.
I wait for the body to return to its state. You cannot template a human body. You cannot template a Hong Kong flat. You can only measure what is there. You can only build for the truth. Anything else is just a manual override. And a manual override is just a mistake that has not happened yet.
I prefer the truth. The truth fits the first time. The truth does not require a saw.
That is the only way to build a home in this city. It is the only way to make sure the fire does not find a gap. It is the only way to sleep at night.
