Silas is a bicycle builder. Silas works in a small shed. Silas builds frames from steel tubes. Silas does not use a chart. Silas does not look at the height of the rider.

Silas measures the length of the femur. Silas measures the length of the torso. Silas measures the reach of the arms. Silas knows that two men of the same height have different legs. Silas knows that the seat must fit the bone.

The bone does not care about the average. The bone is a specific length. The bike must match the bone. Silas ignores the standard size. Silas builds the bike for one person.

The Failure of the Identical Bench

Sarah is a nurse. Sarah works in a hospital in the center of the city. Sarah has worked in the hospital for thirteen years. Sarah works in the recovery ward. Sarah sees the patients after surgery.

Sarah knows the bodies of the patients. The bodies are broken. The bodies are heavy. The bodies are stiff. Sarah wheels the patients to the courtyard. The courtyard is a space for fresh air. The courtyard has trees. The courtyard has many benches.

Sarah pushed Arthur into the courtyard. Arthur is seventy-four years old. Arthur had a surgery on his hip. Arthur wanted to sit on a bench. Sarah stopped the wheelchair. Sarah looked at the bench.

The bench was low. The seat of the bench was forty-two centimeters from the ground. Sarah knew the problem. Arthur cannot bend his hip that far. Arthur is tall. Arthur is stiff. Arthur cannot lower himself to a seat that is forty-two centimeters high. Sarah looked for a higher bench. Every bench in the courtyard was the same. Every bench was forty-two centimeters high.

The architect planned the courtyard. The architect looked at a book. The book had data. The data showed the average height of a human. The data showed the average length of a leg. The architect chose a bench for the average human.

The Average is a Ghost

The architect wanted the courtyard to look clean. The architect wanted the benches to match. The architect bought forty benches. The benches were identical. The benches were built for a person who does not exist.

The average is a ghost. The average is a number on a page. I have studied body language for a long time. I have watched how people sit. I have watched how people stand.

Ian D. says that posture is a map of the internal state. A person in pain does not sit like an average person. A person in pain needs support. A person in pain needs a specific angle. The average bench provides no support for the person in pain. The average bench is a wall.

Sarah tried to help Arthur. Sarah held the arm of Arthur. Arthur gripped the armrest of the wheelchair. Arthur tried to lower his body. Arthur stopped. The pain was in the hip. The bench was too far down.

Arthur could not reach the wood. Sarah felt the weight of Arthur. Sarah is strong. Sarah is not as strong as a falling man. Sarah pulled Arthur back into the wheelchair. Arthur was tired. Arthur was sad. Arthur did not get to sit on the bench. Sarah wheeled Arthur back to the ward.

The hospital has three hundred patients. No patient is average. Some patients are very tall. Some patients are very short. Some patients weigh one hundred and twenty kilograms. Some patients weigh forty-five kilograms. The hospital plan treats them as one number. The plan is efficient for the paper. The plan is a failure for the body.

The Architecture of Efficiency

I rehearsed a conversation with the hospital director. I stood in my kitchen. I spoke to the toaster. I told the director that the benches were a mistake. I told the director that the benches hurt the patients. I told the director that variety is a medical necessity. I did not go to the office. I did not speak to the director. I am a consultant. I am not a nurse. I only watch.

Urban planners follow a process. The process starts with a budget. The process moves to a catalog. The planner looks at the AGORA model. The planner looks at the AVENUE model. The planner looks at the price. The planner looks at the maintenance.

The planner wants the bench to last twenty years. The planner wants the bench to resist the rain. The planner orders one hundred benches of the same SKU. The SKU is a single size. The single size is easy to track. The single size is easy to install.

This is how the procurement works. A city council meets in a room. The room has no windows. The council looks at a map. The council marks the spots for the furniture. The council picks a color. The council picks a material.

The council never sits on the bench for one hour. The council never tries to stand up with a bad hip. The council buys the average. The average is a lie that makes the paperwork easy.

The Chair Dictates the Behavior

I made a mistake in my first year of coaching. I told a tall man to sit with his knees at a right angle. I told the man this was the power position. The man was two meters tall. The chair was for a smaller man. The man looked like a grasshopper.

The man was uncomfortable. The man could not focus on the speech. The man was fighting the chair. I learned that the chair dictates the behavior. If the chair is wrong, the person is wrong.

Hospitals need different heights. Hospitals need benches with arms. Arms help the patient stand. Arms help the patient sit. A bench without arms is a slide. A low bench is a trap. The BONN model has different versions. Some versions are longer. Some versions have different backs.

Sarah knows this truth. Sarah sees the truth in the joints of the patients. Sarah sees the truth in the sweat on the forehead of Arthur. Arthur is a person. Arthur is not a data point. The courtyard should serve Arthur. The courtyard was built for the average. The average did not show up today. Arthur showed up. Arthur went back to his room.

The Ends of the Curve

The Bell Curve is a shape. The middle of the curve is high. Most people are in the middle. The ends of the curve are thin. The ends are where the struggle lives. The ends are the people who are too tall or too weak.

We build the world for the middle. We leave the ends to struggle. In a hospital, everyone is at the end of the curve. No one in a hospital is at their peak. No one in a hospital is standard.

I watched a man try to use a park bench in Marseille. The man had a cane. The bench was a slab of stone. The stone was cold. The stone had no back. The man stood for five minutes. The man looked at the stone.

The man shook his head. The man walked away. The stone was a design choice. The stone was modern. The stone was average. The stone was useless.

A City of Ghosts

The design of public space is a moral choice. If you choose one size, you choose who belongs. If the bench is low, the elderly do not belong. If the bench is narrow, the heavy do not belong. We create a city of ghosts. We create a city where only the fit can sit.

“If the bench is low, the elderly do not belong. If the bench is narrow, the heavy do not belong. We create a city of ghosts.”

– Urban Design Ethos

The nurse knows this. The nurse carries the weight of the design. The nurse uses her own back to fix the mistake of the architect.

I look at the catalog from Bio Jardins. I see the models. I see the AGORA. I see the ATLANTIC. I see the CANVAS. These are tools. A tool must fit the hand. A bench must fit the hip.

The diversity of the models is the value. You do not buy a bench. You buy a seat for a person. If you buy ten benches, you should buy three types. You should provide for the distribution.

Sarah still works at the hospital. Sarah still wheels patients to the courtyard. Sarah brings a foam block now. Sarah puts the foam block on the bench. The foam block makes the bench higher. The foam block is ugly. The foam block is not in the plan. The foam block is the only thing that works. Sarah does the job of the architect. Sarah fixes the average with a piece of foam.

I stopped looking at the middle. I started looking at the person who cannot sit down. I started looking at the person who cannot get up. The plan is a map. The person is the territory. We should build for the territory.

We should build for Arthur. Arthur deserves a seat. Arthur is not a number. Arthur is a man who wants to see the trees. The trees do not care about the average. The trees are all different heights. The trees are the only thing in the courtyard that make sense.
