The Architectural Reasons Why Your Childhood Home Feels 'Strangely Comforting'—The Relationship Between Memory and Space
Introduction: The Moment You Open the Front Door of Your Childhood Home
Have you ever felt the tension leave your entire body the moment you opened the front door after returning to your childhood home for the first time in a while?
You take off your shoes, walk down the hallway, and enter the living room. You haven't done anything particularly unusual. Yet, even though you've simply 'come home,' there is a deep sense of relief that is clearly different from when you return to the apartment where you live alone.
It's easy to just say, 'Well, it's your childhood home, so of course it's comforting.' But as an architect, I want to dig a little deeper.
The true nature of that sense of relief isn't just because your family is there. Even if you return to an empty childhood home, that feeling is still there. This means the building itself must be speaking to your body in some way.
Today, I will try to put into words, from an architectural perspective, that feeling of 'my childhood home is comforting'—a sensation everyone knows but no one has ever thought to explain.
There are 'dimensions' your body remembers
When you return to your childhood home, you can go to the bathroom in the dark. You can reach the doorknob even with your eyes closed. You don't have to count the stairs, yet your feet stop at the very last step.
This is less about memory and more about the dimensions of space carved into your body.
The human body remembers the dimensions of the space it has spent many years in with surprising precision. The height of the ceiling, the width of the hallway, the position of the doors, the height from the floor to the window. You have never been conscious of them, but your body knows them all.
In the world of architecture, there is a term called 'human scale.' It refers to the dimensions of a space based on the size of the human body. Your childhood home is the 'origin' space where your body learned the human scale as you grew up from childhood.
Do you remember feeling somewhat uneasy when you first moved into your own place? It was because your body hadn't yet adjusted to the size of the room or the placement of the furniture. After a few months, you stopped noticing it. That was because your body had learned the new dimensions.
When you return to your childhood home and your tension instantly melts away, it is because your body is reuniting with the 'dimensions it spent the longest time learning.' Your body decides, 'This is a place I know; it is safe,' before your conscious mind does. That relief is a memory held in your bones and muscles.
'Scent' triggers memories of space
The scent of your childhood home. It might be the smell of wood, or perhaps the smell of tatami mats. The smell of detergent, the smell of cooking, the smell of incense. That 'certain scent' unique to every house that is hard to put into words.
It is said that the sense of smell is more directly linked to memory than any of the other five senses. Scent information travels directly to the hippocampus and amygdala, which govern memory and emotion in the cerebrum. It connects directly to memory and emotion without going through rational processing like sight or hearing. This is called the 'Proust effect.'
The reason you feel relief the moment you open the door to your childhood home is that the scent is pulling the trigger on your memories. The moment you smell it, thousands of days of memories spent in that space are called up all at once. Before your consciousness recognizes it as 'my childhood home,' your body has already reacted with 'I'm home.'
In an article about libraries, I mentioned that the smell of books and wood creates an 'intellectual and calm atmosphere.' The scent of a childhood home is more personal and more powerful. It is because it is a one-of-a-kind atmosphere in the world, created by the scent of building materials mixed with the scent of the life lived there over decades.
When architects design a space, they sometimes even consider the scent of the materials. But the scent of a childhood home cannot be designed. It is an architectural element that only time and living can create.
There is a 'timetable' in the light from the window
Try to remember the light that enters through the windows of your childhood home.
The dazzling light streaming in from the east window in the morning. The gentle patch of sunlight falling on the living room floor at noon. The wall dyed orange by the setting sun in the evening.
Even in the same room, the color and direction of the light change completely depending on the time of day. And your body remembers the patterns of those changes.
You can tell roughly what time it is by the angle of the morning light. You can tell the season by the color of the afternoon light. The light in your childhood home has a 'timetable,' and you used it as part of your internal clock.
In a room where you live alone, this timetable is reset. The orientation of the windows, the relationship with surrounding buildings, the depth of the room—everything is different, so the light's timetable changes too. The reason it takes time to get used to a new room is partly because your body is relearning this light timetable.
When you return to your childhood home, that light timetable remains exactly as it was. The color of the light in the living room at 3:00 PM is the same as it was when you were a child. That consistency creates a deep sense of security.
In an article about art museums, I mentioned that 'museum lighting is the ultimate stagehand,' but the light in your childhood home is not a stagehand—it is the protagonist. Many of your family memories are suspended within specific light. The light from the pendant lamp illuminating the dinner table. The light leaking through the gap in the curtains in the morning. It is light created by architecture and given meaning by time.
The 'Soundscape' is Different for Every House
Close your eyes and try to remember the sounds of your childhood home.
The ticking of the clock. The hum of the refrigerator motor. The sound of the wind rattling the window. The sound of family members walking upstairs. The faint sound of the television from the next room. The sound of a distant railroad crossing.
Even if you don't remember these sounds one by one, the totality of them—the 'soundscape' of your childhood home—is etched into the deepest parts of your body.
Depending on the structure and materials of the architecture, the way sound resonates is completely different for every house. In a wooden house, the floor creaks slightly when someone walks on it. The quality of that sound differs from house to house based on the age of the building, the type of wood, and the structure under the floor. In a reinforced concrete house, while outside noise is blocked, indoor sounds resonate a bit more. That, too, is a sound unique to that house.
In an article about train stations, I mentioned that 'you don't remember the sounds of your favorite stations, but you do remember unpleasant ones.' The sounds of your childhood home are the same. When you are there, the sounds of the house don't enter your consciousness. But the moment you return home and get into bed, you are enveloped by that soundscape and feel a sense of security for no reason at all.
That is because these are the sounds you heard on the nights you fell asleep thousands of times. Your body knows that 'it is safe to sleep amidst these sounds.' Being able to sleep at your childhood home isn't a matter of the bed or the futon; it's a matter of the soundscape.
Sometimes, a 'Stain on the Ceiling' is the Source of Comfort
Let me tell you something a little strange.
Isn't there a stain on the ceiling of your childhood home? Maybe the wallpaper seams are slightly misaligned, there's a scratch on a pillar, or the door handle is a little loose.
A space that is perfect, like a new model home, is not necessarily comfortable for humans. When surrounded by white walls without a single scratch, you feel a certain tension. That is because there is no sense of life there.
The 'imperfections' in your childhood home—scratches, dirt, signs of aging—are the accumulation of time itself. The scratch on the pillar from when you bumped into it as a child. The tatami mats that have changed color over the years. The slightly warped window frame. These are all proof that 'life has been lived in this house,' and they are the physical traces of your own life.
In the world of architecture, there is a philosophy that affirms aging as a 'wabi-sabi' aesthetic. But the reason the imperfections of a childhood home create a sense of security is not a matter of aesthetics; it is for a much simpler reason. Because a place with a scratch is a 'place I know.' Because things that aren't perfect are 'my place.'
In my article about hotels, I discussed how hotels are architecture designed to create an 'extraordinary' experience. A childhood home is the exact opposite; it is architecture where the 'accumulation of daily life' itself becomes the value of the space. Neither is superior to the other. However, I believe that for humans, a 'place to return to' requires a familiar imperfection more than it requires perfection.
The 'Floor Plan' Created the Distance Between Family Members
Try to recall the floor plan of your childhood home.
Were the living room and kitchen connected, or were they separate? When you went from your room to the living room, did you walk through a hallway? When you went to the bathroom, did you pass in front of someone else's room?
Floor plans physically dictate the frequency and quality of family communication.
In a floor plan where you have to pass through the living room to get to your own room, you see your family every time you come home. In a floor plan where you can go directly to your room from the entrance, you can enter your own world without seeing anyone. It is not a matter of which is good or bad; each floor plan created the sense of distance for that specific family.
The reason a childhood home's floor plan feels comforting is that this sense of distance has soaked into your body as something 'natural to you.' The physical distance from your family—that feeling of being neither too close nor too far—was determined by the floor plan.
When adults have their own homes, many unconsciously choose floor plans similar to their childhood homes. The size of the LDK, the distance to the bedroom, the location of the plumbing. Even if you cannot put it into words, you are trying to recreate the 'just right distance' that your body remembers.
A floor plan is not just an arrangement of rooms; it was a blueprint for family relationships. If you trace the reasons for the comfort of a childhood home, you might find that you end up at those walls and hallways that determined the distance between people.
Conclusion—Architecture Preserves Memory
In this series, I have talked about various architectural 'tricks.' The light in a cafe, the flow lines in a mall, the height of shelves in a convenience store. All of these were intentionally incorporated by the designers.
But today's story is a little different. The comfort of a childhood home was not intentionally designed by anyone. The time spent living there carved meaning into the space.
Your body remembers the dimensions. The scent evokes memories. The schedule of light regulates your internal clock. The soundscape allows for sleep. Imperfection creates peace of mind. The floor plan teaches the distance between family members.
Architecture is a vessel for memory. Invisible time is soaked into the walls, floors, and ceilings. The reason your childhood home feels 'somehow comforting' is that the building is your memory itself.
If you read this article and remembered your childhood home even a little bit.
Next time you go back, try pausing for just a moment before opening the front door. Place your hand on the doorknob and be conscious of the space you are about to reunite with.
The scent, the light, the sound, the temperature, the dimensions. Everything should be there to welcome you back.
That building remembers you more than you think.
