Less is nothing

There is a particular kind of space that photographs beautifully and feels strangely empty when you enter it.

White walls. Perfect proportions. Almost no objects. Nothing seems out of place because almost nothing has been allowed to exist.

We have become very good at associating this absence with sophistication.

Digital products have their own version of it. The interface with generous whitespace, three words where there used to be ten, barely visible navigation and almost no friction that has not been intentionally removed. We call it clean. We call it intuitive. Sometimes we even call it human.

But reducing something is not the same as understanding what matters.

And usefulness is not the same as experience.

I started thinking about this again through Adolf Loos and Alvar Aalto, two architects associated, in very different ways, with the modern project of stripping away what architecture did not need.

What interests me is not whether one was right and the other wrong. It is what happened once modernism had removed so much that the question inevitably changed.

Once ornament disappears, what is left to make something meaningful?

What remains when ornament disappears

Adolf Loos's Ornament and Crime is often reduced to a slogan: ornament is unnecessary, therefore modernity should eliminate it.

His argument was more provocative than that. Loos saw excessive ornament as labour, material and cultural energy invested in surfaces that would become obsolete faster because fashion would move on. Removing ornament therefore carried an intellectual position about modern life, not simply a preference for empty walls.

That distinction interests me.

Because minimalism can very easily become another ornament.

We remove until the absence itself becomes a style. White space becomes a sign of taste. Simplicity becomes visual language. The lack of decoration starts decorating.

And then “less” stops being a consequence of thinking and becomes an aesthetic applied afterwards.

This happens constantly in digital design. We take things away because simplicity has become synonymous with good design, even when some of those things carried orientation, personality, reassurance or meaning.

The result can be impeccably usable and somehow completely forgettable.

Less is useful only when what remains matters. Otherwise, less is simply less.

Or perhaps less is nothing.

Aalto and the things a floor plan cannot show

Alvar Aalto took modernism somewhere else.

He did not reject function. His buildings had to work. But he seemed unwilling to accept that technical correctness was enough to describe what working meant.

Light mattered. The temperature of a material mattered. Acoustics mattered. The relationship between the hand and a door handle mattered. The way somebody lying in a hospital bed experienced the ceiling mattered.

At Paimio Sanatorium, the patient was not an abstract unit moving efficiently through architecture. The fact that a person would spend hours lying down changed the perspective from which the room had to be designed.

At Viipuri Library, acoustics and light were not decorative layers added after the building had been resolved. They were part of the architecture itself.

This is where I find Aalto extraordinarily contemporary.

He understood something we still struggle with in digital products: function is experienced through a body.

A space can fulfil every requirement in the brief and still feel hostile. A chair can support the body and still be unpleasant to sit in. A room can contain exactly the right amount of light and still make us want to leave.

Utility can be measured.

Experience has to be lived.

From utilitas to delight

Design has spent centuries negotiating this tension.

Vitruvius gave architecture three familiar obligations: firmitas, utilitas and venustas — strength, utility and beauty. We have translated and reinterpreted those words many times, but the tension remains surprisingly intact.

A thing has to work.

But at some point we also expect something to happen to us while we use it.

The interesting part is that delight does not necessarily mean decoration.

It can be the sound a heavy door makes when it closes. The way natural light moves across a wall during the afternoon. The slightly rough texture of a material under the hand. The acoustics of a room that allow a conversation to feel private without feeling isolated.

These things do not sit on top of utility.

They change the way utility is perceived.

And perhaps that is why the old opposition between functional and emotional design has always felt slightly artificial to me. We do not experience function separately from everything else. The physical sensation of using something changes our understanding of how well it works.

Interfaces escaped the screen a long time ago

The word interface still makes us think of screens.

Buttons, menus, forms, navigation.

But a door is an interface.

A hotel lobby is an interface.

So is the lighting inside a fitting room, the sound of a payment being accepted or the distance between a reception desk and the person who enters a building.

An interface is simply the place where we encounter a system.

Once you look at it that way, physical spaces become full of interaction design.

A hospital communicates before anyone speaks to you. A store teaches you where to go through light, materials, sound, smell and spatial hierarchy. An airport manages enormous flows of people partly through signs, but also through architecture. A restaurant can tell you whether it expects you to stay for twenty minutes or three hours before you even sit down.

None of this requires a display.

The space itself is the interface.

And physical interfaces have something digital design has spent years trying to recover: they are inherently multisensory.

You do not enter a building with your eyes alone.

The senses we barely design for

Digital design has been overwhelmingly visual for understandable reasons. Screens privileged sight, so our discipline became exceptionally sophisticated at organising pixels.

But sight is only one way of understanding where we are.

Sound tells us whether something happened without requiring us to look. Texture tells us what can be touched and how. Temperature changes whether a space feels inviting. Smell can create recognition faster than almost any visual identity.

Even silence can be designed.

Aalto understood that acoustic experience changes architecture because sound changes how we perceive distance, privacy, scale and material. A large space that absorbs sound feels different from one that throws every footstep back at us. Two rooms with identical dimensions can produce completely different experiences simply because of how they sound.

The same happens in interfaces.

Think about the tiny sound confirming that a payment succeeded. The vibration that tells you an action happened while the phone is still in your pocket. The resistance of a physical control. The click of a switch.

These are not embellishments around interaction.

They are interaction.

And as interfaces increasingly leave the screen — cars, wearables, retail environments, mixed reality, connected homes — we may need to become much better at thinking beyond what something looks like.

Immersion is not about adding more

There is a temptation to hear “multisensory” and imagine spectacle.

More sound. More animation. More haptics. More everything.

I think the lesson from Aalto is almost the opposite.

Sensory richness does not require sensory overload.

A material can be enough.

A small change in light can be enough.

A room becoming quieter at exactly the right moment can be enough.

This is perhaps where Loos and Aalto become unexpectedly useful together.

Loos reminds us to distrust things that exist only to decorate themselves. Aalto reminds us that removing decoration does not remove human perception.

Between those two ideas there is a much more interesting definition of simplicity.

Not an absence of things.

An absence of things without purpose.

And purpose can include much more than efficiency.

The physical world has always known this

We often speak about digital products becoming more immersive as though immersion were a technological invention.

Physical space has always been immersive.

You cannot scroll past architecture while you are standing inside it. You cannot mute the acoustics of a room or disable its temperature. Light reaches you whether you consciously notice it or not. Materials meet your body. Distance changes your behaviour.

The best physical environments do not demand that we analyse these decisions. We simply experience their consequences.

Perhaps digital design is slowly arriving at the same place.

As interfaces become less confined to rectangles of glass, we will have to design not only what people see and understand, but what they hear, touch, sense and inhabit.

And that changes the question.

It is no longer simply:

Is this useful?

It becomes:

What does it feel like for a human being to use it?

Aalto never needed to choose between modernism and warmth, between function and sensation, because for him those things could belong to the same system.

Maybe our interfaces should too.

We have spent a long time learning how to remove.

The more interesting challenge now might be knowing what deserves to remain — and what deserves to be felt.
