The Body Is Architecture

Humans and buildings are more alike than we think.

I continue to be fascinated by the human body — not just its form, but the way it functions too. The way parts connect, interlock, interact. In architecture and interior design programs, one of the fundamental representational elements you learn is the section cut — referring to the cut that runs through the body of a building, perpendicular to the horizontal plane. It reveals the innards of a building, vertically. You can also make a cut that is parallel to the horizontal plane — as if you were cutting a cake in half to make two layers — but this typically refers to the plan drawing.

The section cut is absolutely essential to understanding the way a building is designed, but also to the actual design itself. Architects and interior designers use this perspective in the process of creation to understand how the elements of a building or interior interact and get superimposed. It offers the three dimensionality that a plan cannot, while retaining the holistic view and measured precision that a perspective drawing lacks.

The section is also unique in that it highlights the relationship between exterior and interior. It calls attention to the physical boundary that separates the two, which then also serves to underlie the fine conceptual line between architecture and interior design. How is the facade of a building expressed interiorly? How may the inside impact the design of the outside? A section drawing will help you figure this out.


A pencil drawing of a section cut for a piece of furniture I imagined, with two bodies sitting on it.

Thus, cutting through a building or interior as you would, for instance, cut through a sandwich to reveal its layers, is not only supremely satisfying, it is a foundational element in understanding the practice designing space. One of my past teachers used to always encourage us to make cuts; when in doubt just cut through it. It will help reveal details you may have overlooked, and it will help guide the design.

In fact, you can cut a section through pretty much anything — not literally, of course, but on paper. In real life, we do it pretty frequently — for those of us who cook at least: chopping produce, slicing a cake, cutting bread, the aforementioned sandwich, …. Sections are, in the end, part of lives.

The naked body of a woman is curved revealing the architecture of her spinal bones.

Buildings and People Are Both Architectures

To extend the metaphor further, you can think of when scientists used to cut human bodies open to study their insides, to understand how the human body functions (and fails). Cutting open a building, then, is like cutting open a body. A body of architecture made of mortar, bricks, and stones versus a body of architecture made of tissue, muscle, and bone.

Hence, the connection: the body is architecture — or an architecture. It is a structure defined by a system, just as a building is. It is the product of design, even if that design is completely organic. It can be modified, or otherwise impacted, intentionally, or not.

It records the passing of time in the way it morphs physically and emotionally. Wrinkles — cracks on the ceiling; grey hair — paint chipping away; bones growing weaker — structural beams losing their strength. It’s all connected. The body, the building. The individual, the society.

“This brings us back to Semper’s privileging of the joint as the primordial tectonic element, as the fundamental nexus around which building comes into being, that is to say, comes to be articulated as a presence in itself. There is a spiritual value residing in the ‘thingness’ of the constructed object, so much so that the generic joint becomes a point of ontological condensation rather than a mere connection.” — Kenneth Frampton

His emphasis on the joint as the most essential element of architecture, points to the connection between the body and the building, since joints exist in the human form too. Frampton goes further into this analysis by foregrounding the inherent spirituality of the joint. The building thus becomes more than just a body; it becomes a person — much like when a body is linked to a mind and a soul, it becomes human.
