La sección como relato — the section as story — is the idea that cutting a building vertically reveals more about how it works than any other drawing. The plan organizes rooms. The section reveals experience.
What the Plan Cannot Tell You
A floor plan answers: how big is this room, how do I get from here to there, where are the walls? These are essential questions. A plan is the organizing document of a building.
But a plan cannot tell you:
- How tall the ceiling is and how it changes across the room
- Where natural light enters and at what angle in the afternoon
- Whether you pass through a low, compressed space before entering a high volume
- How the mezzanine relates to the ground floor below it
- What you see when you look up at the roof structure
All of these are section questions.
Reading a Section: Three Registers
A section cut through a residential building contains three registers of information:
The structural register: where columns and walls are, how beams transfer loads, what spans are possible. This is where the engineer reads the section.
The spatial register: how volumes stack and connect, where compression gives way to release, what the sequence of experience is as you move through the building. This is where the architect reads the section.
The light register: where glazing sits in relation to ceilings and overhangs, how far direct sun penetrates into the plan, where shadows fall at different hours. This is where the climate response is visible.
A good section is legible in all three registers simultaneously.
The Sequence of Compression and Release
The most powerful spatial experience in a building is not a uniformly generous ceiling height — it is the variation. A low entry that opens into a double-height living room. A corridor at 2.3 meters that arrives at a study with a 4-meter ceiling and a clerestory.
In MÉTODO, we compose the section the way a writer composes a paragraph: each spatial event has a function in the sequence. The compressed zone creates anticipation. The release creates arrival. The moment of light from above marks a place worth remembering.
This is what we mean by the section as story: it has a structure, a sequence, a beginning and an end. Walking through the building is reading the section in time.
How the Section Drives Material Decisions
The section also determines where materials appear. A concrete ceiling at 3 meters behaves differently than a concrete ceiling at 6 meters — the scale changes the weight of the material. Stone on a floor at the compressed entry feels anchoring. Stone on the walls of a double-height space would feel oppressive.
Materialidad honesta is a section-level decision as much as a surface decision. The material must be honest about its structural role, and the section reveals that role.
The Section in Construction Documents
When the building is being built, the section is the drawing the contractor refers to for height dimensions, floor-to-floor clearances, and the placement of every horizontal element. A section that is internally inconsistent — ceiling height that conflicts between one drawing and another — produces construction errors.
The completeness of the section in construction documents is a measure of design rigor. In MÉTODO, we do not release a construction document set without checking every section cut against every plan and every elevation for consistency.

The next time you look at a building you admire, find a section drawing of it. The section will tell you why it feels the way it does more clearly than any photograph.
When working with an architect, ask to see section studies early in schematic design. That is when the spatial logic is being set, and the section is where it is most visible.
