Notes on architecture & design

Structure is a decision, not an accident

Five notes on how material, light, and restraint shape the spaces we spend our lives in — for anyone who looks at buildings and wants to know why they work.

MaterialWhat a building is honest about
LightThe material no one budgets for
RestraintWhat good design leaves out
A minimalist concrete structure with clean geometric lines. Raw concrete, left to speak for itself.

01 — Material

Materials tell the truth, if left alone

A material that's painted, veneered, or clad can be made to look like almost anything. Left exposed, it can only look like what it is — concrete reads as concrete, timber as timber, and a building built this way is, in a small way, incapable of lying about what it's made from.

This is the whole argument behind exposing structure rather than hiding it: not an aesthetic preference for gray, but a belief that a material shown plainly earns more trust than one dressed up to resemble something else.

02 — Light

Light is a material too

A floor plan describes where the walls go, but not what a room feels like at 8am versus 6pm. Light changes a space's temperature, its scale, its mood — the same room reads as generous or oppressive depending on where and how it's lit, independent of anything the plan shows.

Good daylighting is drawn in as deliberately as any wall: where the sun falls at each hour, which surfaces bounce it deeper into the plan, which openings are for view and which are only for light.

03 — Context

Form follows a site, not just a function

"Form follows function" is only half the brief. A function can usually be housed in more than one form, and what narrows the choice is everything the site already brings with it — the climate, the slope of the ground, the buildings already standing next to it, the direction of the prevailing wind.

A design that answers the function but ignores the site tends to feel correct on paper and wrong in person — the discomfort of a building that could have been dropped in from anywhere.

An abstract minimalist arrangement of concrete blocks and seating in an outdoor setting. A form answering to its ground, not just its brief.

04 — Space

Negative space carries the object

A single chair in an empty room is legible in a way the same chair in a cluttered one isn't — the emptiness around it is doing as much work as the chair itself. This applies at every scale, from a single object to a whole plaza: what's left unbuilt determines how what is built gets read.

Filling every space to capacity is rarely the ambitious choice. Leaving room around the thing that matters usually is.

05 — Restraint

Good design disappears

A door handle that's comfortable, a stair that's easy to descend without looking down, a room that's simple to navigate without signage — none of these announce themselves. The best-designed parts of a building are frequently the ones nobody mentions, because they never caused a problem worth noticing.

Design that constantly calls attention to itself is usually solving a problem it created. Design that disappears has usually solved the actual one.

A reference table

Architecture leans on a handful of recurring dimensions and proportions — not rules, but starting points that keep reappearing across very different buildings.

Reference Typical value Why it holds
Door height 2.0–2.1 m Set by the human body, not the building — one of the few dimensions that never scaled up.
Golden ratio 1 : 1.618 A proportion found in facades and floor plans long before it had a name.
Modulor unit 226 cm Le Corbusier's system for deriving a building's dimensions from a person with a raised arm.
Comfortable ceiling 2.4–2.7 m Below this, rooms read as compressed; well above it, they start to feel civic rather than domestic.
Stair riser ~17–18 cm A dimension the body corrects for automatically — a few millimetres off and people stumble.

A short glossary

Datum
A reference line or plane everything else in a design is measured against — literal or implied.
Brutalism
An approach that leaves structural material exposed rather than concealing it behind a finish.
Negative space
The unbuilt or unfilled area around a form, which shapes how the form itself is read.
Vernacular
Building methods developed locally, in response to climate and material, rather than imported from elsewhere.
Threshold
The transition zone between one space and another — a doorway, a portico, a change in floor level.
Modularity
Designing from a repeating unit, so parts can be produced, replaced, or rearranged independently.
