The steel frame of the Alfinach development went up in fifteen days. That number is worth pausing on, but not for the reason it first suggests.
Fifteen days is fast for the structure of a residential development. It is not fast because anyone was rushing. It is fast because, by the time the first column arrived on site, every decision about that structure had already been made, drawn, checked and manufactured somewhere else. The site was not where the frame was invented. It was only where it was assembled.
That is the whole argument of this piece, and it took us a while to see it clearly.
What industrialisation actually is
The word carries the wrong associations. It suggests repetition, standardisation, the same house delivered a thousand times to a thousand indifferent plots. It sounds like a loss of authorship, and architects have spent a century being suspicious of it for that reason.
But industrialisation is not a style and it is not a catalogue. It is a decision about where the work happens, and about when it is decided.
In wet construction, a large part of the building is invented on site. Dimensions are resolved against what is already built. Tolerances absorb error. The trade that arrives second corrects the trade that arrived first. Everyone is improvising within a range, and the range is generous, because concrete and mortar forgive.
In dry construction, nothing forgives. A steel frame does not absorb error. A bolt hole is where it is. The consequence is not that the building becomes rigid — it is that the thinking has to happen earlier, and it has to be complete. The drawing stops being a description of an intention and becomes an instruction that will be executed literally.
That is the real transfer. Industrialisation moves labour from the site to the factory, and it moves the architect’s decisions from the middle of the project to the beginning.
What it gives back
Precision, first. A component made under a roof, on a bench, by someone who makes only that component, is better than the same component made in the rain by someone doing four things at once. This is not an opinion about craft. It is an observation about conditions.
Time, second — but not in the way it is usually sold. Fifteen days on site is the visible surplus of months of resolved drawing. The speed is real, but it is bought earlier, and it is bought with rigour. Nobody saves time by industrialising. They spend it sooner.
Waste, third. Dry construction cuts to measure and bolts together. It produces components, not rubble. And what is bolted can be unbolted — a building assembled is a building that can one day be disassembled, its steel returned rather than buried. The most sustainable structure is not the one with the best certificate. It is the one that can be taken apart.
What it costs
It costs the right to change your mind late. This is a real cost and it should be said plainly.
A project that industrialises its structure gives up the comfortable improvisation of the site. There is no moving the column two hundred millimetres because the room feels tight. The room was decided when the column was ordered. Studios that like to keep options open until the last moment will find this intolerable, and they are not wrong to.
We think the trade is worth making, and not for reasons of efficiency. It is worth making because a discipline imposed early tends to produce a better building than a discipline imposed late. The constraint arrives when it can still be answered with architecture, instead of arriving at the end, when it can only be answered with compromise.
The frame and the finish
Walk through Alfinach today and you will not see any of this. The steel is inside the walls. The curved volumes read as mass. The stone base meets the ground as though it had always been there. Nothing announces the fifteen days, or the months behind them.
This is as it should be. Structure is not a subject. It is the grammar that lets the building speak about other things — about the curve, about the light on the stone, about the way the plan holds a community rather than a set of apartments.
But the grammar decides what can be said. A structure resolved early, precisely, and once, leaves the architecture free. A structure improvised on site consumes the attention that should have gone to the rooms.
The frame was decided elsewhere, in advance. Everything that matters happened before it arrived.
