The siding behind Chur’s freight depot has not seen a train since 2009. For a decade it was a strip of ballast and buddleia, fenced off, visited by foxes. In the summer of 2024 three architecture students from Mendrisio cut the fence, laid a floor of reclaimed sleepers across the rails, and built a room on top of it.1Footnote 1: The sleepers came from the same siding; the students lifted them from the dead track and relaid them across it, so the floor is the railway turned ninety degrees.
The room is nine metres by six, framed in spruce from a sawmill two valleys over, clad in larch boards left rough. One wall is a sliding panel painted red; when it is open, the room is a stage, and when it is shut, it is a shed. There is a bench along the back wall and nothing else. It took eleven days and cost, by the students’ own accounting, 4,200 francs, most of it screws.
Nobody asked for it. That is the first thing the city said, and it remains technically true. But by the end of that first summer the pavilion had hosted a choir, a repair café, two weddings and a Tuesday-evening Albanian language class that is still running.2Footnote 2: The class moved from a community-centre basement with no windows. The teacher says attendance doubled once there was weather to look at. The fence was never repaired. The foxes, reportedly, adapted.
What interests us is not the story, which is the kind of story architecture magazines tell too often, but the drawing. The students produced a single axonometric, A3, in pencil, with the red panel the only colour. It was pinned to the pavilion itself, inside a plastic sleeve, and it was the building’s entire planning submission, retroactively.3Footnote 3: The city’s building department accepted the drawing as a temporary-structure notification in October 2024. The temporary permit has since been renewed twice. The axonometric shows everything: the sleepers, the frame, the panel, the bench. It shows nothing that is not there. It is the most honest piece of architectural representation we have seen this year, and it was not meant to be seen at all.
The city’s problem is now a budget line. The pavilion needs a roof membrane before its third winter, and the students have graduated. A proposal to replace it with a “permanent community structure” from a local firm, with a café and a toilet block, has been rejected by the people who use it on the grounds that it would be a building.
They are right. The pavilion works because it is barely there: a floor, a frame, a wall that moves. The proper response is not to upgrade it but to maintain it, which is unglamorous and cheap and requires only that someone be paid to go and look at it twice a year. Cities are good at commissioning. They are much worse at looking.
