Any major anniversary carries with it a baggage of minor ones, and so it is in 2014. When Europe marks the 100th anniversary of the start of the First World War later this year, few people will be thinking about architecture. And yet it was the devastation of Flanders in the autumn of 1914 that inspired Le Corbusier to design the Maison Dom-ino, a standardised construction system for the reconstruction effort that was to come. That simple drawing has haunted architecture for a century. Indeed, it is far more relevant today than it was then.
