Very few things in our everyday thrive by doing absolutely nothing. The floor might just be a rare exception; devoid of any vitality or ambition—characteristics at odds with a society obsessed with progress—it remains unapologetically passive. Yet, despite its unyielding commitment to inertia, the floor remains largely ignored and relegated to the background. One would think that its sheer size alone, comparable to that of the lesser tamed ground that we trample upon outdoors, ought to make it a subject of wide interest. As the only building element that we physically contact with the most, our expectations of the floor are disappointingly pragmatic; it should not shake, give way, or tilt. Mostly, it should be flat as we all know of those amongst us, who descend into melodramatic despair each time they encounter an uneven floor, though the rationale behind such obsession with flat-ness is beyond us here. ‘Science of the Secondary: Floor’ is the fifteenth edition in the series of ongoing research conceived and developed by Atelier HOKO.
