First-time travelers to Amsterdam — perceptive ones, anyway — need only to spend a day navigating its cobbled streets to notice what makes the experience so singular. The buildings are old and narrow, and many seem perilously cockeyed. With their decorative facades and fanciful gables, they resemble oversized gingerbread houses. And when you walk by them, you witness a sight even more peculiar than all of the above: an unobstructed view straight into the living rooms and kitchens of the people who live inside, who refrain from hanging curtains even at ground level. As a locally based friend explained to me on a recent visit, the Dutch may value privacy just as much as the rest of us, but they also take a certain pride in proving they have nothing to hide. This was the thought running through my mind the day that Renny Ramakers, co-founder and director of the influential Dutch design laboratory Droog, let me wander around inside her home unsupervised, snapping hundreds of voyeuristic photos of her possessions while she worked calmly away at her dining table.
