Walk Appeal promises to be a major new tool for understanding and building walkable places, and it explains several things that were heretofore either contradictory or mysterious. It begins with the assertion that the quarter-mile radius (or 5-minute walk,) which has been held up for a century as the distance Americans will walk before driving, is actually a myth.
Both images below are at the same scale, and the yellow dashed line is a quarter-mile radius. On the left is a power center. As we all know, if you're at Best Buy and need to pick something up at Old Navy, there's no way you're walking from one store to another. Instead, you get in your car and drive as close as possible to the Old Navy front door. You'll even wait for a parking space to open up instead of driving to an open space just a few spaces away… not because you're lazy, but because it's such a terrible walking experience.
The image on the right is Rome. The circles are centered on the Piazza del Popolo (North is to the left) and the Green radius goes through the Vittorio Emanuele on the right. People regularly walk that far and then keep on walking without ever thinking of driving.
In 1964, the historian Bernard Rudofsky curated a show at MoMA called Architecture Without Architects, celebrating the formal qualities of a range of traditional building practices drawn from around the world.
Setting aside the endlessly troubled implications of the Western gaze on “primitive” cultures, the show had the very constructive impacts of encouraging formal diversity at a time when mainstream architecture had grown desperately, myopically monochromatic and of suggesting that “non-architects” were capable not only of making good judgments about their environments but of actually taking the lead in creating them.
