Shouldn't Crowdsourced New York Apartment Pushing Limits actually be an Onion headline? Either that or the core of a new ResPublica/New School Network collaboration as the Big Society's contribution to solving the housing crisis. We'll crowdsource it! If everyone brings a brick, we'll have...a pile of as many bricks as users who actually bothered showing up, that the two people who actually care about the project will have to use.
(Yes, I know this should be on Stable & Principled, but I'm trying to keep that blog Terribly Serious.)
Meanwhile, genuinely serious and interesting points on the same theme are made in this excellent piece on Park Hill in Sheffield and its redevelopment. It's not as smash-mouth as Owen Hatherley would likely be, but it also makes the point that letting the squatters have their way with it was tried, effectively, and a lot of the work required on the building was basically making good the results. It also strikes me as a good point that it's not, in fact, easier to run away from the scene of a crime on an access deck. Of course, the real point here is that as the society that built it crumbled, they stopped providing proper investigative policing to the people in it and started treating them as the object of mass public-order policing.
