A new website is hoping to start answering some of those questions. [Im]possible Living is a crowd-assisted map site that's identifying vacant properties all over the planet, though mostly in Italy so far. It's not just pointing out the black eyes of the urban landscape. The site is trying to play matchmaker between abandoned spaces and people with ideas to revive those spaces, and maybe even some of the money they'll need to get things going.
Making the leap from mapping properties to actually implementing projects is a big one, and Sesta says he doesn't have any delusions about how hard it will be. But he sees potential for both crowdsourcing and corporate social responsibility campaigns to help create some of the funding needed to repurpose these spaces. Though right now it's mostly just a map of places, Sesta is hopeful that the site will become a showcase for projects that have successfully transformed abandoned properties and that the community it creates can start to tap into these underutilized assets in cities all over the world.
