It seemed that Londoners, far from being the apathetic and non-community-minded types that they’re often stereotyped as, took real pride in the appearance of their local streets.

It’s this sense of neighbourly pride that inspired the Love Clean London app. It’s a one-stop phone app for reporting fly-tipping, graffiti, blocked drains and even abandoned cars. Send in a location and picture, and experts at the site forward the report to the relevant council department (because finding who you’re actually supposed to complain to on your own can be a kafkaesque experience at the best of times). a quick check of the reports on the London site shows a high success rate—images of freshly painted walls and cleared waste ground replace the pictures of flyposting and old mattresses with a pleasing regularity.

This and more inspiring projects can be found in the print copy of A smart guide to Utopia or the ebook version.
