Islington is the densest borough in the country by population, and almost none of its housing was purpose-built as flats. Georgian and Victorian houses subdivided over decades leave a warren of unsealed voids between units, so a problem in one flat is rarely contained to it. Upper Street's restaurant strip and the Regent's Canal at the southern edge supply the food and the highway.
