The takeover of our cities

Saskia Sassen, Guardian-

• The sharp scale-up in the buying of buildings, even in cities that have long been the object of such investments, notably NY and London. For instance, the Chinese have most recently emerged as major buyers in cities such as London and New York. Today there are about 100 cities worldwide that have become significant destinations for such acquisitions – foreign corporate buying of properties from 2013 to 2014 grew by 248% in Amsterdam/Randstadt, 180% in Madrid and 475% in Nanjing. In contrast, the growth rate was relatively lower for the major cities in each region: 68.5% for New York, 37.6% for London, and 160.8% for Beijing.

• The extent of new construction. The rapid-growth period of the 1980s and 90s was often about acquiring buildings – notably high-end Harrods in London, and Sachs Fifth Avenue and the Rockefeller Center in New York. In the post-2008 period, much buying of buildings is to destroy them and replace them with far taller, far more corporate and luxurious types of buildings – basically, luxury offices and luxury apartments.

• The spread of mega-projects with vast footprints that inevitably kill much urban tissue: little streets and squares, density of street-level shops and modest offices, and so on. These megaprojects raise the density of the city, but they actually de-urbanise it – and thereby bring to the fore the fact, easily overlooked in much commentary about cities, that density is not enough to have a city.

• The foreclosing on modest properties owned by modest-income households. This has reached catastrophic levels in the US, with Federal Reserve data showing that more than 14 million households have lost their homes from 2006 to 2014. One outcome is a significant amount of empty or under-occupied urban land, at least some of which is likely to be “re-developed”.
