Amazon now employs around 20 000 people in Seattle and occupies 15% of the city's office real estate. This has had a major impact, in particular on South Lake Union, Amazon's main campus, which used to be a rough neighbourhood. Transport links have adapted, shops and food trucks have changed, and house prices have risen sharply. The decision to implant the headquarters in the city itself has meant more taxes and jobs for Seattle which, however, has become dependent on the company. Moreover, Amazon is still growing and is constructing a new building due to open in 2017 in the city to be connected by streetcar to the current headquarters. The new offices called "biospheres" (above) will employ a full-time horticulturalist to look after the 300 plants from 30 countries which will grow inside the building.
