The Amazon Phase VI office complex consists of two buildings located at 515 Westlake Avenue North and 500 Ninth Avenue North, with LEED Platinum certification. They are let on a long-term lease to online retailer Amazon, which has its global headquarters in Seattle. The Class A complex also houses a selection of restaurants and cafés and is one of the best office addresses in the South Lake Union submarket due to its high level of construction quality. South Lake Union has undergone a rapid transformation from an industrial area to a lively urban neighbourhood and now attracts high-tech companies from around the world.

The Amazon Phase VI office complex is located in the South Lake Union district, one of the most sought-after office submarkets in north-central Seattle. The banks of Lake Union and the associated park are just a few metres away, while the many public transport stops nearby provide excellent connectivity.
