The Midtown21 office building is so named due to its 21-storey height and location in the centre of Seattle. The office space in the building is under long-term lease to the biggest online retailer in the world. The building offers highly flexible use, including a large open area that is used for planned or spontaneous meetings. A conference centre in the building also provides rooms for employee training, and 306 parking spaces belong to the property. LEED Gold certification is evidence of the sustainability of the Midtown21 building.

The Class A office property Midtown21 is in the strong-growth sector of Denny Triangle, between the central business district and the South Lake Union area. The property is very close to the Washington State Convention Center and provides excellent access to the Interstate 5 highway. The building’s surroundings are characterised by modern and successful companies.
