Step inside Sonic Tower - one of two new office towers in downtown Bellevue that expand Amazon's Puget Sound headquarters. The Sonic Tower is a laboratory for accommodating the different ways people work, especially as employees return to the office after the pandemic. " Centers of energy" are connected by Synergi stairs throughout the building. Sonic's design is grounded in nature, with light fixtures above staircases resembling waterfall mist or steam, horticulture installations, and more.
