NBBJ is working with Amazon, the world’s largest online retailer, to revitalize Seattle’s Denny Regrade neighborhood with the creation of new corporate office space, ground-level retail and public amenities.

The project encompasses approximately 3.3 million square feet on three city blocks, including three 37-story high-rise office towers, a mid-rise office building, a multi-purpose meeting center that seats 2,000 people, and the landmark The Spheres. To reflect Amazon’s community-focused culture, the design seeks to build a neighborhood rather than a campus, with emphasis given to ground-level amenities open to the public and to diversity in building character.

For instance, ground-level retail on each street front, sheltered pedestrian arcades and public art create a vibrant mixed-use neighborhood in an urban area formerly dominated by surface parking lots. The design also includes a public dog park, two-way cycle track on 7th Avenue, with dedicated entrances for bicycle commuters immediately adjacent to the main lobbies, and tower curtain-wall systems that extend upward to screen the rooftop mechanical equipment.

The first high-rise, named Doppler, was completed in 2015. At 37 stories tall, it contains offices as well as ground-level retail and restaurants, and it also links to the five-story, arena-style multi-purpose meeting center, which will serve the entire headquarters. The second high-rise, Day One, opened in 2016.

The Spheres

The centerpiece of the new Amazon headquarters is The Spheres: a multi-story, glass-enclosed workplace containing tens of thousands of plants and trees from around the world. As exposure to nature is proven to put people at ease and help them think more creatively, The Spheres are designed to help Amazon employees feel and work their best, and are open to the public on weekends.

Center of Energy

On the lower floors of the high-rise buildings, NBBJ also designed the Centers of Energy: social hubs filled with employee amenities that bring an urban vitality into the workplace, encouraging employees to connect and collaborate outside of the traditional office environment.

The Center of Energy contains a range of employee amenities, including a marketplace, food venues, labs, tech support, meeting areas, an outdoor terrace and other alternative workspaces.


Because choice is increasingly important in the workplace, spaces throughout the Center of Energy are designed to accommodate multiple functions, from dining to team meetings to heads-down work.


Research has shown that, when stairs are visible and well-designed, as in the Center of Energy, employees are more likely to make the healthy choice of walking instead of taking the elevator.


Design features throughout the Center of Energy connect employees to the company’s mission, as in the conveyor rollers — like those used in Amazon distribution centers — employed as room dividers.
