4/C

4/C, also known as 4th & Columbia, is a proposed very tall building in Seattle, Washington, United States. If built, it would stand 1,020 feet tall with 91 stories, making it the tallest building in Seattle. It would even be the first building of its height in the Pacific Northwest area.

The project has been developed by a company based in Miami called Crescent Heights since 2015. Over the years, the design has changed many times, with three different architecture firms working on it. The latest design is from Skidmore, Owings & Merrill.

As of 2023, plans show that 4/C would have 1,090 places to live. These would include apartments up to the 64th floor and condos from the 65th to the 90th floor. The building would also have coworking spaces and shops for people to use.

History

Crescent Heights bought a piece of land with two parking garages in September 2015 for $48.75 million. They announced plans to build a very tall building called the first supertall skyscraper in the Pacific Northwest, taller than the nearby Columbia Center. The original plan was for a building that would be 1,111 feet tall with 102 stories.

Because of worries that the tall building might affect flights near Boeing Field and Seattle–Tacoma International Airport, the Federal Aviation Administration asked them to make it shorter. In 2016, the plans were changed to make the building shorter and have fewer rooms. Later in 2020, a new design was shown with a tall building that has a special shape to let people see Mount Rainier. By 2022, the plans included many places to live and work together. In 2023, Crescent Heights decided to sell the land.

Design

The new design for the building is a very tall tower with 91 floors and a height of 1,020 feet (310 meters). It will have about 1.2 million square feet (110,000 square meters) of space inside, mostly for homes. There will be 1,090 places to live, with smaller homes from the 3rd to the 61st floor and larger homes from the 65th to the 90th floor. The top three floors will have very big special homes called penthouses.

There will also be special areas for people living there on the 62nd and 63rd floors, and places to work and relax on the 9th and 10th floors. The building will have shops on one side and 873 parking spots underground and on five floors above ground, using a special lift for cars instead of ramps. Earlier plans suggested turning the parking area into homes and offices later.
