The Space Needle is one of the most recognizable landmarks in the world and is a treasured Seattle icon. Built for the 1962 World’s Fair—the Century 21 Exposition whose theme was “The Age of Space”—the tower’s futuristic design was inspired by the idea that the fair needed a structure to symbolize humanity’s Space Age aspirations. Since its grand opening on April 21, 1962, the landmark continues to symbolize the innovative and forward-thinking spirit of Seattle. Located at Seattle Center, the Space Needle stands at 605’ tall and is one of the most photographed structures in the world. The tower’s 520’ saucer-shaped “top house” offers visitors Seattle’s only 360-degree indoor and outdoor panoramic views of downtown, Mount Rainier, Puget Sound, and the Cascades and Olympic mountain ranges. To further elevate the visitor experience, the Space Needle embarked on a multi-year venture focused on the preservation and renovation of the 57-year-old icon. The first phase of the renovation, completed in late summer 2018, includes breathtaking, multi-level, floor-to-ceiling glass viewing experiences including an upper level outdoor observation deck with open-air glass walls and Skyriser glass benches. The Oculus, a grand wood, steel, and glass staircase connects the upper-level to The Loupe, the world’s first, and only, rotating glass floor below. The new glass floor experience opened up a never-before-seen downward view of the structure and the surrounding area, putting Seattle, literally, at your feet. Visit the renovation page to learn more about how the Space Needle is further enhancing its visitor experience. The Space Needle is proud to support local organizations who make a positive difference in the Puget Sound region through its community giving and engagement programs. Visit the Space Needle Foundation page to learn more about the Space Needle’s community giving and guidelines.

When WithinSodo was conceived, the Sodo building had existed as a metal shop, an industrial equipment sales location, and a warehouse for furniture storage. The bones were strong, the space open, and the character authentic. Highlighting the natural materials and creating a “function through form” design was the goal. We wanted to build a space that could adapt to and house a wide variety of events, from an hour-long photo shoot to a day-long corporate retreat and everything in between. The execution of a “flex space” required careful consideration to conform to as many different concepts as possible. The addition of kitchen and bar facilities as well as a rooftop deck brings an entirely new level of versatility and something unique to the Sodo neighborhood. The finished space consists of three dividable rooms of 1600 square feet each, a 3000 square foot roof deck, three bathrooms, a caterer’s kitchen, two bars, an 80" projection screen and audio ran throughout. With a total capacity of 500, WithinSodo caters to almost any type of event you can imagine. Our total allowed capacity is 625 – 450 downstairs and 175 upstairs. We continue to get inspired by WithinSodo and hope that you will too.
