A $100 million makeover of Seattle’s Space Needle has been completed, with the observation tower receiving a cantilevered staircase, and the world’s first revolving glass floor.

The renovation was designed to clear the way for more impressive views of the city, replacing tower materials with 176 tons of glass. Wire caging and security walls have been replaced with glass panels, sloping outwards with open sky above. The new panoramic views are complemented by thick glass bench seating, intended to create a floating sensation for visitors.

According to New Atlas, floor-to-ceiling glass windows have also replaced partial walls for improved views from inside the observation deck. A new staircase leading to the lower level is also cantilevered from the Space Needle’s core, freeing it from easily visible supporting structures.

A glass floor on the lower observation deck, called The Loupe, also provides guests with aerial views of the ground from 500 feet above. It’s construction involved hoisting 37 tons of glass into the sky, arranging it into 10 seperate layers. Six layers make up the revolving portion of the floor, completing one full rotation every 45 minutes.

"The Space Needle was built to help define the skyline of Seattle, but has become so much more," Karen Olson, CMO, Space Needle told Atlas. "The Space Needle became the visual icon of the city and a symbol for the spirit of Seattle. The original designers of the Space Needle dreamed big, and we continued their vision with this renovation. With glass walls, glass barriers, glass benches, and even glass floors, visitors can feel like they're floating over the city. The Space Needle has always featured some of the best views of the Pacific Northwest. Now it offers some of the most thrilling."
