The Space Needle underwent some great changes in the early ‘80s. The revolving restaurant got a facelift, the top house was renovated, and most noticeably, the 100-foot “SkyLine Level” was added. Housing banquet facilities, the SkyLine Level was part of the original Space Needle design but wasn’t built until now.

The total tab for building and renovation was $5 million — about what it cost to build the Space Needle in the first place.
