The side of the building is being covered with multi-colored leaves from Apple's logo, matching the invitation sent to members of the press earlier this month.
AppleInsider reader David Jones snapped a photo of the building and a design schematic which shows the finished layout.
Apple is expected to unveil a new iPad 5 and a Retina Display iPad mini 2 at the event. There have also been rumors that Apple could use the event to release OS X Mavericks and possibly update its MacBook Pros.
