Tall Buildings in Numbers A Look at Occupiable Telecommunication & Observation Towers With the recent completion of two megatall telecommunication/observation towers – Canton Tower in 2010 and Tokyo Sky Tree earlier this year – it is time to review these structures and explain why they are distinguished from buildings in the Council’s official tallest lists (found at www.skyscrapercenter.com). To be considered a “building” a project must achieve three milestones: 1) it must be complete, 2) it must be freestanding and, 3) at least 50% of its height must be occubiable 1 space. While projects like Canton Tower and Tokyo Sky Tree are indeed complete, free standing and partially occupiable – making them distinct from many of the world’s other telecommunication structures – less than 50% of their height is occupiable and thus the projects cannot be considered “buildings.” The following is a study of the world's “supertall” (300 m+) occupiable telecommunication & observation towers (referred to as “occupiable T&O towers” in the study) – some 36 of which now exist in 23 countries around the globe. Notes: 1 “Occupiable” refers to Occupiable T&O Towers conditioned space which is The world’s 10 tallest occupiable Telecommunication and 2 designed to be safely and legally Observation (T&O) towers according to “Height to Tip” occupied by residents, workers or 1 are displayed below, with a blue highlight showing the other building users on a Tokyo Sky Tree location of occupiable space.
