Please note that all heights shown in italics/red are estimated heights. These have been calculated based on known floor counts for the building, then extrapolated through analyzing typically hundreds of buildings of the same function on this database that do have confirmed heights. The user should be aware that non-standard building features, such as significant spires or raised entrances / podiums, may affect the accuracy of these estimations.
