This tall building height calculator is developed to assist in determining tall building heights when only the story count is known. The calculator is divided into three categories representing the three major functions represented in tall buildings;              (i) Office              (ii) Residential/Hotel              (iii) Mixed-use or when the function unknown The calculator will provide an approximate height for a single tall building, but as tall building characteristics vary significantly with location, structural material, form, profile, etc, in some instances estimates will vary considerably with actual building height. As such, the calculator is best utilized to determine heights in multiple building / statistical studies, where there are many unknown building heights. In these instances the ...
