There are no interior structural support walls in a Monolithic Dome, which makes remodeling or retasking the use of the building less expensive to do.
If your objective is to stand out from the crowd to advertise your business a dome is a cost-effective method of doing so. No need to put up odd-angled walls which are less efficient in volume-per-surface area, or vast tracts of windows, or vast areas of walls devoid of windows to make your box look different than the neighbors:http://tinyurl.com/azy4q9http://tinyurl.com/cesq2z
If I say "think of an arch structure", what percentage of people will first think of the St. Louis arch?
If I say "think of a retangular skyscraper", what percentage of people will think of the Empire State Building, what percentage of people will think of the Sears Tower, what percentage of people will think of the Petronas Twin Towers, etc.
A business dome will do it's own advertising by being a unique landmark.
