The cited article is nothing more than a sales pitch -- a simple answer to
a
very complex question. A structure, whatever its shape, should be
designed
to resist whatever forces may be imposed, windwise or otherwise. The
shape
of the structure is only one of many factors to be considered in design,
factors such as esthetics, economy, utility and the desire to have
something
unique. Considering these, it is easy to see why circular and dome houses
have not become a standard.

Circular is far from the "best" overall design, but it can be a style to be
admired by some. It has plenty of drawbacks from a practicality point of
view. But if you have the money . . . .

If you want to build for strength, I'd go with concrete. Using insulating
concrete forms is becoming very popular both because of the strength issues
and the energy efficiency. www.integrapec.com www.polysteel.com
www.standardicf.com are just a few of them. I saw pictures of one that
went through a tornado. While there was some damage, the interior was
hardly touched.
