Corporate web design

Looking at a few web designs that are attempting to appeal to the corporate world I came across this site:

This site is actually a minimalistic, organic style meant to appeal to an individual who is already in over their head with there website management.  The wood element gives the homepage banner an "old-school" office desk feel.  One thing about the layout of this site is that it is very scan-able.  This is perfect for someone who is looking for solutions in simplicity.  There are not that many interior pages therefore a very simplified navigation. I both like and dislike the use of the use of the basic san-serif font for the navigation.  On one hand it lends itself to the simplicity of the site, however, visually it doesn't quite flow with the typeface of the logotype.

Viewing it again, I think the reason it clashes with the logotype is because it is on the same level.  Dropping the navigation lower would put it at a more appropriate hierarchy level.

This speaks to me that audience is the top priority for design.  Companies that have "corporate" looks are not necessarily trying to appeal to other corporations.  The look sets the tone which should be entirely dictated by the audience that the site is trying to appeal to.
