I will say that your document semantics are quite vague. You probably don't need to use STRONG inside your heading - it's conceivable that you really mean to emphasize the thought expressed in it, but I suspect that you only want the heading to appear bolder. Use CSS to achieve that, as in: h4 {font-weight:bold; font-size: 14em;}
.
It's also conceivable that your page makes the most sense with the navigation starting at the fourth level of some topic, but it's highly unlikely; in the vast majority of cases, the navigation would exists higher up - under h1 or h2.
Your navigation itself would be more coherent if it was an unordered list.
<ul>
<li>Home</li>
<li>About Us</li>
...
</ul>
This also has the advantage of allowing you to style the navigation elements both as a set and individually.
You probably don't need to be wrapping your elements in all those divs. Most elements in HTML are containers - headings, lists, paragraphs, just about everything can be styled - including positioning and moving - by itself.
For instance, one means of positioning the navigation list to the right of the h4 would be to style the h4 with "display:inline", or "float:left", which would bring the following element (the list) onto the same line. There's a lot of different ways to go about that kind of positioning, and it's not even clear that this is what you're after.
Clarify what you mean; and it would help if you posted whatever CSS or JavaScript you're using.
