You can nest rows, I would try something like this <div class="container">
<div class="row"> <div class="span8"> <div class="row"> <div class="span4"> Column 1 </div> <div class="span4"> Column 2 </div> </div> <div class="row"> <div class="span4"> Column 1 </div> <div class="span4"> Column 2 </div> </div> <div class="row"> <div class="span4"> Column 1 </div> <div class="span4"> Column 2 </div> </div> </div> <div class="span4"> column 3 </div> </div> </div>
