A Single Column over Multiple Rows - css

Question

Is it possible to achieve this?
By slightly modifying this codes?
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-6"></div>
<div class="col-md-3"></div>
</div>
EDITED
I can achieve this using below. I'm wondering if there's any other simple way.
<div class="row">
<div class="col-md-3"></div>
<div class="col-md-9">
<div class="row">
<div class="col-md-8"></div>
<div class="col-md-4"></div>
</div>
<div class="row">
<div class="col-md-8"></div>
<div class="col-md-4"></div>
</div>
</div>
</div>

You may try it by
just add a single div in start and add its height plus hide the lower div
<div class="row">
<div style="height:10px(according to you)" class="col-md-3"></div>
<div class="col-md-6"></div>
<div class="col-md-3"></div>
</div>
